Designed For Secure MountingCast iron anodes provide excellent protection in aqueous environments. For structures such as water boxes, locks and dams, where space is limited and fl uctuating water velocities are present, Corrpro supplies button and bullet cast iron / silicon anodes. The anodes are designed for secure mounting on the sides of metal structures and are made using the Durichlor 51 alloy. This alloy allows for a low anode consumption rate of between 0.75 and 1.0 lb/amp-yr and an operating current density of 1 amp/ft2. The anode’s superior operating performance is made possible by the presence of chromium and silicon in the Durichlor alloy. Chromium gives the anodes extra durability, thus making them less susceptible to damage from abrasion or erosion. Silicon in conjunction with chromium causes silicon dioxide to form on the surface of these anodes. With this fi lm, the anodes are more resisant to low pH environments, are better protected from pitting, and are more conductive in aqueous electrolytes.

Corrpro button and bullet anodes are offered in several different mounting confi gurations. The button anodes are designed for fastening by either bolts, pre-cast studs in the anode, or welded studs on the protected structure. Lead wire connections can be made either parallel or perpendicular to the mounting fastener. Bullet anodes are attached by a 10” long metal rod, which is coated with a special epoxy resin and covered with non-conductive tubing. The metal rod serves as the lead wire connection for the bullet anode.

Typical ApplicationsButton and bullet anodes are designed specifi cally for use in water environments where a small and secure anode is preferred. Button anodes are most often used on locks, dams and other structures where a low profi le anode is required. The bullet anode which is mounted on a metal rod is ideally suited for use in condenser water boxes. Both anode types operate effi ciently in fresh, brackish and salt water environments.

Proven Long Life ProtectionHigh silicon cast iron anodes have been used for more than fi ve decades to protect buried and submerged structures from corrosion. Over this time period, they have proven to be one of the most reliable protection materials available. To meet the large demand for this product, Corrpro manufactures a wide assortment of solid cast iron anodes for use on all types of structures. The anodes are cast using the Durichlor 51 alloy. This special alloy composition gives Corrpro anodes added strength. It also allows the anodes to form a thin fi lm of silicon dioxide on their surface which reduces the rate of consumption. Consumption ratings for solid Corrpro cast iron anodes are from 0.75 to 1.0 lbs/amp-yr in sea water. The anode’s recommended operating current density is at or below 1 amp/ft2.

To compensate for end effect which causes increased consumption at the longitudinal ends of an anode, Corrpro solid cast iron anodes are back beveled with more material near the connection. A choice between epoxy encapsulated, epoxy cap, or heat-shrink cap connection sealant is also offeredRegardless of which sealant is chosen, the wire-to-anode connection resistance will be less than or equal to 0.004 ohms.

H I G H S I L I C O N C A S T I R O N A N O D E SCorrpro® Durichlor 51™ Solid Silicon Cast Iron Anodes

Typical ApplicationsSolid cast iron anodes can be used in both soil and water electrolytes. Their unique chemical compositon makes them effective in saline mud, brackish water and other environments containing chloride ions. The anodes also perform well in deep and conventional groundbed applications where halogen gases are often generated. While the anodes may be installed either bare or in a backfi ll, improved operating effi ciency can be obtained with the use of a backfi ll in non-aqueous soil applications. The backfi ll increases the anode’s discharge area and lowers its consumption rate. Corrpro cast iron anodes are available bare and prepackaged in a Spira-Pak® canister containing a coke breeze backfi ll.

Ordering ProcedureCorrpro solid cast iron anodes are available in numerous confi gurations and with several wire-sealing options. To order the required anode for your structure, indicate that you need a solid cast iron anode. Specify the quantity desired, the anode type, encapsulation, wire length, size, insultation, and whether the anode should be packaged or bare.

Powerful Protection and Uniform ConsumptionAll conventional impressed current anodes are consumed over time. With Corrpro tubular cast iron anodes, however, effective protection is provided at a low and very uniform consumption rate. The anodes are made using the Durichlor 51 alloy, which is consumed at a rate of 0.75 to 1.0 lbs/amp-yr in seawater.

In addition to chemical composition and casting techniques, the confi guration of Corrpro tubular anodes also contributes to improved operating performance. Their unique tubular design provides greater surface area over solid cast iron anodes of identical weight. This in turn lowers anode-to-earth resistance, decreases the current density on the surface of the anode, and permits any generated gases to be distributed over a larger area. The tubular design also means the wire connection can be made in the center of the anode, thus eliminating the problem of end effect consumption. In all Corrpro tubular cast iron anodes, the proven Wedgelok® connection is used. It consists of two angled metal contacts that wedge together, forming a strong bond to the anode, and assuring a low-resistance connection under 0.001 ohm.

ApplicationsTubular cast iron anodes operate effectively in a variety of electrolytes, from soil and freshwater to brackish and saltwater environments. Under normal conditions, a thin fi lm of silicon dioxide will develop on the surface of these anodes. This fi lm protects the anodes from pitting, lowers the consumption rate, and makes them ideally suited for deep-groundbed applications. Corrpro tubular cast iron anodes can be installed bare or in a coke breeze backfi ll. Use of a backfi ll does, however, effectively increase the anodes’ discharge area, and lowers its consumption rate.

G R A P H I T E A N O D E SCorrpro® Graphite Anodes

Protection for Arid EnvironmentsChoosing the right impressed current anode for a particular protection project is highly dependent on the environment which surrounds a buried or submerged structure. In relatively dry soils, graphite anodes have proven to be an ideal choice. Corrpro manufactures a complete line of graphite anodes which are produced according to strict quality control guidelines. The anodes are composed of high quality petroleum coke which is mixed with coal tar binders and extruded into various diameter rods. The rods are heated repeatedly at temperatures in excess of 2,600°C and then cooled. The end result of this manufacturing process is an anode with a high percentage of carbon which can deliver effective protection at a relatively low consumption rate. In buried soil electrolytes, with coke backfi ll, this consumption rate varies between 0.4 and 2.0 lbs/amp-yr. Due to the fact that graphite anodes are inherently very porous, Corrpro treats its graphite anodes with a microcrystalline wax. This wax inhibits moisture naturally penetrating the anode and extending the life.

A quality connection is an integral part of any high performance graphite anode. In addition to offering a standard end connection, Corrpro also produces a low-resistance center connection. Center wire connections were developed to compensate for end effect. In this phenomenon, increased consumption occurs at the longitudinal ends of an anode. Corrpro’s center connection compensates for this effect. The lead wire connections in graphite rod anodes are made with an alloyed lead ferrule soldered to a tinned stranded copper conductor. The lead wire ferrule assembly is inserted into a predrilled hole in the end of the anode and hydraulically compressed to expand in an outward direction against the wall of the drilled hole. The connection made will withstand a minimum pull-out strength of 300 lbs. with a wire connection resistance under 0.004 ohm.

ApplicationsWhile graphite anodes will operate in aqueous environments, they perform best under dry soil conditions. Use of a backfi ll effectively increases the graphite anode’s discharge surface area and lowers anode-to-earth resistance. The anodes have been successfully used in both conventional and deep ground bed applications, and demonstrate exceptional protection in high chloride environments.

M I X E D M E T A L O X I D E A N O D E SCorrpro® Mixed Metal Oxide Probe Anodes

Rugged and Easy to InstallMixed metal oxide anodes have very low consumption rates under 1.0 mg/amp-yr, and can be operated at high current densities approximately 10 amps/ft2 in freshwater and over 50 amps/ft2 in salt water. Because of these impressive performance capabilities, Corrpro manufactures mixed metal oxide probe anodes for use in heater treaters, condenser water boxes, and pressure vessels. The anodes are composed of titanium rods, which are covered with a mixed metal oxide coating. The titanium is inherently resilient and stable, allowing the probe anodes to withstand water turbulence without damage. Because the titanium does not discharge current, electrical current transfer is accomplished through the mixed metal oxide coating. The coating is immune to abrupt current reversals, and may be exposed to high current overloads for initial structure polarization without causing harm to the anode.

Unlike sacrifi cial anodes, which must be installed within tanks or other vessels, Corrpro probe anodes are designed for mounting and replacement through the wall of the vessel. The anodes are attached to a threaded stainless steel pipe, which is fi lled with a watertight sealant. To provide a high pressure connection, the anodes are bonded with G-10 fi berglass, and pressure tested prior to shipping. The fi berglass restricts water fl ow and lends extra support to the anode. Lead wire connections are made in a cast metal junction box. The junction box attaches to the stainless steel threaded pipe once the anode is securely in place. The anodes are also adaptable for mounting while the pressure vessel is in service.

M I X E D M E T A L O X I D E A N O D E SCorrpro® Mixed Metal Oxide Ribbon Anodes

Protection For Above Ground Tank BottomsCathodic protection is an economical method for controlling corrosion on aboveground storage tank bottoms. While sacrifi cial systems can be used, impressed current designs have proven to be more cost effective and easier to install. To address this particular application, Corrpro manufactures impressed current tank bottom anodes that employ a patented grid-shape geometry. The anodes are composed of a titanium ribbon substrate coated with a mixed metal oxide catalyst. Because the titanium substrate is naturally passivated by an oxidizing fi lm, the ribbon anode remains dimensionally stable over time. Direct current transfer is accomplished through the mixed metal oxide catalyst which is highly conductive, and fully oxidized so that higher current outputs are possible. This two part composition allows for a maximum current density of 5.0 mA/ft to achieve a 50 - 100 year design life.

In addition, to compositional advantages, the unique confi guration of Corrpro’s anodes offers numerous other benefi ts. Spacing between the metal anode strips can be adjusted to achieve various design life requirements. The anodes can also be easily cut so that placement may be made under all areas of the tank. Because the strips are electrically continuous, multiple paths are available for current fl ow. This in turn lowers the driving voltage required for protection, and provides the anode with redundant electrical connections for increased reliability. Greater dependability is also achieved through the elimination of fi eld splices.



Mixed Metal Oxide

ApplicationsCorrpro’s mixed metal oxide ribbon anodes are designed for use on both newly constructed aboveground storage tanks with secondary containment liners, and existing tanks utilizing double-bottom construction. Unlike other impressed current tank bottom anodes, Corrpro’s ribbon anodes do not require coke breeze. They can be used in sand with various levels of moisture and salt content, and can be designed to provide effective protection for 50 years or more.

Ordering ProcedureCorrpro’s mixed metal oxide anodes deliver long term protection to aboveground storage tank bottoms. To order the required anode material for your structure, indicate that you need a mixed metal oxide ribbon anode. Specify the number of linear feet desired. The anode ribbon is available standard in 500 foot reels. The conductor bar is stocked in 250 foot reels. An example is provided to help illustrate this process.

M I X E D M E T A L O X I D E A N O D E SCorrpro® Mixed Metal Oxide Solid Rod Anodes

Lightweight and Easy to InstallThe use of large and heavy impressed current anodes has traditionally been thought to be the only method for protecting numerous types of buried and submerged structures. However, with the development of the mixed metal oxide anode, this notion has been greatly challenged. The anodes are small, lightweight, and can operate at current densities much higher than conventional impressed current anodes approximately 10 amps/ft2 in soil and fresh water, and over 50 amps/ft2 in sea water. In addition, the mixed metal oxide coating on the anodes has an almost negligible consumption rate of less than 1.0 mg/amp-yr. Corrpro manufactures a full line of solid mixed metal oxide anodes for use in a variety of environments. The anodes are composed of titanium rod substrates which are coated with a mixed metal oxide catalyst. The titanium rod is inherently stable, thus the transfer of direct electrical current is performed through the mixed metal oxide coating. The end result is a high-performance anode with an extremely long life.

As with any impressed current anode, a reliable lead wire connection is critical to the operating performance of mixed metal oxide anodes. On Corrpro solid rod anodes, a crimped wire connection is made using twelve tons of hydraulic compression. The crimped connection is then covered with two types of moisture resistant mastic tape and sealed with a heat shrink sleeve. This extremely reliable connection has proven to prevent electrical breakdowns and produce a low resistance of under 0.004 ohms.



Mixed Metal Oxide

ApplicationsCorrpro rod anodes perform well in all types of environments. Their mixed metal oxide coating prevents substrate attack in even highly acidic environments. The anodes have been used with great success in deep and conventional groundbeds, and in fresh, brackish and salt water electrolytes. Corrpro supplies the anodes either bare or packaged in canisters containing petroleum coke breeze. For aqueous environments, the anodes can also be provided in a specially designed PVC perforated tube that directs current fl ow and provides extra protection to the anode.

Ordering ProcedureSolid rod anodes are available from Corrpro in a number of diameters and lengths. Lead wires can be attached to one end of the anode for conventional use, or to both ends to form anode strings. To order the required anode for your structure, indicate that you need a solid rod mixed metal oxide anode. Specify the quantity desired, the anode type, the lead wire length, size, insulation, whether it should be packaged, bare or placed in a PVC tube. An example is provided to illustrate this process.

M I X E D M E T A L O X I D E A N O D E SCorrpro® Mixed Metal Oxide Tubular Anodes

Dimensionally Stable in All EnvironmentsTo obtain the highest level of protection from an impressed current cathodic protection system, you need an anode with a very low consumption rate and high current capacity. With Corrpro’s tubular mixed metal oxide line of anodes, you get powerful protection and unsurpassed stability. The anodes are made using tubular titanium substrates which are coated with a mixed metal oxide catalyst. The catalyst is thermally applied to the titanium to form an extremely chemical resistant bond. This special composition brings together the stability of titanium with the conductive properties of the mixed metal oxide catalyst to achieve superior performance. In soil and fresh water applications, the anodes have a recommended current density of approximately 10 amp/ft2, and can be operated over 50 amp/ft2 in sea water environments. Even at these relatively high discharge levels, the anodes will be consumed at less that 1.0 mg/amp-yr.

The tubular design of these anodes also allows for numerous performance benefi ts. The tubular confi guration provides a larger surface area which in turn permits greater current output and lower anode-to-earth resistance. The tubular style also means lead wire connections can be made in the center of the anode. WIth Corrpro tubular anodes, this connection consists of a brass wedge connector which grips fi rmly to the internal circumference of the anode. This connection is protected from moisture intrusion by a waterproofi ng sealant which fi lls the entire anode tube. One end of the anode is then covered with shrink tubing for a completely sealed electrical connection. Anodes are then tested for quality assurance.

ApplicationsMixed metal oxide anodes have proven to operate effectively in all types of environments including areas with extremely low pH levels under 1, and high chloride concentrations. While Corrpro tubular anodes can be used singularly, their unique confi guration also makes them ideal for use in strings on offshore platforms or in deep groundbeds. In addition, the string anodes can be installed parallel to transmission pipelines, or used for other special applications.

Ordering ProcedureCorrpro tubular mixed metal oxide anodes are available in several different dimensions. To order the required anode for your structure, indicate that you need a tubular mixed metal oxide anode. Specify the quantity desired, the anode type, the lead wire length, size, insulation, and whether it should be packaged or bare. An example is provided to illustrate this process.

Lightweight and Dimensionally StableThe many benefi ts obtained by using mixed metal oxide anodes are well known. These include low consumption rates, dimensional stability and high current densities. Wire mixed metal oxide anodes possess all these characteristics and also offer greater installation fl exibility. The anodes are composed of a copper core, which is surrounded by a titanium substrate. Metallurgically bonded to the substrate is a mixed metal oxide coating. The combination of these three materials produces an anode capable of superior operating performance. The titanium is inherently resilient and stable, allowing the wire anode to be extremely fl exible. Because this metal does not discharge current, electrical current transfer is accomplished through the mixed metal oxide coating. The coating is immune to abrupt current reversals, and may receive high current overloads for initial polarization without causing harm to the anode.

Corrpro wire anodes can be used in numerous geometries. In water storage tanks, the anode is often suspended by rope in confi gurations that follow the circumference of the structure. This design permits even current distribution. It also produces a cathodic protection system that is not susceptible to damage from icing. Because the anode is a continuous wire, failures due to poor wire connections are eliminated.

ApplicationsCorrpro mixed metal oxide anodes can be used in both aqueous and soil electrolytes. They deliver superior protection in fresh, brackish or salt waters, and have been found to be resistant to acid attack. The anodes can operate in temperatues of up to 175°C. They should not be used in electrolytes containing barium or cadmium.

Ordering ProcedureThe mixed metal oxide wire anode is available in different current output ratings. To order the right wire anode for your particular application, indicate that you need a mixed metal oxide wire anode. Specify the lineal feet desired and the wire type. An example is provided to illustrate this process.

M I X E D M E T A L O X I D E A N O D E SDe Nora LIDA® Wire Anodes

LIDA wire anodes are copper titanium wire with a mixed metal oxide coating. The mixed metal oxide is a crystalline, electrically conductive coating that activates the titanium and enables it to function asan anode.

LIDA wire anodes are manufactured in two diameters, 1.5 millimeter and 3.0 millimeter.

When applied on titanium the coating has an extremely low consumption rate measured interms of milligrams per year. As a result of this low consumption rate, the wire diameter remainsnearly constant during the life of the anode.

The low consumption rate of the mixed metal oxide coating at the recommended operating currentdensities result in projected anode lifetimes from 15 to 20 years. Longer or shorter lifetimes may beobtained by varying the current output per foot per wire.

Anode Coating — The coating used on wire is suitable for most cathodic protection applications,but output varies with application.

LIDA mixed metal oxide coating demonstrates a very high chemical stability, even in environments with very low pH values.

Unlike other impressed current anodes, the LIDA® coating is not affected by the generation of chlorine.

Lead Wire Connection — A typical connection between the LIDA wire anode and a header cable,have been used successfully in canistered anodes since 1987.

ApplicationsCanistered anodesContinuous horizontal groundbedsDiscontinuous horizontal groundbedsShallow vertical groundbedsDeep anode groundbedsAbove ground storage tanksUnderground storage tanksFresh water

Electrical cable shielding Water storage tanks Water treatment equipment

Resistivity Versus Length — Proper current distribution is an important factor in the design and proper use of an anode wire for each application.

For example, if a wire voltage drop of 10% or less is desired for proper current distribution in 1000ohm-cm water, anode segments of 50 feet should not be exceeded between electrical connections to a header cable with the 1.5 mm diameter wire. By comparison, use of the 3.0 mm diameter wirewill permit the use of 110 foot segments, while still allowing the desired 10% voltage drop.

As with all electrical conductors, the operating temperature of the wire effects the resistance. The table below, shows this effect by assuming the wire will operate at the temperature of the surrounding electrolyte. The change in resistivity also changes the maximum ampacity of the wire.

Savings — In many cases, LIDA mixed metal oxide wire anodes offer savings over competitiveanodes on an installed cost basis. This is possible by balancing the high current density capabilityof mixed metal oxide coatings and the ability to tailor to desired lifetimes.

Flexibility of Use — LIDA wire anodes can be used in a wide variety of cathodic protectionapplications. Their lightweight and malleability allow forming to complex confi gurations. The copper core provides high conductivity resulting in better current distribution along the entire length of the wire.

A LIDA “anode string” is comprised of electrical cable threaded through one or more tubularanodes. Electrical connection between the anode and cable is via a patented, mechanical crimping process. The crimp connection is likewise utilizedto seal the anode around the cable at both ends.

Since only a single cable lead protrudes from the hole, the junction box is eliminated when using a LIDA string — reducing the cost of materials and labor. String assemblies are also available in a looped confi guration with two tails, or as multiple, staggered strings for system redundancy andmaximum current distribution throughout the groundbed.

AdvantagesLIDA Crimp — LIDA anodes are connected with special crimping process which improves the life of the tubular anode system. On the surface, the crimp on the ends and in the middle appears the same. Yet they serve different purposes and are made differently. The center crimp makes electrical contact with the cable while the end crimps form a moisture resistant seal.

Electrical connection between the tubular anode and the power cable wire is achieved by sliding the tube onto the cable and crimping a section of the tube at mid-length around a stripped portion of the cable. Both ends of the tubular anode are sealed over the insulated cable by applying 50 tons of hydraulic pressure. This crimping process eliminates the need for mastic or resin sealants.

Reliability — In choosing the LIDA tubular anode, you have selected the most durable and reliable product in the industry for your cathodic protection needs. LIDA tubular anode strings are backed by a fi ve-year, no hassle warranty. Design, assembly and installation factors have been carefully considered so that your time and costs are minimized as much as possible.

Ease of Installation — The LIDA anode-cable assemblies are easy to handle, transport and install because of their unique fl exibility. It makes your on-site job easier as well.

M I X E D M E T A L O X I D E A N O D E SDe Nora Disk Anode™

The De Nora Disk Anode™ was developed specifi cally for the rigors of cathodically protecting dam and navigation lock gates. Since our disk anodes are designed to operate in fresh, brackish, and seawater environments, other suitable applications include: marine structures, water tanks, and vessels. With an optional primary seal spacer gasket, it can be used on the inside of pipes, tanks, or other curved surfaces.

The active element in the Disk Anode is a 6” diameter x 1/8” thick titanium disk with a mixed metal oxide coating. This mixed metal oxide is a crystalline, electrically conductive coating that activates the titanium and enables it to function as an anode. When applied on titanium, the coating has an extremely low consumption rate, measured in terms of milligrams per year. As a result of this low consumption rate, the dimensions of the anode remain nearly constant throughout the design life.

The mixed metal oxide coated disk is secured into a 12” diameter x 1/2” thick dielectric shield made of a durable, chlorine resistant, molded FRP-vinyl ester. This FRP shield has been designed to resist damage from fl oating debris and ice, as well as serving to enhance the current disributing capability of the disk. The shield also minimizes excessive current damage to the coating on surrounding steel. The low profi le Disk anode fi ts fl ush with the surface, so total protrusion from the steel bulkhead is a mere 1/2”.

The coated titanium disk and shield assembly is attached to a 1-1/4” diameter FRP stud via aninterlocking epoxy joint. This unique joint enhances torque capability and subsequent sealing. A 100% compressible EPDM elastomeric o-ring molded into the shield assures a watertight seal between the disk and steel bulkhead, while simultaneously allowing the shield to fi t fl ush against the bulkhead. Rod threads are platinum plated to prevent oxidation of the titanium — providing a low and constant contact resistance over the life of the anode.

Drill a 15/16” hole through the steel bulkhead. If 1. a 1” hole is already in place, it will be necessary to ream the hole an additional 5/16”. Remove all burrs.Apply silicone caulking to the entire back of the 2. FRP shield being careful not to cover the EPDM seal. This serves to displace water on the steel surface, thereby minimizing corrosion of the bulkhead behind the shield. Enough caulking should be applied so that a small bead forms around the entire shield perimeter after the disk jam nuts are tightened.Once the disk is mounted, install and tighten the 3. lock nuts against each other. It is suggested that the disk be attached at about 50% of its design torque - approximately 25 ft. lbs. On concave surfaces make sure the spacer gasket has been fi tted before installing the disk in the hole.Electrical connection to the titanium rod should be 4. made with a zinc plated spade type wire terminal with a circular opening for a 1/4” rod. Make sure any exposed copper wire is appropriately protected with heat shrink, petrolatum tape, or other suitable water barrier. For submersion service, it is advisable to fi ll 5. the conduit box with a silicone or epoxy potting compound.

M I X E D M E T A L O X I D E A N O D E SDe Nora LIDA® Pack Canistered Wire Anodes

Canistered wire anodes are the perfect impressed current anode for shallow vertical andhorizontal surface groundbeds, as well as wet, marshy soil conditions where caving is likely to occur.

Anode Construction — The primary anode element in a LIDA Pack is a mixed metal oxide wire anode.The wire anode is comprised of a precious metal oxide coating applied to a copper cored titanium wire. The oxide coating is completely stable and does not corrode, as is the case with traditional massive type anodes, such as silicon iron, graphite, or even platinum.

The stable anode element passes current to a highly conductive calcined petroleum coke backfi ll.The backfi ll is well compacted inside a galvanized steel canister. To allow moisture to quickly migrate to the coke backfi ll for increased electrical conductivity, the wire anode element is electrically connected to the steel canister — thereby accelerating the canister corrosion rate once the anode has been installed and energized.

M I X E D M E T A L O X I D E A N O D E SDe Nora LIDA® One Anodes

The “Single Anode” Concept from De Nora — one anode, one cable — It’s that simple.

The LIDA One anodes are the newest in the family of mixed metal oxide anode products specifi cally tailored to the cathodic protection of buried structures. Designed for installations where a single anode on a string is preferred for groundbeds with widely varying soil resistivities, the mixed metal oxide coating is specially formulated for use in carbonaceous backfi ll.

LIDA One is a 1” diameter titanium tube with a precious mixed metal oxide coating. This mixed metal oxide is a crystalline, electrically conductive coating that activates the titanium and enables it to function as an anode. When applied on titanium, the coating has an extremely low consumption rate, measured in terms of milligrams per year. As a result of this low consumption rate, the tubular dimensions remain nearly constant during the design life of the anode — providing a consistently low resistance anode.

By increasing the length of our tubular anode, yet reducing total current output, De Nora has created another reliable mixed metal oxide anode product line with even greater cost savings over competitive anode technologies. As with all of De Nora mixed metal oxide tubular anodes, the combination of a tough and lightweight product, its ease of handling and installation, the superior mechanical connection, and our fi ve year, no hassle warranty, makes LIDA One the ONE anode for unparalleled Cathodic Protection performance.

FeaturesDesigned to be used as a single anodeDurable — no breakage or damage while getting it to the job siteSpecial crimped moisture seal to prevent damage to electrical connectionNo lead — no epoxy potting compoundsFive Year Product Warranty

P L A T I N I Z E D A N O D E SCorrpro® Platinized Niobium / Titanium Probe Anodes

For Confi ned Installation AreasIn steel vessels, such as condenser water boxes, heat exchangers and heat treaters, where access is diffi cult and space is limited, Corrpro manufactures platinized probe anodes for thru-shell mounting. The anodes are made using either titanium or niobium-rod substrates which are covered with a platinum coating. An oxidizing fi lm inherently coats the surface of titanium and niobium, assuring that the substrates will remain stable, and will not change shape or be consumed during operation. The fi lm also makes the substrate surface relatively nonconductive, and electrical discharge therefore occurs across the platinum coating. The coating is electroplated to the substrates in thicknesses ranging from 100 to 300 micro-inches, and is consumed at a rate of 8 to 16 mg/amp-yr in salt water environments. The recommended current density for both types of probe anodes is between 50 and 300 amp/ft2 in salt water electrolytes. The voltage across the titanium or niobium at the electrolyte interface, however, should not exceed the breakdown voltage of the protective oxide.

Corrpro probe anodes are manufactued with a proven thru-shell assembly. The assembly consists of a stainless steel nipple fi lled with a moisture resistant sealant. Once the anode is placed in this metal nipple and fi lled with the sealant, it is then bonded with G-10 fi berglass. The fi berglass resists water fl ow and lends extra support to the anode. Prior to shipping, each anode connection is pressure tested to ensure a tight seal. The anodes are also adaptable for mounting while the vessel is under pressure.

Chemical CompositionElement Content % of DiameterCopper 79.5Niobium 19.5Platinum Less than 1%

ApplicationsProbe anodes are designed for use in heater treaters, pressure vessels, condenser water boxes, and other aqueous processing tanks where high temperatures and pressures may exist. The two types of substrates, niobium and titanium, provide Corrpro probe anodes with exceptional resilience. They also permit the anodes to operate in temperatures up to 347°F 175°C, and to perform well in chloride environments. Neither type should be used in highly acidic electrolytes.

Ordering ProcedureCorrpro probe anodes are custom made to the customer’s specifi cations. To order the required anode for your structure, indicate that you need a platinized niobium or titanium probe anode. Specify the quanity desired, and anode diameter, length and platinum thickness, along with the G-10 fi berglass length, the fi tting diameter and length. Probe anodes are available solid or copper cored. An example is provided below to illustrate this process.

P L A T I N I Z E D A N O D E SCorrpro® Platinized Niobium Wire Anodes

Protection for Water Storage TanksWaterworks facilities are constantly under attack from corrosion. To combat this process in water and wastewater storage tanks, Corrpro offers a platinized niobium wire anode. The anode is constructed of a copper core, which is surrounded by a niobium substrate. Metallurgically bonded to the substrate is a platinum coating. By using these three metals in combination, an anode with superior protection characteristics is produced. Corrpro’s wire anode is highly conductive and can be operated at a maximum current density of 100 amps/ft2. The anode is also very lightweight, fl exible, and strong. Because the niobium substrate is resistant to corrosion, the anode remains dimensionally stable over its operating life and consumption of the platinum coating is extremely low 40 to 80 milligrams/amp-yr.

Corrpro wire anodes can be used in numerous geometries. In water storage tanks and wastewater clarifi ers, the anode is often suspended by rope in confi gurations which follow the circumferences of the structure. This design permits even current distribution. It also produces a cathodic protection system that is not susceptible to damage from icing. Because the anode is a continuous wire, failures due to poor wire connections are eliminated.

Chemical CompositionElement Content % of DiameterCopper 79.5%Niobium 19.5%Platinum Less than 1%

ApplicationsCorrpro platinized niobium wire anodes are designed for use in all types of aqueous storage and process equipment. The anode has proven to operate effectively in fresh, brackish and salt water, and is not adversely affected by high chloride concentrations. Because of its low consumption rate, the anode may be employed in a cathodic protection system to achieve a design life of 20 years or more.

Ordering ProcedureThe platinized wire anode is available in different platinum coating thicknesses. To order the required anode for your structure, indicate that you need a platinized niobium wire anode, and specify the linear feet desired and the wire type.

L I N E A R A N O D E SCorrpro CorrFlex®

Rugged and Easy to InstallCorrpro’s CorrFlex anode system brings together the lightweight and high performance characteristics of copper-cored, mixed metal oxide anodes with a rugged, fi eld-tested fabric jacket fi lled with calcined petroleum coke. CorrFlex is factory assembled to the highest quality standards that only Corrpro products can claim.

Corrpro offers a full line of CorrFlex anode systems that can be custom designed to suit virtually any linear anode application. CorrFlex utilizes copper-cored, mixed-metal oxide, and titanium based anodes that enhance the linear conductivity of the anode element. Because the mixed metal oxide anode is surrounded by high carbon content powder backfi ll, the CorrFlex anode system can be installed without the need for additional carbonaceous backfi ll. Connections to the continuous insulated conductor are made redundantly every 50 feet, further ensuring a minimum voltage drop along the entire anode length. CorrFlex systems come standard with 40 feet 12.2m of insulated conductor “pigtails” at each end, to allow for bi-directional power feeds.

The proprietary CorrFlex manufacturing process assures that the anode assembly is centered in the backfi ll. The outer jacket of the CorrFlex package is a chlorine/low pH resistant porous fabric that is covered with a protective cross braid for superior abrasion and damage resistance.

CorrFlex comes standard in 1,640-foot 500m lengths. Custom lengths can also be made to order. The continuous standard cable is #8 or #6 AWG, seven strand copper cable with chlorine resistant HALAR insulation. The overall nominal diameter of the CorrFlex packaged system is 1-3/8 inches 35mm.

ApplicationsCorrFlex anode systems perform well in virtually any environment. The anodes can be installed as an integral part of a cathodic protection system for such structures as above-ground storage tanks, pipelines, congested petrochemical facilities and power plants. Trench, cable plow and directional bore can be used to install CorrFlex.

The alloy contains nominal percentages of indium, zinc and silicon. This combined with the anode’s unique shape, allows Corrpro’s cylindrical anode to offer one of the best current outputs available. The chemical composition has a proven track record for delivering superior protection in produced brines even at elevated temperatures.

All Corrpro cylindrical anodes are cast with eyebolt, rod or threaded steel pipe cores. A stabilizing rod attached to these cores ensures a strong mechanical bond between the core and anode.

A L U M I N U M A N O D E SCorrpro® Hull and Special Application Cast Aluminum Anodes

Economical Marine Vessel ProtectionIn salt water environments, where electrical resistivities are usually quite low, aluminum anodes are the most economical choice for corrosion protection. These anodes offer higher current effi ciency and lower anode consumption than both magnesium and zinc in aqueous saline areas, making aluminum ideal for the protection of ship hulls on oceangoing vessels. Corrpro Offers an entire line of hull anodes made of two alloys. Alloy I produces an open curcuit potential of 1.05 volts with respect to a Ag/AgCl reference cell, and realizes a 95% current effi ciency. Alloy Type 3 generates a potential of 1.10, and has a lower current effi ciency rating of 87% in free-fl owing water. This anode material also performs better in saline mud and lower-chloride water. Because Alloy Type 3 has a more powerful driving voltage, fewer anodes are necessary to protect a given structure when elongated shapes are employed.

Both hull anodes are cast with steel core brackets for bolt or weld mounting. They are molded with tapered ends to minimize water turbulence. To ensure quality, each production run of these anodes is inspected for correct chemical compostion through a variety of tests. Electrochemical tests are also employed to verify performance characteristics.

ApplicationCorrpro hull anodes are manufactured for the hulls of oceangoing vessels. They are also applicable for use on any other saltwater structure. Aluminum 3 Alloy contains small amounts of indium, silicon, and zinc; and is especially effective in saline mud and lower chloride water. This alloy is also the recommended protective material for produced water and treatment tanks.

Ordering ProcedureThere are a number of different types of hull anodes that are readily available from Corrpro’s warehouses. To order the required anode for your structure, indicate that you need an aluminum hull anode, and specify the quantity desired, alloy grade, anode type, and confi guration. All anodes are shipped with welded-style mounting brackets unless otherwise specifi ed. An example is provided to illustrate this process.

ApplicationsCorrpro aluminum platform anodes are designed specifi cally for use on production platforms. The two alloy compositions deliver effective cathodic protection in salt water environments. In situations where the anode will be buried in saline mud or exposed to water with lower chloride levels, the Alloy IlI anode will provide more current and better protection. Additionally, since Alloy I contains a slight amount of mercury, it should not be employed in restricted water fl ow areas where concentrated levels of mercury can accumulate.

Ordering ProcedureCorrpro aluminum platform anodes are manufactured in a number of anode weights and core confi gurations. To order the required anode for your structure, indicate that you need an aluminum platform anode, and specify the quantity desired, alloy grade, anode type, and core confi guration. All platform anodes are shipped standard with Schedule 80 pipe cores unless otherwise specifi ed. An example is provided to illustrate this process.

Powerful Protection for Massive StructuresSalt water is a hostile environment for the submerged metal supports on offshore platforms. To defend against this corrosive environment, Corrpro offers a full line of large cast aluminum anodes that are made to two alloying standards.

Alloy I has an open circuit potential of 1.05V with respect to an Ag/AgCl reference cell, with a current capacity of 1280 amp-hrs/lb in salt water. Alloy IIl generates a higher open circuit potential of 1.10 volts with a current capacity of 1150 amp-hrs/lb in salt water. The composition contains nominal additions of indium, silicon and zinc which help to guard against the build up of passive fi lms around the anode. This is especially important in saline muds and brackish waters. In these environments, the Alloy lII anode out-performs the Alloy I anode by providing greater current output.

Both types of anodes are manufactured with steel cores made from heavy weight Schedule 80 pipe. The pipe can be supplied in a wide variety of core confi gurations to accommodate numerous specifi cations and applications.

M A G N E S I U M A N O D E SCorrpro® Extruded Rod and Ribbon Magnesium Anodes

For Specialized ProtectionMagnesium anodes have the highest protection capability of any galvanic material. While these anodes are most commonly used in a cast form, certain structures can be better protected through the use of extruded magnesium confi gurations. Extruded magnesium anodes have high surface and length ratios in relation to cross-sectional area. This allows these anodes to deliver a greater amount of current per weight than their cast magnesium counterparts. By supplying more current, extruded anodes can deliver effective protection to structures buried in even higher resistivity electrolytes.

Corrpro offers a full line of certifi ed extruded magnesium anodes in both rod and ribbon forms. Certifi ed rod anodes from Corrpro are available in high potential 1.75 - 1.77 volts and standard 1.4 - 1.5 volts alloys. They are furnished with a variety of connection options, and are offered in numerous diameters. Corrpro ribbon anodes are manufactured in 3/8” x 3/4” fl exible coils, which can be easily shaped for use on a multitude of projects. The resilient ribbon anode is composed of a high-potential alloy, which produces an open circuit potential of 1.75 - 1.77 volts. Both the rod and ribbon anodes are constructed with a solid steel core, which runs lengthwise through the anodes for effi cient electrical discharge.

ApplicationsExtruded magnesium anodes are most suitable for structures buried or submerged in high-resistivity electrolytes. The rod-shaped anodes, with the small diameters, are often used in commercial and industrial water heaters and storage tanks, or driven into the ground to protect gas service risers. The ribbon anode is used for the protection of pipelines and storage tanks. Extruded anodes are also employed to pre-polarize offshore structures that are to be protected with aluminum anodes.

M A G N E S I U M A N O D E SCorrpro® High Potential Cast Magnesium Anodes

Delivering Superior Protection Power in galvanic cathodic protection is generated by the anode. With Corrpro’s line of high potential anodes, you get the most powerful protection available today. Cast from high-purity magnesium, these anodes produce an open circuit potential of 1.75-1.77 volts, which is 20-30 percent greater than conventional magnesium anodes. This high driving voltage means greater protection can be delivered from fewer anodes. Effi ciency of the anode is enhanced even further when installed in a backfi ll of 75% gypsum, 20% bentonite, and 5% sodium sulfate. This special mixture lowers anode-to-earth resistance, and allows electrical current to fl ow more easily to the targeted structure.

Corrpro certifi ed high potential anodes are manufactured according to strict quality control standards. Each production run of high potential anodes is subject to G-97 analysis. This ensures the anodes you purchase will perform as specifi ed.

ApplicationsHigh potential anodes can be used to protect most buried metallic structures found in a range of soil resistivities. Because they produce a higher driving voltage than conventional magnesium anodes, they are ideally suited for structures buried in soils with resistivities in excess of 2,000 ohm-cm, or containing numerous corrosion “hot-spots”.

Ordering ProcedureCertifi ed high potential anodes are manufactured in a variety of dimensions and weights. To order the required anode for your structure, indicate that you need high potential magnesium anodes, and specify the quantity desired, the anode type, and whether they should be packaged or bare.

Magnesium Balance

ApplicationsH-1 anodes are recommended for use in low-resistivity soils typically below 2,000 ohm-cm. Because the anodes have a lower driving voltage than high-potential anodes, they are ideally suited for structures where over protection is of concern. Their lower-current output also allows these anodes to operate longer than their high potential counterparts in more conductive environments.

Ordering ProcedureTo order the required anode for your structure, indicate that you need alloy anodes and specify the quantity desired, the anode type, and whether they should be packaged or bare. All H-1 anodes are shipped standard in with 10 ft - #12 solid TW lead wire unless otherwise specifi ed. Standard backfi ll composition consists of 75% gypsum, 20% bentonite, and 5% sodium sulphate.

Z I N C A N O D E SCorrpro® Hull, Ballast Tank and Condenser Cast Zinc Anodes

Stopping corrosion begins with selecting an appropriate protection material. On many marine type structures, this material is zinc. To address the demand for this protective material, Corrpro offers hull, ballast tank, and condenser zinc anodes for use on structures in brackish and salt water environments. The anodes are cast using 99.99% pure high-grade zinc, and the ASTM-B-418, Type I chemical composition standard. Through the addition of nominal percentages of aluminum and cadmium, Corrpro zinc anodes are resistant to the formation of zinc oxide around the anode surface, which restricts current fl ow and can shorten anode life. Their unique composition also allows for a current capacity of 354 amp-hr/lb, and an open circuit voltage of 1.05 with respect to an Ag/AgCl reference cell.

All Corrpro marine zinc anodes are manufactured using galvanized steel cores. By galvanizing the cores, a stronger bond is created, thus minimizing the chance for core separation. The cores are available in strap, pipe, or rod confi gurations, allowing numerous mounting possibilities. Other measures taken to ensure quality include the performance of chemical analysis and electrochemical tests.

Z I N C A N O D E SCorrpro® Marine Pipeline Bracelet Zinc Anodes

Zinc anodes have a proven track record for delivering long life protection in marine environments. This is especially true for marine pipelines found in both fresh and saline mud where effective protection can be provided by Corrpro’s zinc bracelet anodes. These anodes are cast to meet military specifi cation MIL-A-18001. They produce an open circuit voltage of 1.05 with respect to an Ag/AgCl reference cell, and are 90% effi cient. Although zinc has a lower per pound current capacity 354 amp-hrs/lb than most conventional aluminum anodes, zinc and aluminum bracelet anodes of identical size will deliver very similar protection, due to the fact that zinc is 2.6 times more dense than aluminum. The chemical composition of Corrpro’s bracelet anodes also allows for better protection against the formation of passive fi lms which can restrict current fl ow.

To better address a wide variety of installation possibilities, Corrpro manufactures two types of bracelet anodes: Semi-cylindrical and multi-segmented. Semi-cylindrical anodes are most often installed on smaller diameter pipe, while multi-segmented anodes typically used on larger pipe. Both types are manufactured with welded galvanized steel cores, and are coated on the pipe side of the anode with coal tar epoxy to enhance performance.



Zinc Balance

ApplicationsCorrpro zinc bracelet anodes are designed for use on all types of pipelines in fresh, brackish and salt water environments. On pipe installations where a concrete weight coat is to be employed, square-ended bracelet anodes are recommended for the creation of a uniform surface. Tapered anodes should be used on all other pipeline installations to minimize problems with offl oading by barge rollers. Zinc anodes should not be used in areas where the temperature may exceed 140°F.

Ordering ProcedureBracelet anodes from Corrpro are manufactured in both multi-segmented and semi-cylindrical stylesMulti-segmented anodes are custom made for each pipeline application. To order semi-cylindrical anodes, indicate the quantity desired, the pipe diameter and the anode dimensions, and whether the anodes should be tapered or square ended.

Z I N C A N O D E SCorrpro® Soil Ribbon Cast and Extruded Zinc Anodes

Effective Protection for Low Resistivity EnvironmentsZinc anodes have been used since the 19th century to protect steel structures from corrosion. Today, these anodes are still widely utilized and have proven to be an effective choice for preventing corrosion in select soils and brackish waters. For these environments, Corrpro offers zinc anodes made to the ASTM-B-418, Type II alloy standard. The anodes generate an open circuit potential of 1.1 volts with respect to a Cu/CuSO4 reference cell. Made from 99.99% pure high-grade zinc, Corrpro zinc anodes offer a 90% current effi ciency, and deliver a current capacity of 335 amp-hrs/lb. This high purity composition also assures the anodes are more resistant to passive fi lms.

Corrpro zinc anodes are available in both cast and extruded forms. The cast anodes are produced in a variety of weights, and are designed for use in low-resistivity soil environments. These anodes are manufactured with lead wires, and are packaged in a backfi ll consiting of 75% gypsum, 20% bentonite and 5% sodium sulfate. Corrpro zinc extruded anodes are produced in diamond-shaped ribbon coils. The elongated shape allows for lower resistance to earth than conventional zinc anodes, and permits easy installation on a multitude of structures.

ApplicationsZinc cast anodes are recommended for use in soils with resistivities below 1,000 ohm-cm. Because these anodes have a driving voltage that is lower than magnesium, they are most effective on well-coated steel structures which require minimal current output. The packaged anodes are commonly

used as grounding cells on electrical motors, panels and conduits, and across insulators on pipelines to limit danerously high voltages. The extruded ribbon anode can be used in buried applications, as well as in fresh, brackish or salt water environments. Neither type of zinc anode should be use in extremely alkaline above 9.2 pH, acidic below 5 pH, or high temperature above 140°F electrolytes.

Ordering ProceduresCorrpro zinc anodes are available in a variety of weights and dimensions. To order the required anode for your structure, indicate that you need a zinc soil or ribbon anode. Specify the quantity or lineal feet desired, alloy composition and the anode model. All soil anodes are shipped standard with 10 feet of #12 solid TW lead wire unless otherwise specifi ed. The ribbon anodes are available in both ASTM Type I and II alloys. The Type I alloy is designed for salt water environments, while the Type II should be used exclusively in soil applications. An example is provided to help illustratrate this process.

Designed exclusively for use in deep cathodic protection anode systems.

AllVent is a product of premium quality designed exclusively for use in deep cathodic protection anode systems.

AllVent has openings placed in a strategic pattern to allow 360º venting ability without a loss of pipe strength. Vertical slits placed with precision cutting wire produce openings 1.5 inches (3.81 cm). With proper installation, AllVent will vent throughout the life of the deep groundbed.

AllVent is of prime importance when sealing is required on the deep anode system. In addition to venting, AllVent can also be utilized as a conduit for adding water should the system require it.

AllVent’s slots are parallel to the longitudinal centerline of the pipe. Center-to-center spacing is 6 inches. Each slot has been placed 1 inch (2.54 cm) in circumferential distance from the preceding slot, allowing for a 360º venting ability. Maximum strength is maintained by placement of openings in this pattern.

Anode Design Tips

When designing deep anode CP systems, limit the current density on the outside of the coke column to a maximum of 150 mA/ft2.

A survey of eight major energy companies operating in the Gulf of Mexico indicated the use of 97% to 99% coating effi ciency for cathodic protection designs on FBE coated pipe over a life from 20 to 40 years.

For AWWA C-301 embedded cylinder, prestressed concrete cylinder pipe PCCP, AWWA C-301 lined cylinder PCCP, and AWWA C-303 pretensioned concrete cylinder pipe, 100 mV of polarization is achieved with a cathodic protection current density of 100 microamps per square foot of outside diameter pipe surface area in most soils.

When designing Grid systems for under above ground tanks that are to be operated at high temperature, specify that the power feeds be provided with Tefl on FEP insulation and the power feed connection be sealed with Tefl on PTFE heat shrink tubing. The cable insulation is rated for maximum continuous service at 205° C and the heat shrink tubing at 250° C.

When designing corrosion protection systems, always include provisions for corrosion monitoring such as corrosion probes, coupons and Permacells.

When using a cathodic protection criteria which results in a polarized potential less negative than -850 mV CSE, recognize that under certain conditions, pipelines experience high pH SCC in the potential range of -650 mV to -750 mV CSE.

For calculating the resistance-to-earth water for slab or bracelet anodes, use McCoys equation:

R = 0.135 P √A

where, R = resistance ohms P = resistivity ohm-cm A = exposed surface area of anode cm²

Petroleum Coke Backfi ll

The Cost Effective Backfi ll MaterialPremium backfi lls with high carbon contents and low contact resistance do not have to be expensive. Alcoke is a quality backfi ll with excellent conductive properties and a very attractive price. It is made from petroleum coke breeze which is calcined to remove hydrocarbons and moisture. The backfi ll possesses a > 97% fi xed carbon content and an uncompacted resistivity of 4.7 ohm-cm. To ensure excellent anode contact, the backfi ll is composed of particles ranging in size from 0.03 - 0.55 inches. This sizing results in a bulk density of 66 lbs/ft3.

Alcoke backfi ll is designed for trouble-free installation. It is supplied in polyethylene bags to protect against moisture intrusion, and pours easily. The backfi ll can be mixed with water for pumping into deep anode beds. Because the backfi ll has a high bulk density and good compaction properties, minimal tamping is required for surface groundbeds.

C O R R P R O ® M E T A L L U R G I C A L G R A D E C O K E B A C K F I L LMetallurgical Grade Coke Backfi ll

For Improved Anode PerformanceImpressed current cathodic protection is an effective method for defending buried metallic structures against corrosion. While some of the anodes used for this type of protection can operate without a backfi ll, the use of a backfi ll will greatly enhance performance. Carbonaceous coke breeze is the material most commonly used for this purpose. This material lowers anode-to-earth resistance, provides a uniform environment for current discharge, and extends the anode’s life. Corrpro impressed current anodes are offered prepackaged in metallurgical grade coke breeze. Corrpro also supplies this same coke breeze separately for large installation projects. This certifi ed backfi ll is composed of fi ne particles ranging in size from 0.02 - 0.375 inch. It possess a high fi xed carbon content which permits good conductivity and a low consumption rate. Because of its unique composition, the backfi ll increases the effective dimensional area of the anode and lowers groundbed resistance for signifi cantly improved performance.

Corrpro metallurgical grade coke breeze is designed for trouble-free installation. It is supplied in bulk for large installations, and in 50 lb bags for smaller projects. Because the backfi ll compacts to a density of 66 lbs/ft3, minimal tamping is required. The backfi ll also has a low moisture content and pours easily.

APPLICATIONSCorrpro metallurgical grade coke breeze is ideal for use in impressed current anode installations where large quantities of backfi ll are required. This includes horizontal anode installations which require a continuous coke column. Because the backfi ll particles are irregularly shaped and contain extremely fi ne carbon particles which can compact and trap gases, it is less effective in deep anode installations.

SHIPPING INFORMATION:Metallurgical coke breeze is shipped in fi fty (50) pound (22.7 kg) coated, woven polypropylene bags. It may be stored outside for limited periods (not to exceed four hundred hours of sunlight). Pallets are available with fi fty bags per pallet

ORDERING PROCEDUREMetallurgical coke breeze supplied by Corrpro is offered in bulk or in 50 lb bags. To order the required quantity for your project, indicate that you need Corrpro metallurgical coke breeze and specify the packaging method and total pounds required. Calculation of the total pounds necessary can be accomplished using the chart provided. An example is also included to help illustrate this process.

Electrical Safety

Electrical hazards can cause burns, shocks and electrocution (death).

Safety TipsAssume that all overhead wires are energized at lethal voltages. Never assume that a wire is

safe to touch even if it is down or appears to be insulated.Never touch a fallen overhead power line. Call the electric utility company to report fallen

electrical lines.Stay at least 10 feet (3 meters) away from overhead wires during cleanup and other activities. If

working at heights or handling long objects, survey the area before starting work for the presence of overhead wires.

If an overhead wire falls across your vehicle while you are driving, stay inside the vehicle and continue to drive away from the line. If the engine stalls, do not leave your vehicle. Warn people

not to touch the vehicle or the wire. Call or ask someone to call the local electric utility company and emergency services.

Never operate electrical equipment while you are standing in water. Never repair electrical cords or equipment unless qualifi ed and authorized.

Have a qualifi ed electrician inspect electrical equipment that has gotten wet before energizing it. If working in damp locations, inspect electric cords and equipment to ensure that they are in

good condition and free of defects, and use a ground-fault circuit interrupter (GFCI). Always use caution when working near electricity.

L O R E S C O ® C A T H O D I C P R O T E C T I O N P R O D U C T SLoresco SC-3® Super Conducting Earth Contact Backfi ll

SC-3 is the fi nest earth contact backfi ll in the Loresco line of products. Loresco is already acknowledged around the world as a leader in cathodic protection. A dramatic breakthough in over thirty years of research has now produced a super-conducting, premium earth contact backfi ll, called Loresco SC-3. Loresco defi nes the standard for quality and performance in the cathodic protection industry.

Loresco type SC-3 is designed specifi cally for demanding anode systems which mandate a low resistivity medium. SC-3 is a dust-free product and according to EPA extraction tests, is extremely pure and complies with regulations governing buried products. A modifi ed industrial standard method for testing permeability (API RP-27) demonstrates that SC-3 will mitigate fl uid interchange between aquifers. Loresco SC-3 is produced specifi cally for cathodic protection applications using an exclusive multi-step process.

First, a high quality base carbon with desired characteristics is selected. Next, this carbon is calcined to a minimum temperature of 1250° C under exacting and controlled conditions. This step results in semi-graphitized carbon particles with excellent conductivity. Then, to further improve bulk conductivity, the surfaces of the individual particles are modifi ed to enhance the contact conductance. This breakthrough in surface alteration ensures maximum electronic current transfer with positive anode contact. Finally, a specially formulated surfactant is added to reduce particle surface tension compaction and settling under water.

Loresco SC-3 has a bulk density of 74 lbs. per cubic foot. The fi xed carbon content is greater than 99% by weight. The bulk density and high fi xed carbon content coupled with the assured low resistivity allows for longer groundbed life at a lower operating cost.

Installation:Loresco SC-3, due to its dust-free manufacture, is simple to install by either mixing and pumping or by pouring. With deep anode systems, pumping from the bottom up is recommended. Loresco SC-3 has superb pumping qualities due to the addition of surfactants and when agitated in water, takes on the characteristics of heavy drilling mud. A recommended mix is seven gallons of water per one hundred pounds. After installing SC-3, allow twenty-four hours settling time before energizing. The modifi ed surface of the carbon particles coupled with the action of the surfactants in SC-3 will achieve positive electrical contact by settling. Vibrating or compacting is not necessary.

Material Description:Loresco SC-3 is a surface modifi ed, blended, and sized carbon backfi ll with surfactants.

Loresco type DW-1 is designed for impressed current surface systems and light duty semi-deep anode systems.

Loresco type DW-1 is a sized carbon backfi ll with particles ranging between 0.004” to 0.04”. DW-1 weighs seventy-four pounds per cubic foot and sinks readily in water or light mud. The fi xed carbon content of DW-1 is over ninety-nine percent.

Being a sized and predominantly round material, DW-1 may be installed by either pumping or pouring. Approximately seven gallons of water per one hundred pounds of backfi ll should be utilized when pumping. DW-1 wets easily and only minimum agitation is necessary before pumping.

Specifi cations:Fixed carbon 99.35%Ash 0.6%Moisture 0.05%Volatiles nil (950°C)*Bulk density 74 lbs. per cubic footParticle sizing ranging from 0.004” to 0.04”



Installation:Loresco DW-1 may be poured freely into dry applications. Tamping is not required. When it is

applied by pumping, the recommended method is to pump from the bottom of the bored hole upward. After the application pipe (a one-inch steel pipe) is lowered down to the bottom of the bored hole, it is coupled to a 20 GPM pump with a minimum capacity of 250 psi. Normally, the application pipe does not have to be raised during pumping procedures.

Horizontal Installation Procedure:Have a reasonably clean ditch (design usually calls for a ditch one foot wide). Pour Loresco DW-1 in a continuous layer six inches deep (or as specifi ed). Place anodes on top of DW-1. Pour DW-1 in a continuous layer six inches deep until anodes are covered by a six inch backfi ll cover (or as specifi ed). Fill the remainder of the ditch as specifi ed.

Vertical Installation Procedure:Have a reasonably clean hole (depth depending on soil resistivity). Place one foot of DW-1 in bottom of hole. Lower and center anode in proper position. Pour DW-1 over anode until design level is reached. Fill remainder of hole as design specifi es.

Shipping Data:Loresco DW-1 is shipped in fi fty (50) pound (22.7 kg) coated, woven polypropylene bags. DW-1 may be stored outside for limited periods (not to exceed four hundred hours of sunlight). Pallets are available with fi fty bags per pallet. Proven export packaging is also available.

L O R E S C O ® D E E P A N O D E S Y S T E M SLoresco PermaPlug Environmental Earth Seal

PermaPlug has been designed especially for the cathodic protection industry. PermaPlug provides the cathodic protection industry with a method to plug and seal earth holes. PermaPlug is environmentally safe and when properly installed, prevents the contamination of underground aquifers from surface fl uids.

PermaPlug produces a permanent non-porous molding-clay seal. Manufactured from naturally occurring Bentonite, PermaPlug contains no additional chemicals. Installation is easy requiring no tools or pumps. Simply open the bag and pour.

PermaPlug prevents the deterioration of underground water quality and is environmentally accepted for use in the vicinity of potable drinking water.

PermaPlug requires minimum instruction for proper application. PermaPlug is inexpensive, easy-to-install, requires no special tools, and...it works!

Application Data:Condition the earth hole area to be sealed by fl ushing with clean water or by allowing any drilling fl uids to suffi ciently thin by overnight settling. The fl uid within the earth hole should allow the PermaPlug particles to sink readily. When installing PermaPlug above carbon backfi ll, ensure complete backfi ll settling before beginning PermaPlug installation. Pour PermaPlug slowly into earth. Install one 50 lb. bags of PermaPlug every 3 to 4 minutes until the desired level is obtained.

Once in place, PermaPlug will expand to seal the earth hole. PermaPlug is shipped on stretch wrapped pallets. Each pallet contains 3,500 lbs of PermaPlug. Material should not be handled roughly before installation as fracturing of particles will occur. PermaPlug is shipped in water-resistant bags but must be stored out of the weather due to moisture sensitivity.

C O R R P R O ® B A C K F I L L A C C E S S O R I E SCorrpro® Spira-Pak

The Right Way to Pack AnodesCoke breeze backfi lls provide a homogenous environment for impressed current anodes and can substantially lower groundbed resistance by twenty, thirty, or even forty percent. Spira-Pak anode canisters developed by Corrpro ensure the anodes are evenly surrounded with the proper amount of coke breeze backfi ll. They are constructed from galvanized steel and can be used with cast iron, graphite or mixed metal oxide anodes. Because the canisters are made by mechanically crimping narrow strips of the galvanized metal in a spiral pattern, the Spira-Pak canisters are signifi cantly stronger than the old “stove pipe” cans. This allows them to stand up to rough handling during shipping and installation. Even backfi ll compaction is assured since the cans are vibrated during fi lling to obtain the optimal material density.

Spira-Pak canisters are offered in 4, 6 , 8 and 10 - inch diameters. They can be made to virtually any length and are sealed at either end by grooved wooden plugs. Use of the backfi ll canisters not only reduces installation costs, it also saves time and coke breeze.

Typical ApplicationsCorrpro Spira-Pak canisters are designed for pre-packaging impressed current anodes in coke breeze backfi lls. They are ideal for wet and marshy environments where the fi eld installation of coke breeze is diffi cult. The canisters ensure even coke breeze compaction and a homogenous environment for superior current discharge.

Ordering ProcedureAll of the impressed current anodes offered by Corrpro may be pre-packaged in Spira-Pak canisters. To order your anodes with this specially designed container, simply inform your sales representative at the time the order is placed.

Saves money by reducing installation time Centers anode in groundbed hole Maintains proper spacing between anode and non-conductive vent pipeIncreases anode life by ensuring backfi ll coverage on total anode surface areaSolid, sturdy construction prevents bending or breakage during installationSmooth, round surfaces guide anode and vent pipe down the hole

InstallationThe vent pipe is secured to the Ventralizer with two hose clamps. The other clamp should be attached to the anode -- only on the copper collarsA cordless drill or screwdriver quickly tightens clamps around both the vent pipe and the anodeThe entire anode and vent pipe assembly can then be easily fed down the groundbed holeOn longer anodes, it is recommended that two Ventralizer be used -- at the top and bottom of the anodeOn double tail strings, or LIDA One anodes, the cables from lower anodes should be taped to one of the Ventralizer arms to keep the cable away from the anode

Ventralizer™Get The Most Out Of Your Groundbed. Maximize Your Anode Current Output. Minimize Resistance.

The purpose of an impressed current anode in a groundbed is to electronically conduct current. In order for this to work, it is critical that the anode be surrounded by well compacted carbonaceous backfi ll.

In the installation of LIDA® tubular anodes, a common practice is to “tape” the anodes to the vent pipe -- feeding a single assembly down the hole. However, this can result in the anode being too close to the vent pipe to allow the backfi ll to fi ll around the entire anode surface during pumping operations. The non-conductive vent pipe can also serve to shield portions of the anode in contact with it, resulting in uneven current discharge the anode.

To attach the LIDA® tubular anodes to the vent pipe, yet allow suffi cient spacing between the anode and vent pipe, the Ventralizer™ has been developed.

The Ventralizer’s™ dual function is to centralize the anode in the hole, and at the same time, provide 1” of separation between the anode and the vent pipe.Benefi ts
