Why Dielectric Flanges Matter More Than You Think After spending well over a decade around industrial pipeline gear — from maintenance pits to design rooms — I can say dielectric flanges don’t get quite the spotlight they deserve. Oddly enough, these humble connectors hold a quiet but critical role in preventing galvanic corrosion, which, frankly, can wreck a pipeline faster than you’d guess. For the uninitiated, a dielectric flange acts as an insulating interface between two different metals, blocking electrical contact that could trigger corrosion. When you consider how many pipeline section…
