Cathodic protection reduces corrosion in underground gas distribution systems by forcing a DC current onto a metallic structure to counteract any corrosive current flowing from the structure to the earth. Cathodic protection will not prevent corrosion from occurring within the system, but instead transfers it from the protected structure to a sacrificial surface. This replaceable surface is commonly referred to as an anodic structure, anode, or ground bed.
