An oil and gas operator located in Australia approached GPT Industries as they were encountering an issue with two flange connections that were experiencing leakage issues within hours of installation. On closer inspection it became clear that the leakage was not coming from the flange face but was in fact a result of the media permeating through the body of the gasket.

GPT_EVO_Electrical Bridging_06.2022(F)A problem that is becoming more and more common place in industry is electrical bridging. For years, this customer has battled losing isolation across the flange isolation kit, not because of a gasket failure or mis-installation, but instead because of the media itself but instead due to the media itself going through the line. In these lines, solid conductive deposits build up at the flange intersection, allowing CP current to take this path, jumping the isolation kit, and continuing to the next flange.
