Sacrificial Anode

Description

A sacrificial anode is a metal element installed in electrical contact with a structure or piece of equipment (tanks, heat exchangers, buried pipes, hulls, water heaters) to protect it from corrosion through galvanic cathodic protection. Being more electronegative than the metal it protects, the anode corrodes preferentially, preventing deterioration of the main asset.

This system is used in mining, chemical plants, agribusiness and heavy industry, where exposure to corrosive environments (industrial water, saline soils, chemical processes) significantly shortens the service life of equipment without cathodic protection.
