ANODE BEDS

AB.SК ТU 3435-011-09890805-2015

FUNCTION

Anode beds (AB.SК) are designed for using them as the low-soluble elements of the anode beds connecting the positive terminal of an alternator of CPS with the ground and for providing protective currents exhaust into the ground.

GENERAL CHARACTERISTICS:
  • High operational period.
  • An anode bed is provided with a corrosion resistant cable which is used in CPS.
  • Several modifications of the device used for different environment conditions.
  • Safe anchoring and airtight packing of the connecting point of the lead cable and of the operational electrode.

 FOUR GENERAL MODIFICATIONS OF THE ANODE BEDS AB.SK ARE PRODUCED:

SAB.SK.FS – surface anode beds;

SSAB.SК.FS – standard surface anode beds;

DSAB.SК.FS – deep-seated anode bed;

SBDAB.SК.FS – standard block deep-seated anode beds.

Anode beds AB.SK.FS meet General Technical Requirements GTR ОТТ-29.100.99-КТН-163-12 change 2 “The Main Pipeline Transportation of Oil an Oil Products. Cathode Protection Systems.Anode beds”. They are included into “The General Product Type Register” bought by PJSC “Transneft”.

The anode bed AB.SK. is produced by using a method of special corrosion resistant foundry FS 15 (iron silicon) according to GOST 7769.  In case of high chloride content or sea water content the foundry becomes alloyed by chrome which increases its resistance.

SSAB.SК.FS are delivered in the kit. They are delivered in a metal tube filled with a mineral activator. An anode layer activator significantly increases a connecting current-drainage space and this process makes transient resistance “operational electrode – ground” low as well as protective current spreading.
