Sometimes galvanic cathodic protection isn’t enough, such as when stray electrical currents from nearby power sources cause a structure (e.g., a pipeline) to corrode. Impressed current cathodic protection (ICCP) is an appropriate solution in these situations. This educational video from CorrConnect covers how impressed current cathodic protection succeeds where other methods fall short. Check it out!
Video: When to Use Impressed Current Cathodic Protection
Takeaway: Impressed current cathodic protection (ICCP) is necessary when stray electrical currents threaten to corrode metal equipment.
