Anodes are utilized for the prevention of corrosion in underground piping systems. An anode (sacrificial) is an assembly consisting of a bag which contains magnesium or zinc ingot and other chemicals. The bag is connected by a wire to an underground metal piping system. The anode functions as a battery that impresses a direct current on the piping system to delay the process of corrosion. The magnesium or zinc will sacrifice itself through its own corrosion to reduce/delay corrosion in the steel pipe. At SiteWise, we install anodes daily as a routine practice in the construction, reconstruction, and repair of natural gas distribution facilities. For corrective maintenance applications, we offer “key holing” installation of anodes in high traffic areas, under asphalt or extremely deep pipelines. This innovative method is a cost saving process for our customers.
