The anodes can become porous during the graphitization process, allowing water penetration, corrosion, and premature failure of the metallic lead wire to anode connector. To overcome these issues, the carbon industry has developed treatments that fill the pores with high-quality non-conductive materials. Scientifically boiled linseed oil, microcrystalline wax, and special resins are used in this process, significantly improving the performance of graphite anodes in wet and hostile environments. Furthermore, the resin treatment strengthens the anodes, making them ideal for deep anode ground beds and "free suspension" applications in water tanks, docks, and piers.
At Global Corrosion, we offer a comprehensive range of high-quality graphite anodes suitable for impressed current cathodic protection systems. Our graphite anodes are available in standard sizes of 3 x 60 inches and 4 x 80 inches, with the option for custom shapes and sizes upon request.
Choose from untreated graphite anodes or those impregnated with microcrystalline wax, double-boiled high-purity linseed oil, or resin. Graphite is an excellent choice for cathodic protection due to its chemical inertness, cost-effectiveness, and excellent electrical conductivity. With the widespread application of cathodic protection, particularly in underground pipelines, utilizing graphite anodes has become a routine and efficient method of corrosion control.
