Inline Cathodic Protection: Its All About Current

The external pipeline corrosion control field has seen great change over the years from a regulatory standpoint. However, the field has seen few advances in new technology to assist in monitoring the effectiveness of mitigation efforts. That changed recently with the introduction of an inline inspection (ILI) tool that measures cathodic protection (CP) current flowing on a pipeline. A.W. Peabody stated in his classic book, Control of Pipeline Corrosion, “When the amount of current flowing (to the pipe) is adjusted properly, it will overpower corrosion current discharging from all anodic areas on the pipeline and there will be a net current flow onto the pipe surface at the
