Long-line flexible anode for impressed-current cathodic protection of buriedpipelines a n d of on-grade a n d buried storage tanks.
Product description
ANODEFLEX 1500 cathodic protection.
Construction: Five basic elements:
Central Copper Conductor: #6 AWG, serving as a low resistance busbar to deliver the required current over considerable distance without incurring substantial longitudinal voltage drop.
Conductive polymer: 0.5 in (13 mm) in diameter special extrusion, sealing the copper conductor from chemical attack, yet allowing current to flow through it, from the conductor to the environment all along its length.
Coke breeze: Pre-packaged, high performance calcined petroleum coke breeze, serving as the active matrix in which the electrochemical reactions take place. Designed for min. 20 years service life at max. current output of 16 mA/ft (52 mA/m).
Fabric jacket: Integrated woven, acid resistant a n d porous jacket holding the coke breeze in place around the anode.
Protective braid: Tough, porous, non-conductive protective braid enhancing the abrasion a n d damage resistance of the fabric jacket. Anodeflex 1500-1 is a long-line, flexible, cable-like anode, which is placed in continuous close proximity to the target structure. Uniform distribution of cathodic protection current is therefore achieved on applications where many conventional anode ground beds do not work. Key to the product's performance is the central, conductive-polymer coated copper conductor. This unique construction allows current to flow long distances down the center conductor, while allowing sufficient cathodic protection current to continuously pass through the conductive polymer all along the length of the anode. In contrast to conventional CP systems, AnodeFlex is placed in the ground in close proximity to the steel surface to be protected a n d provides uniform distribution of protective current to the entire steel surface, thereby maintaining the steel-to-soil "instant-off" potential in the required window of -850mv (-950mv if SRB's present) a n d -1200mv. The central anode cable is surrounded by factory prepackaged, high conductivity coke breeze, held in place by a porous, woven acid-resistant jacket. This arrangement avoids handling loose coke breeze a n d simplifies field installation. The improved current distribution increases anode efficiency a n d helps prevent over-voltage problems such as hydrogen generation a n d associated rapid coating disbondment. In addition, interference from other structures a n d stray currents are virtually eliminated. On poorly coated pipelines where optimal polarization can no longer be achieved,
Anodeflex 1500-1 can often be installed as an alternative to expensive recoating. Both on single a n d multi-parallel pipelines, safe levels of polarization will be restored at every point. The system avoids difficult a n d costly field recoating a n d greatly reduces environmental disturbance.
AnodeFlex 1500-1 is delivered on long length spools a n d because no additional coke breeze is required, the installation is as simple as laying a low voltage power cable. Proven heat-shrinkable splice kits, Tee joints a n d end sealing caps are available to complete any installation design.
