Product Details
Description:
High Silicon Cast Iron Anodes is a form of impressed current anode.It is one of the most effective anode materials in various environments cathodic protection.This anodes can operate effectively in a variety of electrolytes, from soil and freshwater to brackish and salt water environments. Both solid or tubular silicon iron anodes are available in Corroco company
Advantage:
1. High Silicon Iron Anodes can be used in a wide range of application.
2. Low consumption rate of anodes
3. Higher current densities can be applied in fresh or sea water.
Application:
1. Above ground storage tank bottoms
2. Reinforced concrete structures
3. Under ground storge tank
4. Fine sand environment
5. Environment evolution of O2,Cl2 or a combination of both
