Description of basic system

The basic range o Uponor products

includes all system components de-

signed or dierent uses in a varietyo applications, e.g. tapwater and

radiator connection as well as radi-

ant heating/cooling.

Description pipe

The Uponor multi-layer composite

pipe (MLCP) is a pipe generation

that unites the advantages o a

plastic and metal pipe and thereore

oers a high degree o fexibility

and toughness, coupled with highpressure and temperature resistance.

The Uponor MLC pipe consists o a

longitudinal saety welded alumini-

um pipe, to which an inner and out-

er layer o high temperature resist-

ant polyethylene is applied (in

accordance with DIN 16833). Owing

to the specic orm o the octene

side chains in the molecular struc-

ture o the material, a similar eect

is achieved when polyethylene is

cross-linked.

All layers are permanently bounded

together by means o an intermedi-

ate adhesive layer. A special welding

technique guarantees a maximum o

saety. The thickness o the alumini-

um selected or the Uponor MLC

pipe is exactly adapted to the com-

pressive strength requirements as

well as the bending capability.

Smaller dimensions o MLC pipes are

designed so that the aluminium layer

neutralises the snap-back orces o

the plastic material, enabling easier

pipe installation with minimal eort.

Larger dimensions o MLC pipes and

straight lengths o pipes have a

greater aluminium layer thickness,

making them stier and suitable or

use as risers. The aluminium pipe is

important or heat expansion. Ow-

ing to the permanent bond between

plastic and aluminium, thermal ex-

pansion is determined by the expan-

sion actor o the aluminium and

roughly corresponds to that o a

metal pipe, i.e. only 1/7th o theexpansion o a pure plastic pipe.

This oers advantages or pipe in-

stallation, since the use o compen-

sating points is largely unnecessary.

The smoothness o the inner plastic

layer oers water no points o at-

tack. Incrustration and corrosion are

prevented in normal use. The trans-

mission o fow noise or noise, e.g.

emitted by circulating pumps, is re-

duced to a minimum due to the spe-

cic properties o the raw material.

The most important advantages o-

ered by MLC pipes are:

Absolutely diusion-tight,

exceed the requirements o

DIN 4726

Hygienicly harmless

Minimal roughness k = 0.0004 mm

ensuring less pipe riction and

lower pressure losses

Form stable, by compensation

and reduction o snap-back orces

Highly fexible, making smaller

dimensions (up to 32 x 3 mm)

simple to bend by hand or with

the corresponding toolHeat expansion similar to that o

metals, enabling larger pipe clip

distances

Clean and easy to install, no

welding, soldering, thread cut-

ting or bonding

Corrosion-resistant, thanks to its

inner and outer plastic layer

Excellent long-time rupture

strength oers saety in daily use

Maximum temperature: 95 C *

Maximum continuous operatingpressure: 10 bar at 70 C continu-

ous operating temperature, with a

tested longtime rupture strength

Low weight, easy handling

Coils and straight lengths in

numerous sizes

The DGVW approval permits the use

o Uponor MLC pipe or drinking

water supply systems according to

DIN 1988 TRWI. The approval in-

cludes a positive assessment o the

material according to the law gov-

erning plastic articles or ood use in

drinking water supply, called KTW

recommendation or short.

Press ttings

The patented MLCP pressing system

enables connections to be estab-

lished within a matter o seconds

without welding or soldering. The

externally xed press sleeve, which

is permanently connected to the

tting, oers protection against

mechanical infuences on the

o-rings. The press sleeve has

inspection windows to check the

insertion depth o the pipe in the

tting beore pressing. The plastic

stop ring on the shaped aluminium

press sleeve simplies the task o

attaching the pressing jaws. The

stop rings are colour coded to

ensure an optical press marking.

Ater the pressing procedure the

rings all o. The pressing jaws and

the stop rings o the same dimen-

sion have been marked with the

same colour code. Ater installation,

the connection is capable o

ab-sorbing bending orces, due to

the orm stable press sleeve,

without any leakage occurring.

Ater pressing the pipe can be

readjusted.

Compression ttings

The MLC range o compression t-

tings is designed to enable all con-

ventional applications.

MLC compression ttings press the

insert part (2) with xed closed

clamp ring (3) on to the MLC pipe

by tightening the swivel nut (1).

The compression tting can be

released again; whereas the insert

part, made o PPSU, remains per-

manently connected to the pipe.

All inch compression adapters in-

clude eurocone threaded parts.

Both press and compression ttings

are permanently tight as conrmed

by SKZ test reports and DVGW

certicates.

Quality control

Constant quality controls beore

and during production:

Online inspections using special

cameras, ball test, spiral test,

measurement and tensile test.

In the works laboratory: Raw

material testing, pipe tests using

test piece (peeling test, thick-

ness gauging), pressure and

temperature tests and hot stor-

age test.

Tests carried out by neutral Ger-

man and international test insti-

tutes.

According to the DVGW worksheet

W 542, the minimum long-time

rupture strength o multi-layer

composite pipes in drinking water

distribution systems must be veri-ed over a period o minimum 50

years. For this purpose, an inde-

pendent test institute perorms a

number o tests and prepares the

resulting internal pressure resistance

diagrams.

These values are provided by the

SKZ or Uponor MLCP. In addition

to urther tests, the values shown in

the long-time internal pressure dia-

grams orm the basis or the issu-

ance o the DVGW system test mark

or MLCP with associated connec-

tors. Together with the test institute

and DVGW, Uponor is constantly

working on pipe system tests in

conormance with the associated

worksheets o the DVGW.

The aim o these endeavours is to

assure the quality o all currently

approved MLCP products as well as

extending the DVGW approval to

new parts, ttings and pipe dimen-sions in the MLCP range o products.

The thermal expansion resulting

rom the mode o operation must be

taken into account in the design o

the pipe layout. The temperature

dierence t and pipe length L play

a decisive role in thermal expansion.

For all installation variants, the ther-

mal expansion o MLC pipes must

be taken into account. For pipes in-

tended or concealed installation or

installation in screed, the thermal

expansion is absorbed by insulation

in the area o directional change.

The thermal expansion is calculatedaccording to the ollowing ormula:

l = x L x t

Where the ollowing are:

l: Thermal expansion (mm)

: Thermal expansion coecient

(0.025 mm/(m x K))

L: Pipe length (m)

t: Temperature dierence (K)

For the planning and installation o

distributing and rising mains with

MLC pipes, in addition to the struc-

tural requirements, also thermal ex-

pansion aspects must be taken into

account.

Rigid installation with MLC pipe is

not possible. Thermal expansion othe pipes must always be absorbed

or controlled.

Exposed MLC pipes ully exposed to

thermal expansion, must be provid-

ed with appropriate expansion com-

pensation. For this purpose, a

knowledge o the position o all

xed points is necessary. Compensa-

tion always takes place between two

xed points (FP) and directional

changes (bending leg BS).

Construction project:

Stage:

Person carrying out the test:

Test pressure = max. permissible operating pressure + 5 bar 15 bar

(related to the lowest point of the system)

All tanks, equipment and fittings, e.g. safety valve and expansion tanks, which are not suitable for the pressure test, must be removed

from the system during the test period. The system is filled with filtered water and completely vented. A visual inspection of the pipe

joints must be made during the test. After the test pressure has been reached a suitable time must elapse to allow for temperature

equalisation between the ambient temperature and the temperature of the fill water.

If necessary, the test pressure must be re-established after the waiting period.

Preliminary test

Begin: Test pressure:oclock,

Date Time

Re-establish the test pressure two times within 30 minutes at intervals of 10 minutes then wait 30 minutes and read the test pressure

After the test pressure has been reached, a suitable time must elapse to allow for temperature equalisation between the ambient

temperature and the temperature of the fill water. If necessary, the test pressure must be re-established after the waiting period.

All tanks, equipment and fittings, e.g. safety valve and expansion tanks, which are not suitable for the pressure test, must be removed

from the system during the test period. The system is filled with filtered water and completely vented. During the test a visual inspection

of the pipe connections must be made.
