High Silicon Iron Anodes for Cathodic Protection

Product Detail

Product Description

High Silicon Cast Iron (HSCI) Anode is the buried component of impressed current systems for cathodic protection of land and marine structures from corrosion.

HSCI is working well for electrical conductivity. Impressed current anode that will form a thin passive barrier film of silicon dioxide on the metal surface, after oxidation takes place. The film has high resistivity and chemistry stability, which is in passive state under acid conditions, so it can reduce the dissolving rate for anode.

Moreover, after covered by Chromium, the protection film of SiO2 of HSCI is develped to resist corrosion from alkali and chloride ion, so that anode can be applied for strong choloride conditions. Therefore, HSCI Anode with Chromium adapts to all kinds of land and water environments.


    1)High corrosion resistant capacity 

    2)High electrical conductivity 

    3)Conform to ASTM A 518M Gr3.

       HSCI Solid Stick Anode works well for Impressed Current Cathodic Protection of Offshore platform, underground steel oil tube, underground cables, subsea pipelines, etc. The chemistry of HSCI for impressed current anodes is well established in Standards, and it results in superior corrosion resistant capacity for mechanical properties.

       Our company supplies Single Head HSCI Stick Anode and Double Heads HSCI Stick Anode, based upon the shape of our stick anode. For cable connection means, we have HSCI Stick Anode with embedded seamless pipe, HSCI Stick Anode with embedded bolt and HSCI Stick Anode with caulking lead. Depending on customer's requirements, we can supply HSCI Anode installed with cable or otherwise.

    Chill Casting is the dominant method for our anode products with more consistent weight, greater density and better performance. 

       As follows is the Product Specification of our Double-ended Stick Anodes with leaded connection. Please note that the data are nominal and can be modified in accordance with customer's drawings and requirements.
