Impressed Current Anode
Impressed current cathodic protection is an effective method to prevent corrosion of underground metal structures such as pipelines, tanks and so on.
The auxiliary anode is and important part of the impressed current system, which transfers the protective current to the surface of the protected structure through the medium.
The underground structures impressed current cathodic protection anode usually does not directly be buried in the soil, but form the anode ground bed through filling the carbonaceous filler around the anode. The filler is used to decrease the grounding resistance of anode ground bed and prolong the service life of the anode.
 
Classification of Impressed Current Anodes
1. Prepackaged High Silicon Cast Iron Anode
A. Composition: Prepackaged high silicon cast iron anode is mainly composed of anode, filler coke, air guide pipe and the steel casing pipes and so on.
B. Performance: low consumption rate, low grounding resistance, stable output current and voltage, convenient construction; widely used in cathodic protection construction.
C. Application: auxiliary anode for impressed current cathodic protection system.
D. The anode is deep into several tens of meters of wet soil, effectively reducing the grounding resistance, greatly improve the coverage of the cathodic protection system and extending the life of underground structures such as pipelines. This anode also saves the operation and maintenance cost of cathodic protection system. It is an ideal cathodic protection material for high soil resistivity.
