Long anode beads (AB.SK.L) are used in anti-corrosion protection systems:

• main, field and other pipelines and multi-line pipeline systems in any soil: rocky, arid, desert and permafrost, with a specific electrical resistance of more than 350 Ohm / m;

• branched communications of compressor, gas distribution, oil pumping stations, thermal power plants and industrial sites for other purposes;

• underwater crossings of single-line pipelines and their multi-line systems, for linear parts of main pipelines;

• technological tanks for any purpose, including the inner surface, for valve assemblies and pipeline connections;

• port and berthing buildings and structures, platforms and other hydraulic structures.

• Long service life

• Anode beads switch equipped with a corrosion-resistant cable for use in ECP systems

• Availability of several modifications of execution for use in various operating conditions

• Reliable fastening and sealing of the point of contact between the current supply cable and the working electrode

• Relatively low rate of anodic dissolution and, as a consequence, low weight of the working electrode

• Possibility of using in difficult conditions where AE of other types are not installed (for example, the inner surface of tanks)

AB.SK.L are manufactured in two types:

• type 1 (hereinafter AB.SK.L1) with a working element made of an electrically conductive polymer (ethylene-vinyl acetate – 55%, soot – 45%), is a product consisting of a conductive core in a coaxial sheath of an electrically conductive polymer located in a fabric sleeve filled with graphite activator;
• type 2 (hereinafter AB.SK.L2) with a working element based on titanium Grade2 (analogue of VT1-0 according to GOST 19807) coated with MMO, the working element is made in the form of a wire, is a product in which a wire working element and an insulated conductive core are placed side by side in parallel and there are insulated electrical contacts between them with a set pitch of 3 meters, this structure is located in a fabric sleeve filled with a graphite activator

To supply electric current to the working element AE.SK.L type 1 and type 2, a cable is connected.

AE.SK.L for the CP system are manufactured in the following designs:

– standard – for use on the linear part of the main pipelines, technological pipelines of the pump station;

– modular – for use under the bottom of tanks.

Anode beads AB.SK.L meet the general technical requirements OTT-29.100.99-KTN-181-12 rev. 2 “Main pipeline transportation of oil and oil products. Electrochemical protection. Long anodes” and are included in the “Register of the main types of products purchased by PJSC Transneft”.
