Graphite Anode For Cathodic Protection

CORROCO graphite anodes are produced by high quality petrolrum coke. The petroleum coke is mixed with petroleum tar and extruded into rod. After being repeatedly sintered at very high temperature, the rod becomes high density, high carbon concentration, thus have a low consumption when it is used. According to customer's request, our anodes are impregnated by linseed oil or by wax in order to protect the anode from moisture. Graphite anodes can be supplied in following form: 1. Rod, without processing; 2. Rod, hole prepared for cable connection; 3. End connection; 4.Center connection.
