Cathodic Protection is a key element to ensuring the safe operation of steel pipelines. It is a regulatory and code compliance requirement that pipelines have an external corrosion mitigation program in place. It is also a compliance requirement that cathodic protection systems are maintained and monitored. Cathodic Protection is a proven and cost-effective method to prevent infrastructure failures arising from metal loss. The regulatory bodies of AER, CER, and PHMSA have delivered notices to pipeline operators of the distinction between effective Cathodic Protection and excessive Cathodic Protection, which may promote stress corrosion cracking. This is an important consideration for older pipelines.
