High Silicon Cast Iron Anode

Intended Use

They are designed for work in cathodic protection schemes for main oil and gas pipelines, underground and surface storage tanks, structures on piles, wells, and other metal structures.
PSS-HSCI impressed current anode is an anode equipped with a cable outlet for connection to the main supply cable from a transformer rectifier.
Anodes operate in any soil and climatic conditions when they are located below the depth of soil freezing.
High silicon cast iron alloy, the most common material for the production of impressed current anodes, has proved itself as a durable and strong material. Such anodes are much stronger than graphite ones.
A distinctive feature of high silicon cast iron anodes is their resistivity to current load.
The arrangement of the anodes can be horizontal or vertical.

Specifications

Rated operational anode current of the anode - 5.0 A.
The contact resistivity of the contact connections shall be no more than 0.05 Ohm
The anode is equipped with a cable outlet with a cross-section of 6 mm 2 or more and a length of 3.0 m designed for a rated voltage of 660 V.
The insulation resistivity of the contact unit is not less than 100 MOhm.

The High Silicon Cast Iron Anodes of the type PSS-HSCI
It is a silicon cast iron anode equipped with a cable outlet for connection to the main supply cable from a transformer rectifier.
The Prepackaged High Silicon Cast Iron Anodes PSS-HSCI-P
It is made in the form of a metal casing in which a silicon cast iron anode is placed, and the free space between the anode and the metal shell is filled with a coke breeze backfill.
The Bundle High Silicon Cast Iron Anodes PSS-HSCI-B
It is supplied as a set of the required number of impressed current anodes with cable-outlets of the required length and main cable.
The Prepackaged Bundle High Silicon Cast Iron Anodes PSS-HSCI-BP
It combines prepackaged anodes with the correct length of cable attached to the main cable at the factory.

The mounting technique of surface anode groundbed depends on the anode installation method (horizontal or vertical positioning) and is determined by the cathodic protection project. Special modifications have been developed for laying at great depth or in a well.

Recommendations for the use and operation of the impressed current anodes

If soil resistivity is from 0 to 10 Ohm * m, it is recommended to use titanium-based impressed current anodes;
If soil resistivity is less than 20 Ohm * m, it is recommended to use metal impressed current anodes;
If soil resistivity is in the range from 20 to 50 Ohm * m, it is recommended to use the silicon cast iron-based impressed current anodes;
If soil resistivity is from 50 to 150 Ohm * m, it is recommended to use polymeric impressed current anodes;
If soil resistivity is more than 150 Ohm * m, it is recommended to use extended impressed current anodes.
