Silicon Iron Anode

Silicon Iron Anode

Description:
Corroco designed and produced solid or tubular silicon iron anodes for the effective cathodic protection for underground and underwater structures by the impressed current method. This high silicon cast iron anode (high silicon iron tubular anode) is manufactured from high silicon cast iron alloy, which is one of the most effective anode materials in various environments. It can be installed in deep ground bed, seawater or brackish water. CORROCO adopts the metal mould casting technology to produce high-quality alloys.

Suitable Installation:
Deep ground beds;
Seawater or brackish water;
With or without carbon backfill;
With or without canisters
