Copper Core Linear Anode for Cathodic Protection System
Anode-flex (Flexible Anode) is the core component of the cathodic protection system. It is a linear, flexible and carbon based anode system, being installed in the pipeline, tanks, or other protected structure nearby, and connected to the anode which is connected with external power supply, while the oil tank and pipeline are connected to the negative electrode of the external power supply to form a circuit. After power on, the right amount of protection current can be evenly dispersed through the wire to each part so that the protected body is fully protected.
 
Copper cable core: used as current conductor, the cable type anode has good flexibility, strong resistance to mechanical damage and good chemical stability. With 12.7mm outside diameter of cable and 11.4mm2 sectional area of internal copper core wire, the resistance of unit length R’ is 2mΩ.m-1. Flexible anode is mainly used for the cathodic protection of buried pipeline and tank bottom.
 
The application of flexible anode successfully resolves the problem of old pipeline cathodic protection and also can generally solve the difficulty of some conventional cathodic protection technology such as interference of external structure, the implementation of cathodic protection problems in high resistivity environment medium, cathodic protection current distribution at tank bottom.
 
Generally flexible anode has the following components
Copper core, conductive polymer anode materials, coke residue, basketwork and so on.
