CoatingSkinPress fittings’ coating significantly improves mechanical and visual properties. The fittings are plated with a 4-to-8-micron (µ)-thick layer composed of more than 99.9% tin (according to DVGW W534 and ISO 2093). This improves the fittings’ appearance and reduces the risk of oxidation.

These fittings have successfully passed tests for detection of applied or residual stresses which can cause failure of the material in service or storage through stress corrosion cracking:

- salt spray (fog) test following ISO 6957: 1988

- mercury(I) Nitrate test following EN ISO 196: 1995

Inner diameterSkinPress fittings’ optimised inner diameter lowers pressure loss.

Note: The inner diameter at the centre of the fitting is never smaller than the inner diameter at the ends of the fitting.

1.2.4. O-ringsThe standard fittings for water and heating are provided with EPDM O-rings.

The type of O-ring to be used depends on the application and the medium. For this reason, the gas press-fittings are provided with HNBR O-rings.

SkinPress and SkinPress Light fittings feature a joint designed to indicate unpressed fittings, on 14, 16, 18, 20, 26 and 32 mm diameters. When the fitting is not crimped, the O-ring will leak water. This simplifies the detection of unpressed fittings during pressure testing.

Range Type O-ring Operating Temperatures

SkinPress water SkinPress Light(ø 14 to 32)

EPDM (black) -20°C to +95°C

SkinPress gas HNBR (yellow) -20°C to +60°C

Patented O-ring functionThe patented O-ring is designed using a leak path within the O-ring itself.

Small grooves have been placed at three strategic points on the surface of the O-ring. Water will flow through these grooves when the fitting is not crimped. When crimped, the rubber blocks the grooves. This creates a fully water- and air-tight connection.

1.2.5. Crimping ToolsPress tools consist of a pressing machine and the corresponding jaws, inserts, adapters and chains. The pressing machine can be either battery- or mains-powered. For each pipe diameter, the correct components should be used for a perfectly tight connection (see table below).

COMAP’s rangeCOMAP offers a range of pressing tools designed to ensure reliability and simplicity for professionals. Novopress ACO 102, ACO 202 and ECO 301 and Klauke MAP2L and UAPL3L tools allow crimping of all diameters of copper, PEX, multilayer, carbon steel and stainless steel pipe. The system of inserts and jaw allows tools to be used with Multisertissage®, simply by changing the inserts (rather than the large and heavy jaws).

1.3.2. MultiSkinCOMAP MultiSkin multilayer pipe consists of a continuous aluminium pipe, butt-welded lengthwise, with inner and outer layers of electron beam cross-linked polyethylene. The different layers are bonded together with a high-quality adhesive layer. The result is COMAP MultiSkin pipe, which combines all the advantages of synthetic materials and metal pipes.

The inner and outer layers are fabricated from high density polyethylene (HDPE) granulates, after which they are cross-linked by electron beams. Cross-linking considerably improves the natural qualities of the polyethylene and heightens resistance to pressure and to temperature fluctuations.

The pipe meets the requirements of the strictest of standards for drinking water installations, and is also resistant to aggressive substances.

The aluminium layer guarantees the oxygen-tightness and shape-retaining properties of the pipe. The longitudinal butt welding of the aluminium pipe means the aluminium retains uniform thickness along its whole length. Consequently, when the cross-linked outer layer is adhered to the aluminium layer, it will also have uniform thickness. This also offers advantages when pressing, as the press loads are perfectly distributed. Depending on the diameter of the pipe, the thickness of the aluminium layer is calculated so the pipe always retains optimal flexibility and pressure-resistance.

Polyethylene is a plastic that consists of different chains of molecules. These chains are not directly connected to each other. The basic structure is kept together by weak mutual forces between the molecules. When heated, these molecule chains tend to move further and further apart, making the material softer, more elastic and less pressure-resistant — and therefore less appropriate for sanitary and heating uses.

Exposing the multilayer pipe to intense electron beams causes cross connections between the different molecule chains of the plastic. The electrons cause the hydrogen atoms to split from the different polyethylene chains. The carbon atoms are then allowed to join and form a strong cross-linked structure.

The cross connections mean the movement of the chains with respect to each other is kept to a minimum. So, when the pipe comes into contact with high-temperature fluids or another source of energy, its reinforced structure will not sustain damage. Cross-linked polyethylene displays optimal behaviour under continuous loads due to pressure or temperature. Reticulation makes the material more durable and gives it heat retention properties.

COMAP provides MultiSkin pipes with both the inner and outer layers consisting of PE-Xc, electron beam cross-linked polyethylene.

Product Benefits

} Temperature and pressure resistant: maximum working temperature of 95°C, and maximum working pressure of 10 bar.

} Low heat expansion: the presence of the aluminium layer means the pipe’s expansion coefficient is comparable to that of copper and 8 times less than that of an ordinary plastic pipe. Coefficient of expansion is 0.025 mm/mK.

} Minimal pressure drop: the smooth surface of the pipe’s inner and outer layers prevents build-up of scale or other debris. In this way, these smooth surfaces reduce pressure drop.

} Shape-retention: after bending, the pipe retains the required shape. It does not have heat retention, like other synthetic pipes . This simplifies and speeds up installation of pipes.

} Wear-resistant: the outer and inner layers are made of electron beam cross-linked polyethylene. They do not sustain wear, even at high temperatures or flow rates.

} Impermeable to oxygen: the integrated aluminium layer prevents the penetration of oxygen into the pipe.

} Light and easy to handle: fast and simple installation saves time and money. The pipe is flexible and extremely light. A 200 m roll of MultiSkin 16x2 pipe weighs only 25 kg.

} No noise nuisance: Unlike with metal pipes, this pipe does not cause acoustic nuisance due to flow noise, if the pipe diameter has been correctly selected. Contact noise can be avoided with correct installation.

} Corrosion resistance: PEX is inherently impervious to corrosion.

1.3.2.2. MultiSkin pre-insulatedMultiSkin pipes are to be used with round thermal insulation made of extruded PE foam, provided by the manufacturer, which protects the pipe against condensation, heat loss, expansion and noise transmission.

Furthermore, pipes should be insulated where they cross each other, which causes raised temperatures (floor heating effect). PE foam is protected by extruded PE-film coloured red or blue. Heat insulation is CFC-free, and has the following properties:

MultiSkin4 Twin Corrugated MultiSkin4 Twin Corrugated pipe consists of two MultiSkin4 PEXc/AL/PEXc pipes and two polyethylene sleeves, connected by means of a perforated strip, all on one coil. The inserts keep all elements together and ensure a perfectly finished installation.

In addition, the perforated connections allow separation of the sleeves where necessary.

To distinguish the contents of the sleeve pipes, one of the two silver-grey sleeves is marked with a red line.

1.3.2.4. MultiSkin4 GasThe COMAP system for gas is only allowed in countries where testing has taken place and certification given, such as in the Netherlands and Italy.

The system has Kiwa gas approval and is intended for the construction of gas installations within the home and for the transportation of gas according to NPR-3378-10/NEN 1078 part 10.

The system consists of MultiSkin4 pipe (PEXc/AL/PEXc), SkinPress press-fittings for gas, and protective sleeves. The pipes and sleeves are coloured yellow, with imprints indicating the brand and KIWA gas approval.

To protect the pipe during construction work, it is recommended to use polyethylene protective sleeving.

1.3.3. BetaSkinBetaSkin is a full range of multilayer pipes, from diameters 14 to 32 mm, in PE-RT with a light aluminium core, for better pipe flexibility.

Produced according to the EN ISO 21003 standard, the pipes are available in lengths, rolls, pre-insulated and protected in a corrugated conduit.

BetaSkin multilayer pipes combine all the advantages of plastic pipes and metal pipes. They are flexible and robust, with high pressure and temperature resistance.

BetaSkin pipes consist of a 0.2 mm layer of butt-welded aluminium, with an inner layer of PE-RT and an outer layer of PE-RT polyethylene. The layers are assembled with a high-performance adhesive agent.

ApplicationsHeating and cooling, drinking water, rainwater, fuel oil, and other applications (contact COMAP).

Product Benefits

} Temperature and pressure resistant: maximum working temperature of 70°C, and maximum working pressure of 10 bar.

} Low heat expansion: the aluminium layer means the expansion coefficient is comparable to that of copper and 8 times less than the coefficient of expansion of ordinary plastic pipe. Coefficient of expansion of 0.023 mm/mK.

} Minimal pressure drop: the smooth surface of the pipe (inner and outer layers) prevents build-up of scale or other debris. This smooth surface leads to minimal pressure drop.

} Shape retention: after bending, the pipe retains the required shape. It does not have heat retention, like other synthetic pipes. This simplifies and speeds up installation of pipes.

} Wear-resistant: the outer and inner layers are made of electron beam cross-linked polyethylene, so they are not affected by wear, even at high temperature or flow rate.

} Impermeable to oxygen: the integrated aluminium layer prevents the penetration of oxygen into the pipe.

} Light and easy to handle: fast and simple installation saves time and money. The pipe is flexible and extremely light. A roll of 200 m BetaSkin 16x2 weighs only 21 kg.

} No sound nuisance: Unlike with metal pipes, this pipe does not cause acoustic nuisance due to flow noise, if the pipe diameter has been correctly selected. Contact noise can be avoided with correct installation.

} Corrosion resistance: PEX is inherently impervious to corrosion.

2.1.3. Thermal expansion compensationNote: To calculate thermal expansion, see chapter 3.2. Thermal expansion.

Z- and L- shaped expansion compensation

In case of significant expansion, compensation must be calculated and the results applied to the installation setup. This will avoid overly powerful tension in the system, which could deform and damage the connections. The

formula used to calculate expansion compensation is as follows:

Fixed point or fittingSliding points

Example: Calculating the allowance in a distribution network comprising 24 m of 20 mm multilayer pipe that experiences temperature variation of 50°C.

We need to calculate the length of compensator (Bd) needed to accommodate expansion (∆L).

∆L = α x L x Δθ = 0.025 (MultiSkin4 coefficient) x 24 m x 50°C = 30 mm

The network’s linear dilation is 30 mm (according to Chapter 3.2 on linear dilation).

Using Graph 1 or Table 1, we arrive at a compensation length of approximately 800 mm (see red marks).

The analytical calculation shows: Bd = k1 x √(de x∆L)

U-shaped equalizerNote: To calculate thermal expansion, see chapter 3.2 on thermal expansion.

In case of significant expansion, U-shaped compensating loops may be fitted at installation. This will avoid tension within the system, which could deform and damage the connections. The formula used to calculate expansion compensation (in mm) is as follows:

2.1.4. Attaching pipesCorrect compensation for expansion also depends on the use of pipe-installation methods such as saddles and clips.

Attachment points must be on straight pipe segments. Attachments cannot be located on fittings. Never use sliding fixtures as attachments near to a pipe connection. It is recommended that pipe saddles be installed such that they are not used as fixed supports.

When straight segments of pipe exist without expansion compensation, only use one sliding fixture to prevent any deformation. Position this fixture as close to the middle of the straight pipe segment as possible: in this way, any expansion will be distributed in both directions and the length required to compensate expansion will be halved.

Space required between two fixtures:

The use of sliding fixtures with rubber lining is recommended to attenuate any noise and vibrations and improve the distribution of stresses.

When pipes from one storey run to a riser pipe within a shaft, these pipes must be able to move freely. Here, too, the change in length can be accommodated with an expansion bend. The expansion bend will absorb the upward and downward movements.

If the shaft is large enough and there is space to fit the calculated expansion bend, the pipe must simply be equipped with a protective sleeve at the point where it passes through the wall.

If the shaft is too small to fit the calculated expansion bend, the hole in the wall will have to be made larger to give the pipe sufficient room for movement. At the point where the pipe passes through the wall, it must be insulated using polyethylene.

2.1.5. EmbeddingTo accommodate the expansion of the pipe within the structure, you must provide insulated expansion bends at least every 10 m. When this has been done, bare COMAP pipe can be encased (in sand or cement) or placed in the wall.

We recommend always using a protective sleeve, or if possible, insulation.

The sleeve has a protective function, while the insulation not only protects and thermally insulates the pipe, it also prevents the formation of condensation.

To determine the insulation thickness you can apply the following rule: 1.5 x ∆L (change in length).

The metal parts of the flush mounted fittings must be protected against corrosion. This can be by means of easily accessible, waterproof built-in boxes, tape-sealed sleeve, or a tape-sealed sleeve made of a synthetic cellular material. The materials used for this must not affect neither the pipe nor the fitting.

Like pipes that pass through walls, pipes that pass through ceilings must be equipped with sleeving at minimum. In addition, they should never be bent using a sharp corner, to prevent kinking. It is advised to round off the edges.

2.1.6. Recommendation for gas installation (NPR 3378-10 NL)} The piping route must be selected to minimise the likelihood of damage by, for example, drilling or nailing.

} When bending, observe the minimum bending radius, as specified by the manufacturer. Avoid bending pipes.

} In walls, channel depth must be such that the distance of the pipe to the external face of the wall is at least 10 mm.

} In floors, the distance from the pipe to the external face of the floor must be at least 20 mm.

} During construction work, the gas pipe must be closed off, so no dirt or dust can enter the pipe. If dirt has entered the pipe, the pipe must be cleaned with an inert gas or with air.

} Pipes and connections showing signs of surface damage must not be used.

} A pipe sleeve must be used when a pipe passes through a (cavity) wall. In addition, the shortest route must be chosen. 2.

2.2. Installation2.2.1. Cut the pipe to lengthWith a pipe cutter, cut the pipe by positioning the tool at a 90° angle. This ensures a square cut without burs. Don’t forget to add the length of the pipe that is situated inside the fitting in your calculation (Dimension «A»).

2.2.2. Deburring pipes Use a COMAP calibrating tool to restore the pipe’s cylindrical shape and remove burrs. Visually check the that the pipe edge is clean and bevelled. This ensures that the O-ring in the fitting will not be damaged.

2.2.3. Assembly of fittings and pipesInsert the pipe into the press fitting up to the marked insertion depth while rotating slightly and pushing in an axial direction at the same time. The marking for the insertion depth must still be visible. In case of fittings without a stop, fittings should be inserted at least as far as the marked insertion depth. The pipe must not be inserted into the press fitting in a rough or careless manner, because this may result in damage to the O-ring.

Note: SkinPress fittings in brass and in PPSU may be installed in temperatures up to -10°C.

2.2.4. CrimpingBefore starting to press, the press jaws and chains must be checked for contaminants. Any impurities found must be removed. Furthermore, the press machine must be in good working condition and the operating and maintenance instructions provided by the manufacture must be complied with.

Use the correct pressing jaws and chains for the chosen fittings.

In order to create a proper pressed connection, the groove of the press tool must enclose the SkinPress fitting’s Visu-Control® ring. Once the pressing process is begun, it must not be interrupted.

The patented Visu-Control® technology offers visual and tactile pressing confirmation (by deformation of the ring).

Note: It is strictly forbidden to remove or break the Visu-Control® ring. This will prevent the system from functioning correctly and reduce its expected lifespan.

3.2. Thermal ExpansionNote: To calculate thermal expansion, refer to page 29 (2.1.4. Compensating for thermal expansion).All metals expand when heated and contract when cooled. It is necessary to consider

the differences in pipe length that result from temperature variations. Temperature variation and the length of the pipe are the two variables that will determine linear expansion.

The equation to calculate the length changes is as follows:


α Thermal expansion for MultiSkin pipesThermal expansion for BetaSkin pipes

0.025 mm/m/°K0.025 mm/m/°K

L Pipe lenght m

Δθ Temperature difference °K

∆L= α x L x Δθ

Tables and graphs 3 and 4 show the expansion of the MultiSkin and BetaSkin pipes depending on the length of the pipe and increase in temperature.

Example: A network with a length of 24 m consisting of multilayer pipes with a diameter of 20 mm is subjected to a temperature difference of 50°C. When using the equation for calculating expansion, the result is:

Δl = α x L x ΔθΔl = 0.025 x 24 x 50 = 30 mm

We would get the same result using table 3 or graph 3 (see red marks next page). For pipes longer than 10 m, add the different results for linear expansion together:

12.5 mm (10 m) + 12.5 mm (10 m) + 5 mm (4 m) = 30 mm (24 m)

3.3. Pressure drop3.3.1. Linear pressure dropAll liquid loses energy when it flows through a pipe, as a result of friction between the liquid and the walls of the pipe. Continuous and local pressure drops must be considered separately. Continuous pressure drops are mainly caused by the resistance to flow in straight pipe sections, which is itself mainly caused by friction between the fluid and the pipe wall. Local pressure drops are caused by resistance to flow due to turbulence, for instance, if the inner diameter of a pipe changes, at pipe branches, elbows, etc.

Natural gas application (12°C)Just like water, gas will also lose energy due to friction with the wall of the pipe. Correct pipe calculations can be made using the pressure loss diagram for gas. According to the Dutch standard NEN 1078, the piping must be designed so that its pressure loss is no more than the difference between the working pressure and the minimum necessary consumption pressure according to the appliance manufacturer. For a household gas installation, this means that the total pressure loss from the outlet of the gas meter to the appliance may be 250 Pa (2.5 mbar).

Example:Diagram: With a 16x2 diameter elbow joint, if the flow is equal to x=900 l/h, the corresponding pressure drop is y=0.3 bar (300 mbar) per metre.

Kv value: the quantity of water in m3 that flows through the fitting creating pressure drop of 1 bar per metre.

∆P Pressure drops mbar

Kv Kv value (see table below each figure) m3/h

Q Flow m3/h

∆P= 1000(Q/Kv)2

The calculation shows: ∆P= 1000(0.9/1.68)2

∆P= 287 mbar

With a 16x2 elbow joint, if the flow rate is 900 l/h or 0.9 m3/h (see table of equivalents on page 57) and the Kv value is 1.68, pressure drop is 287 mbar per metre, or 0.3 bar per metre.

With a 16x2 elbow joint, if the flow rate is 900 l/h and the Zeta value ( ζ ) is 1.8, pressure drop is 28800 Pa per metre, or 0.3 bar per metre.

Calculation of velocity:

With a 16x2 elbow (i.e. an inner diameter of 7,5 mm or an inner radius of 0,00375 m), if flow is 900 l/h (i.e. 0.00025 m3/s), then flow velocity is 5.7m/s).

1.2.3. Visu-Control® technologyWith a plastic ring (in polyamide) attached to each side of the fittings, the patented Visu-Control® technology offers a visual and tactile crimping indicator.

} Visual verification: during pressing, the pressure of the jaws deforms the plastic ring. The visual indicator consists of two clearly identifiable lugs.

} Tactile control: the recyclable ring is fixed in place during transport and handling, and is easily removed after pressing.

The Visu-Control® ring for each application has a dedicated colour, to avoid any errors:

1.2.4. Patented o-ringThe standard fittings for water and heating are provided with EPDM O-rings. The type of O-ring to be used depends on the application and the medium. For this reason, the gas press fittings are provided with HNBR O-rings. For special applications, such as oil-containing substances or high temperatures, the FPM O-ring should be used. Copper press fittings are supplied with an O-ring designed to indicate if a fitting is not pressed. When the fitting is not crimped, the O-ring will leak water.

Functioning of patented O-ring with copper pipes and fittingsThe patented O-ring is designed using a leak path within the O-ring itself.

Small grooves have been placed at three strategic points on the surface of the O-ring.

This means that water will flow through these grooves when the fitting is not pressed. When the O-ring is pressed, the rubber blocks the grooves. This creates a fully water- and air-tight connection.

1.2.5. Crimping ToolsPress tools consist of a crimping machine and the corresponding jaws, inserts, adapters and chains. The pressing machine can be used with battery or mains power, depending on the model.

For each pipe diameter, the correct components should be used for a perfectly tight connection (see table below).

COMAP’s rangeCCOMAP offers a range of crimping tools designed to ensure reliability and simplicity for professionals. Novopress ACO 102, ACO 202 and ECO301 and Klauke MAP2L and UAPL3L tools allow crimping of all diameters of copper, PEX, multilayer, carbon steel and stainless steel pipe. The system of inserts and jaw allows open tools to be used with Multisertissage®, simply by changing the inserts (rather than the large and heavy jaws).

2. IMPLEMENTATION2.1. Planning2.1.1. Embedding*

For aesthetic and practical reasons, pipes are rarely installed uncovered in modern homes other than in auxiliary rooms,such as cellars and garages. Embedding pipes in walls or under floors requires several precautionary measures depicted schematically in figures 1, 2 and 3. The following items can be embedded:

} SudoPress Copper, Tectite Sprint and Xpress Copper, without corrosion protection1

} SudoPress Stainless and XPress Stainless, without corrosion protection²

} SudoPress in carbon steel, Tectite Carbon and XPress in carbon steel, coated with polypropylene (fittings must have corrosion protection)

Because they are detachable, Tectite Classic fittings may not be embedded.

1 For gas applications, fittings must not be installed in structural elements (e.g.: embedded in a wall or plate). 2 If building materials contain chloride, pipes must be protected accordingly.

Important: embedded water pipes (e.g. in walls or floors) must always be coated to separate the pipe and the building structure (e.g. soundproofing).

Figure 1 shows a cross section of a pipe embedded in a wall.

Installation in brickwork

Pipes and fittings must be wrapped in flexible insulation designed to completely insulate the pipes in the building and eliminate any direct contact (mainly in areas near to tee connectors and elbows). The insulation materials prescribed by DIN 1988 provide an effective solution for this purpose. They also provide thermal insulation.

Installation under a plate

For pipes embedded in the ground (including sprung floors), make sure the horizontal segments are covered by flexible insulation. Also ensure that an adequate elastic duct is installed where the pipe exits the floor, preventing any contact with cement subsequent to any modifications to tube diameter (see figure 2).

Soundproofing is important, mainly for pipes under a plate. Refer to DIN 4109 in this case.

Installation across a slab or wall

With pipes crossing slabs or walls, use flexible insulation with adequate clearance (figure 3).

* Does not apply to gas installations. For gas installations, refer to local regulations.

2.1.4. Thermal expansion compensationNote: To calculate thermal expansion, see chapter 3.2 on thermal expansion.

Z- and L- shaped expansion compensation componentsIn case of significant expansion, compensation must be calculated and the results applied to the installation setup. This will avoid tension within the system, which could deform and damage the connections. The formula used to calculate expansion compensation (in mm) is as follows:

Example: A network with a length of 24 m consisting of copper pipes with a diameter of 22 mm subject to a temperature difference of 50°C. We need to calculate the length needed to compensate for this expansion, ∆L (according to chapter 3.2 on linear expansion).

∆L= α x L x ΔT = 0.0165 (copper coefficient) x 24m x 50°K = 19.8 mm

Linear expansion is equal to 19.8 mm.

Using graph 1 or table 1, we obtain approximately 1280 mm (see red marks).

Analytical calculation: Bd = 61 x √(22 x19.8)

Bd = 1273 mm

U-shaped equalizerIn case of significant expansion, U-shaped compensating loops will need to be fitted and compensation calculated for these devices. This will avoid tension within the system, which could deform and damage the connections. The formula used to calculate expansion compensation (in mm) is as follows:

2.1.6. Attaching pipesAs can be seen in figures 5, 6 and 7, correct expansion compensation also depends on the placement of fixing devices such as saddles and clips.

Attachment points must be on straight pipe segments. Attachments cannot be located on fittings. Never use sliding fixtures as attachments near to a pipe connection. Position saddles so that they are not used as fixed supports.

For straight segments of pipe without expansion compensation, use only one sliding fixture to prevent deformation. Position this fixture as close to the middle of the straight pipe segment as possible: in this way, any expansion will be distributed in both directions and the length required to compensate expansion will be halved.

2.2. InstallationBending It may be necessary to bend a pipe for installation purposes. Manual, hydraulic or electric bending tools exist for this purpose The manufacturer will determine the most suitable tools.

Refer to DIN EN 1057 and DVGW - GW 392 for copper pipes. These standards define bend radii.

2.2.1. Press-fitting installation

Cut the pipe to lengthAfter measuring, the pipes can be cut to length using a pipe cutter, a fine-toothed handsaw or a mechanical saw with electrical motor suitable for the pipe material. Always completely cut the pipe. Never cut it only partially, because this leads to corrosion.

Do not use an oil-cooled saw, abrasive wheel or blowtorch.

With SudoPress and XPress carbon steel pipes with polypropylene coating or copper pipes in ducts, it is essential to remove the pipe’s synthetic coating before assembling and pressing press fittings.

Deburring pipes The pipe ends must be carefully deburred inside and out after being cut to length. This is in order to avoid damage to the o-ring when inserting the pipe into the press fitting.

Deburring the inside of pipes prevents pitting and corrosion.

Deburring inside and outside can either be carried out using a hand deburrer suitable for the material or an electrical pipe deburrer. Burrs sticking to the pipe must be removed.


97

MarkingThe necessary insertion depth must be marked on the pipe or the press fitting (for fittings with pipe ends) in order to guarantee a safe and clean crimped fitting. The marking on the pipe must remain visible (close to the fitting) after the connection is pressed to identify any movement before or after crimping.

Note: Before assembly, the fitting must be checked to ensure the correct positioning and presence of the O-rings. The pipe, fitting and O-ring should be examined for for-eign material (e.g. dirt, burrs), which must be removed if present.

Assembly of fittings and pipesInsert the pipe into the press fitting up to the marked insertion depth while rotating slightly and pushing in an axial direction at the same time. The marking for the insertion depth must still be visible. In case of fittings without a stop, the fittings should be inserted at least as far as the marked insertion depth. The pipe must not be inserted into the press fitting in a rough or careless manner, because this may result in damage to the O-ring.

PressingBefore pressing, the press jaws and slings must be checked for contaminants. It is necessary to make sure that press jaws are not seriously worn, because this may affect pressing. Any impurities found must be removed. Furthermore, the press machine must be in good working condition and the operating and maintenance instructions provided by the manufacture must be complied with.

Use the correct pressing jaws and chains for the chosen fittings.

The notch of the press tool must enclose the press fitting groove to ensure safe crimping.

Once the pressing process is begun, it must not be interrupted.

Visu-Control® technologyInstallers can check crimping both visually and by touch thanks to Visu-Control® technology (plastic rings at the end of fittings).

2.2.2. Installation of Tectite push fittings

ASSEMBLY

1 Choose the pipe and fitting with the desired diameter for the installation. Make sure they have no damage or imperfections. Do not use additional lubricants or sealing compounds. Cut the pipe cleanly at a 90° angle.

2 De-burr and chamfer the pipe on the inside and outside, so as not to damage or displace the O-ring inside the fitting. Use a calibrator if the pipe is deformed.

3 For a perfect connection, insert the pipe completely into the fitting until it touches the stop. Mark the insertion depth on the pipe (see the table of insertion depths).

4 For PB, PEX or multilayer pipes, make sure support liners are inserted into the pipe.

5 Inspect the fitting and verify that the O-ring or grab ring have not been contaminated. Place the pipe next to the opening of the fitting.

6 Push the pipe firmly with a slight rotating motion. A distinct click lets you know that the pipe has touched the stop.

7 Make sure that the insertion depth marking is even with the mouth of the fitting, and pull firmly on the pipe to ensure the connection with the fitting is secure.

REMOVAL

8 Tectite Classic (< 35 mm) Place the disconnecting tool around the fitting. The side of the tool that is printed with the Tectite logo must be placed around the pipe, and the other side around the fitting body. Squeeze the tool with one hand until the pressure of the fitting on the pipe is released. With the other hand, pull the pipe while turning it, using your thumb as a lever.

9 Tectite Classic (< 35 mm) The plastic disconnecting clip may be used for occasional disconnection.

10 Tectite Classic (> 28 mm) Place the forks of the disconnecting tool on the inside edges of the fitting. Turn the fitting’s end cap anti-clockwise until it is in the demountable position. Then, pull the pipe to disconnect it from the fitting.

3. ADVANCED TECHNICAL FIGURES3.1. Metal combinationsSudoPress and Tectite brass, copper or bronze fittings may be combined with other metals.

However, there are several rules to follow when doing this.

Connecting to carbon steel or less noble fittings or components can lead to contact corrosion. This can be avoided by using synthetic or No-ferrous fittings or spacers with a minimum length of 50 mm (DIN 1988, part 7). Refer to chapter 3.5 for more information on corrosion.

The following table shows possible combinations.

We recommend using bronze or brass fittings to connect copper with either stainless or carbon steel, or to connect carbon steel to stainless steel, in order to limit the dielectric effect. In gas systems, different metals must not be combined.

3.2. Thermal ExpansionNote: To calculate thermal expansion, refer to chapter 2.1.4. Compensating for thermal expansion.

All metals expand when heated and contract when cooled. Length variation due to temperature fluctuation must therefore be taken into account. Temperature variation and the length of the pipe are the two variables that will determine linear expansion.

The equation to calculate linear expansion is as follows:

∆L = α x L x ΔT


α Thermal expansion coefficient for copper pipesThermal expansion coefficient for stainless steel pipes 1.4401

Thermal expansion coefficient for stainless steel pipes 1.4521/1.4520 Thermal expansion coefficient for carbon steel pipes

0.0165 mm/m/°K0.0160 mm/m/°K0.0104 mm/m/°K0.0108 mm/m/°K

L Pipe lenght m

ΔT Temperature difference °K

Tables and graphs 5, 6, 7 and 8 show the expansion of copper pipes according to the length of the pipe and the increase in temperature.


102

Example:A 24 m network of 22 mm diameter copper pipes is subjected to a temperature difference of 50°C. When using the equation for calculating expansion, the result is:

l = 24 x 0.0165 x 50 = 19.8 mmThe same result can be obtained using graph 5 or table 5.

For pipes longer than 10 m, add the linear expansion values together:

8.25 mm (10 m) + 8.25 mm (10 m) + 3.30 mm (4 m) = 19.8 mm (24 m)

3.3. Pressure LossAny fluid flowing through a piping system faces resistance to flow, which leads to pressure drops in the system. Continuous and local pressure drops must be considered separately. Continuous pressure drops are mainly caused by the resistance to flow in straight pipe sections, which is itself mainly caused by friction between the fluid and the pipe wall.

Local pressure drops are caused by resistance to flow due to turbulence, for instance, if the inner diameter of a pipe changes, at pipe branches, elbows, etc.

3.3.1. Linear pressure dropWith graph 10 and table 10, it is possible to determine the unit pressure drop R (mbar/m) and the flow velocity V (m/s) for a given water flow (m3/h or l/s).

The values shown in graph 10 and table 10 are calculated for a water temperature of 60°C. To determine the value of the pressure drop for a water temperature other than 60°C, use graph 9 or table 9 to apply a correction factor.

Example:

Calculate the linear pressure drop of a network with a length of 24 m consisting of copper pipes with a diameter of 18 mm. Water flow is 0.2 l/s (720 l/h) and mean temperature is 40°C. According to graph 10 or table 10, the pressure drop is equal to 7 mbar/m (for a water temperature of 60°C).

To correct for a water temperature of 40°C, use the following formula:

For a temperature of 40°C, pressure will drop by 7.33 mbar/m in this network, i.e. 175 mbar for 24 meters.

3.3.3. Pressure drop equivalent lengthsThis method gives the length of a straight pipe segment of the same diameter that would have the same pressure drop as a given fitting. To use this calculation method, all equivalent length values for each fitting must be added to the actual length of the system. In this way, we get the total pressure drop of all the fittings in the network.

This method is not as precise as the direct method, but the calculation is quicker.

1.2.4. Patented o-ringThe standard fittings for water and central heating are provided with EPDM O-rings.

The type of O-ring to be used depends on the application and the medium. For this reason, the gas press fittings are provided with HNBR O-rings. For special applications, such as oil-containing substances or high temperatures, the FPM O-ring should be used. Copper press fittings are supplied with an O-ring designed to indicate if a fitting is not pressed. When the fitting is not pressed, the O-ring will leak water.

Function of the patented O-ring with stainless and carbon steel systems.The SkinPress patented O-ring is designed using a leak path within the O-ring itself.

Small grooves have been created at strategic points on the surface of the o-ring.

This means that water will flow through these grooves when the fitting is not pressed. When the connection is pressed, the material blocks the grooves and guarantees total air- and watertightness.

Functioning of patented O-ring with Xpress pipes and fittingsXpress fittings in stainless and carbon steel have a patented O-ring included. With this O-ring, No-pressed connections leak during the pressure test. Incompletely pressed connections are easily spotted. Once pressed, the system is completely air- and water-tight.

The patented O-ring is designed using a leak path within the O-ring itself. To this end, material has been added to the O-ring. The result is an exceptionally robust O-ring, with no weaknesses.

Small grooves have been created at strategic points on the surface of the O-ring. This means there is a slight bulge on the O-ring’s surface, and so water will flow through these grooves when the fitting is not pressed. An increase in pressure causes increased leaking. During pressing, the O-ring is deformed, forcing the rubber in the raised surfaces to fill the grooves, creating a completely water- and air-tight connection.

1.3.4. Crimping ToolsPress tools consist of a crimping machine and the corresponding jaws, inserts, adapters and chains. The pressing machine can be used with battery or mains power, depending on the model. For each pipe diameter, the correct components should be used for a perfectly tight connection (see table below).

1.5.2. SudoPress and XPress carbon steel pipesSudoPress carbon steel pipes are thin-walled precision pipes. SudoPress carbon steel pipes are protected against external corrosion by a layer of zinc passivated with chrome. The zinc layer is applied hot, which results in good adhesion between the zinc layer and the pipes.

This chapter provides complete technical data, mainly in relation to the manufacture of SudoPress and XPress carbon steel pipes.

Heat insulation

The following regulations apply to the insulation of SudoPress and XPress carbon steel pipe systems:

} Cold water pipes must be protected against condensation and overheating in accordance with DIN 1988, Part 2.

} Hot water pipes must be insulated to prevent heat loss in accordance with law regarding energy conservation (such as the German EnEV).

Fire characteristics

SudoPress and XPress stainless steel pipes are considered as incombustible pipes, corresponding with European class A building materials – EN 13501-1.

XPress carbon steel pipes with polypropylene coating are considered as combustible pipes, corresponding with European class B2 building materials – EN 13501-1, i.e. burning without dripping. Metallic pipes with a synthetic coating up to a thickness of 2 mm are considered an incombustible product in accordance with European building regulations.

SudoPress carbon steel pipeSudoPress carbon steel pipes are thin-walled precision pipes manufactured in accordance with EN 10305-3 (previously DIN 2394/ NEN 1982) from a special kind of steel that has a very low carbon content. The resulting product is very easy to bend. The absence of leaks is also checked, in accordance with EN 10246-1, so that all pipes will be guaranteed leak free.

XPress carbon steel pipes with polypropylene coatingXPress carbon steel pipes with polypropylene coating are used for the same applications and have the same technical characteristics as XPress carbon steel pipes (polypropylene coated pipes are marked “Galvanized - Polypropylene coated”) and are coated with a layer of polypropylene (PP) for protection against external corrosion.

PP has a smooth surface and is highly resistant to tearing and impact. For safe crimping, it is essential to remove the polypropylene coating with a stripping unit along a length equivalent to the appropriate insertion depth. To guarantee a reliable press connection, it is necessary to maintain the insertion depth.

2. IMPLEMENTATION2.1. Planning2.1.1. Embedding*For aesthetic and practical reasons, pipes are rarely installed uncovered in modern homes other than in auxiliary rooms, such as cellars and garages. Embedding pipes in walls or under floors requires several precautionary measures depicted schematically in figures 1 and 2. The following items can be embedded:

} SudoPress Copper, Tectite Sprint and Xpress Copper, without corrosion protection1

} SudoPress Stainless and XPress Stainless, without corrosion protection2

} SudoPress in carbon steel, Tectite Carbon and XPress in carbon steel, coated with polypropylene (fittings must have corrosion protection)

Because they are detachable, Tectite Classic fittings may not be embedded. 1 For gas systems, fittings must not be installed in structural elements (e.g.: embedded in a wall or plate).² If building materials contain chloride, pipes must be protected accordingly.

Important: embedded water pipes (e.g. in the walls or floors) must always be coated to separate the pipe and the building structure (e.g. soundproofing).

Figure 1 shows a cross section of a pipe embedded in a wall.

Installation in brickwork

Pipes and fittings must be wrapped in flexible insulation designed to completely insulate the pipes in the building and eliminate any direct contact (mainly in areas near to tee connectors and elbows). The insulation materials prescribed by DIN 1988 provide an effective solution for this purpose and also provide heat insulation.

Installation under a plate

Likewise, for pipes embedded in floors, including floating parquet, make sure that horizontal sections are insulated with flexible insulation. Also ensure that an adequate elastic duct is installed where the pipe exits the floor, preventing any contact with cement subsequent to any modifications to tube diameter (see figure 2).

Soundproofing is important, mainly for pipes under a plate. Refer to DIN 4109 in this case.

Installation across a slab or wall

With pipes crossing slabs or walls, use flexible insulation with adequate clearance (figure 3).

* Does not apply to gas installations. For gas installations, refer to local regulations.

2.1.4. Thermal expansion compensationNote: To calculate thermal expansion, see chapter 3.2 on thermal expansion.

Z- and L- shaped expansion compensation components In case of significant expansion, expansion compensation must be calculated and the results applied to the installation setup. This will avoid tension within the system, which could deform and damage the connections. The formula used to calculate expansion compensation (in mm) is as follows:


Bd Expansion compensation length mm

k1 Constant for copper pipes Constant for carbon and stainless steel pipes

Example: A distribution network with a length of 24 m, consisting of 22 mm diameter copper pipes, subject to a temperature difference of 50°C.


∆L= α x L x ΔT = 0.0160 (stainless steel coefficient) x 24m x 50°K = 19.2 mm

The network’s linear expansion is equal to 19.2 mm.

2.1.6. Attaching pipesAs shown by figures 5, 6 and 7, the satisfactory compensation of expansion also depends on the methods used to attach pipes, such as sliding brackets and sliding.

Attachment points must be on straight pipe segments. Attachments cannot be located on fittings. Never use sliding fixtures as attachments near to a pipe connection. Make sure that sliding brackets are positioned such that they do not behave as a fixed attachment.

When straight segments of pipe exist without expansion compensation, only use one sliding fixture to prevent any deformation. Position this fixture as close to the middle of the straight pipe segment as possible: in this way, any expansion will be distributed in both directions and the length required to compensate expansion will be halved.

2.2. InstallationBending It may be necessary to bend a pipe for installation purposes. Manual, hydraulic or electric bending tools exist for this purpose. The manufacturer will determine which tools are most suitable.

SudoPress and XPress stainless steel and carbon steel pipes must be bent cold, in accordance with DIN EN 1057.

SudoPress and XPress pipes may not be bent hot, due to the risk of corrosion.

Minimum bend radius (rmin) is as follows:

} Stainless steel pipe (Ø 15-28 mm): rmin = 3.5 x d

} Carbon steel pipe (Ø 12-28 mm): rmin = 3.5 x d

Do not use a smaller bend radius.

Refer to DIN EN 1057 and DVGW - GW 392 for copper pipes. These standards define bend radii.

2.2.1. Press-fitting installation

Cut the pipe to lengthAfter measuring, pipes can be cut to the required length using a pipe cutter, a fine-toothed handsaw or a mechanical saw with an electric motor suitable for the pipe material. The pipe should always be cut completely. Cutting the pipe only partially can cause corrosion.

Do not use oil-cooled saws, abrasive wheels or a blow torch.

With SudoPress and XPress carbon steel pipes with polypropylene coating or copper pipes in ducts, it is essential to remove the pipe’s synthetic coating before assembling and pressing press fittings.

Deburring pipes The pipe ends must be carefully deburred inside and out after being cut to length. This is in order to avoid damage to the o-ring when inserting the pipe into the press fitting.

Deburring the inside of pipes prevents pitting and corrosion.

Deburring in- and outside can either be carried out using a hand deburrer suitable for the material or an electrical pipe deburrer. Burrs sticking to the pipe must be removed.


149

MarkingThe necessary insertion depth must be marked on the pipe or the press fitting (for fittings with pipe ends) in order to guarantee a safe and clean pressed fitting. The marking on the pipe must remain visible (close to the fitting) after the connection is pressed to identify any movement before or after crimping.

Note: Before assembly, the fitting must be checked to en-sure that the O-rings are correctly in place. The pipe, fitting and O-ring should be examined for foreign material (e.g. dirt or shavings), which must be removed if present.

Assembly of fittings and pipesInsert the pipe into the press fitting up to the marked insertion depth while rotating slightly and pushing in an axial direction at the same time. The marking for the insertion depth must still be visible.

In case of fittings without a stop, the fittings must be inserted at least as far as the marked insertion depth. The pipe must not be inserted into the press fitting in a rough or careless manner, because this may result in damage to the O-ring.

CrimpingBefore pressing, press jaws and chains must be checked for contaminants. It is necessary to make sure that press jaws are not seriously worn, because this may affect pressing. Any impurities found must be removed. Furthermore, the press machine must be in good working condition and the operating and maintenance instructions provided by the manufacture must be complied with.

Also make sure that you use the correct press jaws and units and that these parts correspond to the fittings used.

The notch of the press tool must enclose the press fitting groove to ensure safe crimping. After starting crimping, always complete the crimping cycle. The cycle must not be interrupted under any circumstances.

Visu-Control® technology (SudoPress fittings)Installers can check crimping both visually and by touch thanks to Visu-Control® technology (plastic rings at the end of fittings).

2.2.2. Installation of Tectite push fittingsCutting

Choose the pipe and fitting with the desired diameter for the installation. Make sure they have no damage or imperfections. Do not use additional lubicants or sealing compounds. Cut the pipe cleanly at a 90° angle.

Chamfering and deburring

When chamfering has been done, get rid of burrs and sharp edges on the exterior and interior surfaces of the pipe, using a deburring tool. Wipe down the pipe end to remove filings and debris.

If this is not correctly done, the O-ring may be damaged and the fitting will be less efficient.

Marking

Mark insertion depth on the pipe (see table of insertion depths).

Connect

Place the pipe next to the opening of the fitting. Push the pipe firmly with a slight rotating motion. A distinct click lets you know that the pipe has touched the stop. Make sure that the insertion depth marking is even with the mouth of the fitting, and pull firmly on the pipe to ensure the connection with the fitting is secure. For a perfect connection, insert the pipe completely into the fitting until it touches the stop.

3. ADVANCED TECHNICAL FIGURES3.1. Metal combinationsSudoPress and XPress fittings in stainless steel may be used with components made of other metals. But there are several rules to follow when doing this.

Connecting to carbon steel or less noble fittings or components can lead to contact corrosion. This can be avoided by using synthetic or No-ferrous fittings or spacers with a minimum length of 50 mm (DIN 1988, part 7). Refer to chapter 3.5, Corrosion, for more information on corrosion.

The following table shows possible combinations.

We recommend using bronze or brass fittings to connect copper with either stainless or carbon steel, or to connect carbon steel to stainless steel, in order to limit the dielectric effect. In gas systems, different metals must not be combined.

3.2. Thermal ExpansionNote: To calculate thermal expansion, refer to chapter 2.1.4. Compensating for thermal expansion.

All metals expand when heated and contract when cooled. Length variation due to temperature fluctuation must therefore be taken into account. These are the two variables that will determine linear expansion.

The equation to calculate linear expansion is as follows:

∆L = α x L x ΔT

∆L Sliding point mm

α Thermal expansion coefficient for copper pipesThermal expansion coefficient for stainless steel pipes 1.4401

Thermal expansion coefficient for stainless steel pipes 1.4521/1.4520 Thermal expansion coefficient for carbon steel pipes

0.0165 mm/m/°K0.0160 mm/m/°K0.0104 mm/m/°K0.0108 mm/m/°K

L Pipe length m

ΔT Temperature difference °K

Tables and graphs 3, 4 and 5 show the expansion of stainless steel and carbon steel pipes corresponding to the length of the pipe and increase in temperature.

154


Example:A 24 m network of 22 mm diameter stainless-steel pipes is subjected to a temperature difference of 50°C. When using the equation for calculating expansion, the result is:

l = 24 x .0160 x 50 = 19.2 mmThe same result can be obtained using graph 5 or table 5.

For pipes longer than 10 m, add the linear expansion values together:

8 mm (10 m) + 8 mm (10 m) + 3.2 mm (4 m) = 19.2 mm (24 m)

3.3. Pressure LossAny fluid flowing through a piping system faces resistance to flow, which leads to pressure drops in the system. Continuous and local pressure drops must be considered separately. Continuous pressure drops are mainly caused by resistance to flow in straight pipe sections, which is itself mainly caused by friction between the fluid and the pipe wall.

Local pressure drops are caused by resistance to flow due to turbulence, for instance, if the inner diameter of a pipe changes, at pipe branches, elbows, etc.

3.3.1. Linear pressure dropWith graph 10 and table 10, it is possible to determine the unit pressure drop R (mbar/m) and the flow velocity V (m/s) for a given water flow (m3/h or l/s).

The values shown in graph 10 and table 10 are calculated for a water temperature of 60°C. To determine the value of the pressure drop for a water temperature other than 60°C, use graph 9 or table 9 to apply a correction factor.

Example:

Calculate the linear pressure drop of a network with a length of 24 m consisting of stainless steel pipes with a diameter of 18 mm. The water is flowing at 0.2 l/s (720 l/h) and its mean temperature is 40°C. According to graph 10 or table 10, the pressure drop is equal to 7.3 mbar/m (for a water temperature of 60°C).

To correct for a water temperature of 40°C, use the following formula:

T°C Kc10 1.03

3.3.3. Pressure drop equivalent lengthsThis method gives the length of a straight pipe segment of the same diameter that would have the same pressure drop as a given fitting. To use this calculation method, all equivalent length values for each fitting must be added to the actual length of the system. In this way, we get the total pressure drop of all the fittings in the network.

This method is not as precise as the direct method, but the calculation is quicker.

1. PRESSURE TESTAfter installation, pipes are checked to ensure that there are no leaks. With drinking water and heating systems, pressure tests can be carried out with water, air or inert gases. The fluid used and the results of the pressure tests must be recorded in a «pressure test report».

Important: Piping systems must always be pressure tested before sealing, insulation, painting and installation. Pressure tests must always be performed in accordance with local regulations.

Note: Because of corrosion risk, ensure that no water remains in the pipes after testing carbon-steel systems with water, unless the system will be used immediately.

1.1. Pressure tests for drinking and sanitary water systemsPressure tests with waterImportant: On drinking water pipes that have already been installed, pressure tests using water are performed in accordance with the ZVSHK/BHKS technical data sheets. For pressure tests with water, the water used must be potable (free of oil and other impurities) in order to avoid contaminating the pipe system. After being filled with pure water, the pipe must be suitably bled.

} The installer must check that heating pipes are sealed before these are encased or covered with cement, plaster or other materials.

} The pressure gauge used must be capable of measuring a pressure difference of 0.1 bar.

} The pressure gauge must be fitted at the lowest point of the installation.

Three tests must be performed:

1/ Leak testingThis test is necessary only if fittings with COMAP patented O-rings («leaking» rings) have been installed in the system.

Testing at a pressure between 1 and 5 bar is recommended. Because of the COMAP patented O-ring, this first pressure test will show if any pressed connections are incomplete.

2/ Pressure testing (preliminary)

} Pressure testing is performed at a pressure about 1.5 times greater than maximum operating pressure.

} For 30 minutes, the pipe system must be placed under pressure 1.5 times greater than maximum operating pressure. Then, after a 10-minute interval, the system must once more be placed under pressure 1.5 times greater than maximum operating pressure for 30 minutes.

} Another 30-minute test follows, during which pressure must not drop by more than 0.6 bar (0.1 bar per 5 minutes) and the installation must remain watertight.

3/ Pressure testing (main)

} The main test must take place immediately after the introductory test.

} This test must last for 2 hours.

} The pressure measured in the introductory test must not have dropped by more than 0.2 bar after these 2 hours.

} The installation must remain 100% watertight.

Pressure tests with airImportant: Pressure testing with air or inert gases can be carried out in accordance with the ZVSHK/BHKS technical data sheets “Pressure tests with air or inert gases”.

For safety reasons, maximum test pressure is set to 3 bar. This limit also applies for gas pipes.

Implementation

1.2. Pressure tests for heating and cooling systems*

Important: As a rule, pressure tests on pipes are carried out with water, in accordance with DIN-EN DIN-VOB 18380.

} The installer must check that heating pipes are sealed before these are encased or covered with cement, plaster or other materials.


} The pressure gauge must be fitted at the lowest point of the installation.

} The heating installation must be put under water pressure and de-aerated (and, if necessary protected against frost).

} The heating pipe must undergo a pressure test at a pressure 1.3 times greater than the total pressure of the installation (static pressure), with at least 1 bar over-pressure at each point of the installation.

} Immediately after the cold water pressure test, the water must be heated up to the highest hot water temperature taken as the basis for the calculation, in order to determine if the system remains sealed at high temperatures.

} The pressure test must be 24 hours in duration.

} The pressure must not drop by more than 0.2 bar.

} The installation must remain watertight.

} Once the water has cooled down, check whether all pipes and fittings have remained watertight.

} Pressure tests must be appropriately recorded.

1.3. Pressure tests for gas systemsGas systems must be tested in accordance with EN 1775 and local technical regulations.

1.4. Pressure tests on floor heating installationsImportant: pressure tests are carried out with water, in accordance with DIN 4725.

} Before covering the heating circuit, check its water-tightness (perform water pressure test).


} All pipes must first be pressurised and de-aerated.

} Water pressure must be measured just before and just after the covering is placed.

} The test pressure must be 1.3 times greater than the operating pressure.

} COMAP recommends testing the pipes with pressure of 6 bar, over a period of 24 hours.

} Make sure the shut-off valves for the floor heating manifold are fully closed so that the test pressure remains isolated from the rest of the installation.

} The pressure must not drop by more than 0.2 bar and the installation must remain watertight.

} When putting the floor covering in place, the operating pressure must be reduced to the maximum permissible operating pressure.

} Suitable measures are to be taken in case of frost (use anti-frost products or heat the building).

} Once the heating system is no longer at risk of freezing, the anti-freeze products must be fully removed from the pipes. The installation must be flushed with clean water at least three times as anti-frost products may cause corrosion on the metal parts of the floor heating system.

*Pressure test protocols are available on pages 168, 169 and 170.

2. FLUSHING THE NETWORKAll pipes must be flushed thoroughly before initial use to ensure that foreign matter and substances are removed from inside the pipe and that hygiene problems and corrosion damage are prevented as far as possible.

The drinking water pipe must be flushed as soon as possible after installation and after pressure tests. Cold and hot water pipes will be flushed separately, intermittently and under pressure with an air-water mixture (DIN 1988, part 2).

Water of near-drinking water quality must be used to flush pipes to avoid any possible contamination of the pipes.

3. LEGIONNAIRE’S DISEASE PREVENTIONLegionella bacteria develop in all soft water, particularly in tap water, but it does not present any danger except in certain highly specific circumstances. These depend mainly on the design and maintenance of the system, not on the type of pipe used in the system. The temperature of the water plays an important part. The bacteria are harmless below 25°C. Temperatures of 60°C create risk. In addition, running water is harmful to these bacteria.

The danger occurs in water with a temperature between 25°C and 50°C that atomised. When circumstances are conducive to the bacteria’s growth (old pipes, build-up of corrosion), outside the zones where the bacteria is dormant or cannot survive, proliferation becomes a concern.

The COMAP pipe is corrosion-resistant thanks to the smooth interior wall of the cross-linked inner pipe. Therefore, the remaining measures to take are:

} Set the temperature of the boiler so that the supply pipe stays at a temperature of least 60°C. Set the return to 50°C and have the mixing take place as near as possible to the sanitary branch point (e.g. shower).

} Regularly flush all pipes abundantly with hot water, especially after a long absence.

} Empty unused sections of pipe.

} Avoid stagnant water.

4. CORROSIONVarious types of corrosion exist: chemical corrosion, electrochemical corrosion, internal and external local corrosion, stray current corrosion, etc. In general, all these kinds of corrosion have very specific chemical or mechanical causes. The following section provides some simple hints that will help to prevent these problems from arising.

Electrochemical corrosion

For electrochemical corrosion to take place, the following conditions must be met:

- Different electrochemical potential for the two parts

- A conductive fluid (electrolyte), e.g. water, must be present,

- Oxygen, O2, must be present.

Heating systems and water supply systems should be considered separately. No significant amounts of oxygen are present in heating systems if they are properly installed and operated, therefore, little corrosion will occur. On the other hand, the oxygen content of drinking water systems is very high, near to saturation level.

It is of primary importance for less noble metals to be installed upstream and for nobler metals to be installed downstream. For example, it is possible to install branches with stainless steel pipe onto a system composed of carbon steel pipes. Non-ferrous metal or synthetic fittings can be used (see DIN 1988). Another important factor is the ratio between the surface of the noble metal and that of the less noble metal. The higher this ratio, the greater the corrosion rate.

For this reason, the use of extensions or fittings made from carbon steel should be avoided as much as possible, and fittings in stainless steel, brass or bronze should be used instead.

Stray currents

Corrosion from stray currents rarely occurs in practice and is immediately recognisable as it starts on the outside of the pipe with a cone-shaped crater directed towards the inside of the pipe. Stray current corrosion requires a direct current that turns the metal into an anode. Any current that, despite isolation measures, penetrates into the ground and spreads into other neighbouring metal structures, such as a water supply system, will pass through a very precise length of the system before returning to the ground. In order to penetrate the piping system, the earth current must find an entry point where the normal protective coating of the pipe or fitting is damaged or missing.

For this reason, metal pipes must be earthed (see EU regulations). Direct current systems are not generally intended for domestic use, for which no real problems arise with alternating current. Studies carried out over many years have shown that the problems caused by stray currents only occur sporadically and do not depend on the type of metal.

CopperInternal corrosion

The physical and chemical properties of drinking water can be affected by copper in the event of internal corrosion. Depending on its composition, even drinking water can cause corrosion. Copper is not corroded by water containing glycol or de-mineralized or distilled water.

External corrosion

Copper is highly resistant to corrosion. Corrosion protection is therefore not required with copper.


173

Stainless steelInternal corrosion

SudoPress stainless steel pipes and press fittings are completely passive when in contact with drinking water and therefore not at risk from corrosion. Drinking water is considered as water with properties conforming to current regulations on physical-chemical tolerance intervals.

Water to which 1.34 mg/l of chlorine is added for disinfection purposes poses no dangers or problems for pipes and fittings. The SudoPress stainless steel system can also be used for all types of domestic water treatment (e.g. for water hardeners).

The SudoPress stainless steel system is not corroded by water containing glycol, de-mineralized water or distilled water. Hygiene problems regarding heavy metal contamination do not occur when using SudoPress stainless steel components. Pitting can only occur if the maximum values for the chloride content of water, as defined in the applicable regulations, are significantly exceeded.

External corrosion

External corrosion of SudoPress stainless steel system components can only occur when wet drinking water pipes come into contact with mortar, droplets or coatings that contain or produce chlorides. Check that the outer insulation layer of the pipes and fittings is continuous and that sufficient corrosion-protective insulation fabric exists if necessary. The use of closed-cell insulation has proven to provide effective protection against external corrosion.

Carbon steelInternal corrosion

Internal corrosion cannot occur with closed circuit heating systems. The oxygen in the water in closed systems is used to create iron oxide inside pipes, preventing future corrosion. If the heating system is not in use, it must be kept full at all times, or, alternatively, be completely drained and subsequently dried out, to avoid the presence of water and oxygen in the system at the same time.

The appropriate additives must be added to prevent damage due to freezing, calcification or corrosion. Contact COMAP for further details on the use of additives. To prevent external corrosion, please comply with local directives, regulations and law.

External corrosion

In general, carbon steel systems are installed in such a way that external surfaces do not come into contact with corrosive substances. However, SudoPress carbon steel pipes must not be permanently exposed to moisture. SudoPress carbon steel pipes with polypropylene coating provide effective protection against corrosion.

4.1. Internal corrosionHeating systemsOxygen cannot enter closed circuit heating systems if high quality fittings and equipment are used. When filling the pipes, a small quantity of oxygen contained in the water is directly absorbed by the internal pipe surface and a thin layer of iron oxide forms on this surface. No corrosion can occur after this point. The decrease in thickness in the pipe wall is negligible. The heating-circuit water is practically oxygen-free after this reaction.

CopperCopper pipes and fittings are suitable for all open and closed heating systems. Mixed systems: Copper can be used with other metals in any pipe section in mixed installations.

Stainless steelStainless steel pipes and fittings are suitable for all open and closed heating systems. Mixed systems: Stainless steel can be used in mixed installations along with other materials in any section of the pipe system.

Carbon steelInternal corrosion is normally impossible in closed circuit heating systems with carbon steel pipes and fittings as oxygen from outside cannot enter the system. Mixed systems: Unalloyed carbon steel can be used without problems and can be combined with other metals in any section of a closed system.

Other possible combinationsCarbon steel – copper – stainless steel. Mixed systems: These metal combinations are possible in all closed systems without limitation.

AdditivesAs a preventive measure against the unacceptable absorption of oxygen, oxygen inhibitors can be added to heating-circuit water. Comply with the instructions of the supplier.

(Drinking) water systemsCopperThe physical and chemical properties of drinking water can be affected by copper in the event of internal corrosion. Depending on its composition, even drinking water can cause corrosion.

Copper may therefore be used for systems if the salt content of the drinking water fails to exceed the threshold defined by authorities and regulations. If limit values are not exceeded and the properties of the drinking water fail to cause damage to the copper, this metal may be used for sanitary systems.

Stainless steelSudoPress pipes and fittings in stainless steel have the advantage of being non-reactive to potable water. The physical and chemical properties of drinking water are not affected by stainless steel. In this passive situation, no internal corrosion will take place. Using stainless pipes and fittings will avoid the risk of heavy metal contamination and the growth of bacteria.

SudoPress stainless steel system components are suitable for all processing methods (water hardening) used by drinking water systems and are also corrosion resistant for water containing glycol, demineralised water and distilled water.

SudoPress stainless steel fittings and pipes are however not suitable for use in dosing systems, for example for the disinfectants added to drinking water. SudoPress stainless steel fittings and pipes are also suitable for all other open and closed water supply systems (e.g. cooling water).


175

Mixed systemsThe corrosion behaviour of stainless steel is not influenced by its use in mixed installations, independent of the direction of the flow of water (no flow rule). Stainless steel components can be used in any pipe section in mixed systems. Discolouration caused by a deposit of corrosive foreign matter does not indicate corrosion of stainless steel. Stainless steel can be used with all copper alloys (bronze, copper or brass) in a mixed system. Stainless steel is not at risk from contact corrosion.

Carbon steelCarbon steel pipes and fittings are not authorised in drinking water systems. In carbon steel, contact corrosion will occur if the metal is brought into direct contact with stainless steel.

If bronze, copper or brass fittings are used in between carbon steel and stainless steel components, the possibility of contact corrosion is negligible. Contact corrosion on a carbon steel pipe can also be prevented by using 50 mm bronze, copper or brass fittings.

Fluid flow in a mixed system

Metal the least noble Carbon steel

Copper

The noblest metal Stainless steelFlow direction

For mixed systems (more than one type of metal used in one single system), it is important for the noblest metal to be downstream (in terms of fluid flow) from the system.

4.2. External corrosionGeneralThe conditions required to cause external corrosion do not usually occur in buildings. It is however possible for systems to be subjected to the undesired penetration of rain or humidity for quite long periods, which can cause problems. Operators and assemblers are responsible for taking corrective action. Only suitable corrosion protection can offer permanent corrosion prevention. For this purpose, closed cell insulation can be used, and must be placed in a location with guaranteed sealing. Basic or metallic paints offer minimum corrosion protection. The systematic use of corrosion protection on pipes in conditions where corrosion is likely to occur (damp room, crawl spaces, etc.) is recommended.

CopperCopper is highly resistant to corrosion. Corrosion protection is therefore not required with copper. However, in some cases, it is necessary to protect copper from corrosion due to the presence of sulphates, nitrates or ammonia, which could cause corrosion.

Gas pipes must be protected against corrosion.

Stainless steelExternal corrosion can only occur in the following conditions:

- If stainless steel heat-conducting pipes (50°C) come into contact with building and insulating materials containing chloride (under the effects of humidity)

- If water vapour on heat-conducting stainless steel pipes leads to localised concentration of chloride.

- If stainless steel pipes (or cold water pipes) come into contact with gaseous chlorine, salt water or (oxygen-saturated) water with high chlorine content.

If there is any risk of extended contact between building materials and highly chlorinated water, effective corrosion protection must be used. Stainless steel pipes embedded in cement floors will not be subject to electrolytic external corrosion caused by equipotentiality.

sion

176

Carbon steelSpecial consideration should be given to external corrosion prevention when in a humid environment for an extended period. Only if carbon steel is subjected to occasional corrosive conditions due to humidity will the carbon steel also be resistant against corrosion for a longer period. Carbon steel press fittings must be protected if an increased risk of corrosion exists due to external electrolytic corrosion (or longer periods of humidity). A synthetic polypropylene duct will provide effective corrosion protection for carbon steel pipes.

4.3. Importance of use and treatmentsGeneralCorrosion can occur due to poor system design or incorrect use.

The following points must be compled with:

Grinding stainless steel

Grinding stainless steel pipes is not authorised due to the high temperatures reached in this operation.

Bending stainless steel pipesStainless steel pipes may not be hot bent. Heating stainless steel pipes will alter the structure of the material (sensitization) and could lead to inter-crystalline corrosion.

Heat transfer (e.g. with heating tape)Heat transfer from outside the pipe to inside the pipe must be prevented as this can lead to the build-up of a film on the inside of the pipe wall. This film can lead to an increase in the concentration of chloride ions, which can cause discharge corrosion at critical concentrations.

WeldingPitting may occur when welding stainless steel fluid pipes. In the case of TIG welding for stainless steel, discolouration occurs at the welding seams, which can lead to corrosion upon contact with salt water. This discolouration, mainly inside the pipe, can only be removed by etching, which is not feasible when the pipes have already been installed.

Copper - stainless steel – carbon steelIrrespective of the material used (copper, stainless steel, carbon steel), water pipes can corrode subsequent to the interaction of three elements (water – metal – gas (air)). This corrosion can be prevented if the pipe is filled at all times after initial filling. If the pipes must be emptied once again after water compression testing, this is considered as partial filling. In this case, gas/air compression testing is recommended.

4.4. The effects of insulationGeneralInsulation normally offers no protection against corrosion except for “closed cell insulation” (airtight and watertight), which offers effective corrosion protection.

Insulating stainless steelInsulating material that releases chloride ions in the water or could cause the local proliferation of chloride ions is not permitted. The thermal insulation of pipes may include a mass proportion of up to 0.05% of water-soluble chloride ions.

Insulating carbon steelIf no humidity is present between the insulating material and the pipe, no corrosion can occur. If humidity is present under the insulating material (due to condensation), the external surface of the pipe will corrode.

6. 10 YEAR WARRANTY ON COMAP SYSTEMS

USAGE CONDITIONS

For its piping systems (copper, PEX, multilayer and carbon/stainless steel) and associated fittings (SkinPress, SudoPress, XPress and Tectite), COMAP offers a manufacturer’s guarantee of 10 years for all incidents in which it is responsible.

This warranty applies with the following conditions:

1 All products necessary to the installation (manifolds, pipes, polystyrene tiles, fittings, pressing tools, connection accessories and additional components in the product line) that is covered by this guarantee are from COMAP product lines, for applications as specified in the Technical Notices published by the CSTB or, if these do not exist, in COMAP sales literature.

2 The implementation has been performed following current trade practices (EN, NF, DTU or CPT), or following the procedures described in COMAP technical manuals and sales literature. Failure due to external causes (puncture, freezing, crushing by mechanical means, etc.) is not covered.

In addition, installation must have been performed by a professional. (Business registration number and invoice must be provided.)

3 The guarantee is effective beginning on the date that the installation of the concerned products is complete, as indicated on the attached certificate of guarantee, for a period of 10 years.

4 The certificate must be fully completed and returned to COMAP at the above-mentioned address, no more than 2 months following the date declared in § 3. The request is recorded and archived by COMAP, and a copy countersigned by COMAP is returned to you, as proof. You must provide this copy to submit a claim under this guarantee.

5 In cases in which COMAP approves, in its sales literature, a use not yet established in the texts that govern current trade practices, following the procedures established by COMAP will cause this guarantee to be applied.

Specifically, embedding of press fittings is authorised by COMAP only for bypass or tapping (no extensions or “joins” within a slab or partition wall for non-copper pipes). In these cases, users should surround the fitting with padded or adhesive tape, in order to protect it from direct contact with its encasing.

This directly concerns tees, MultiSkin and PEX crimped pipes for heating, as well as straight sleeves for repairing underfloor heating pipes. Fittings that have threaded or tapped pieces must not be embedded.

6 In the specific case of press-fittings, the 10-year guarantee applies only when COMAP fittings are utilised with pipes (except copper) and machines marketed by COMAP.

You will be asked to show the necessary documents that demonstrate that the pressing tool has received necessary maintenance as specified in its technical manuals.

* In the specific case of copper press fittings, the guarantee is applicable exclusively with copper pipes that conform to the EN 1057 standard, or to specifications mentioned in COMAP documentation.

7 In case of questions, only the Sanitary and Heating Systems Department technical assistance team of COMAP France, or personnel trained by this department, are able to provide information on operating procedures.

8 All incidents must be reported within 5 days from when you become aware of the problem. This declaration may be made only by registered letter with acknowledgement of receipt, or by fax, addressed to COMAP France 16 avenue Paul Santy - BP8211 - F 69355 Lyon Cedex 08.

As soon as the incident has been discovered. Protective measures must be implemented to minimise consequences.

9 Failure to comply with any provisions in the preceding paragraphs will mean that COMAP is automatically absolved from all obligation under this guarantee.

10 The guarantee does not cover indirect consequences of any incidents, such as operating losses, damages and interest, loss of asset use, loss of building or other property value, or other consequences not mentioned here.

11 The guarantee covers the replacement of the components judged to be defective that have caused the incident, as well as reasonable expenses for restoring damaged premises to their initial state previous to the incident, as estimated by experts.

12 Where appropriate, COMAP reserves the right to engage a company of its choice to perform the repairs to the system that is the subject of the claim.

13 For damage claims, COMAP possesses professional liability insurance, the certificate for which may be supplied upon demand.

14 Any agreement other than in writing, on terms not stipulated in these conditions, will be considered invalid.

15 This guarantee is for the project described on the certificate. It is therefore transferable if the building is sold. This guarantee applies for the specified site, until the specified date, and is valid even if COMAP ceases trading before that date.

16 For all other matters not mentioned in the preceding paragraphs, refer to the general conditions of sale appearing on the COMAP price list that is current on the date that the incident is reported.

17 Under the conditions detailed above, COMAP’s responsibility will be limited to €770,000.00 per incident and per year.

18 Each claim under the current guarantee may be made only through insurance companies, using their established procedures.

Specifically, for all incidents, the installer must make the report first to its own insurance company, and alert COMAP as specified above.

Repairs may be performed only following inspection and authorisation by the expert designated by COMAP’s insurance company; otherwise, repairs may not be compensated, and may cause the cancellation of this guarantee.
