Cathodic Protection Rectifier Integration When Polyethylene Tanks Coexist With Steel Pipe Networks: Galvanic Isolation, NACE SP0169 Discipline, and the Stray-Current Failure Modes That Surprise Operators
Cathodic protection (CP) is a corrosion-control discipline designed for buried steel: a rectifier drives DC current from anodes to the protected steel structure, the steel cathode polarizes negatively…
