Mitigating AC Corrosion on Cathodically Protected Pipelines

It’s becoming more common for pipelines ? even cathodically protected ones ? to experience external corrosion due to induced alternating current. This induced AC corrosion can be difficult to detect, let alone control, without an understanding of what it is and how it occurs. This article covers the fundamental concepts behind this unique type of corrosion, along with strategies for controlling it and protecting pipeline personnel from AC-related safety hazards. <strong>Key Facts About Induced AC Corrosion</strong>
