Pipeline Flange Isolation Kits are used for controlling losses due to corrosion. They can be used to control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems. Application of Pipeline Flange Isolation Kits • To limit the extent and cost of cathodic protection current to only those pipes that need to be protected from the main cathodic protection system • To electrically "split up" long pipelines into distinctive cathodic protection systems • To isolate a pipeline to ensure that cathodic protection or stray electricity currents do not cause increased corrosion, or cause a hazard • To isolate piping systems where dissimilar metals are present • To eliminate static loading charge transfer in discharge or loading operations at oil storage terminals Gasket Type: Type E (Full Face Gasket) This gasket kit provides complete protection of both flange faces. The gasket has same outside diameter of flanges. This feature will prevent collection of foreign matter between the flange faces to ensure complete cathodic isolation. Type F (Ring Gasket) This gasket is manufactured to fit only the raised face surface of the flanges. Outside diameter of the gasket is designed to be slightly less than the inside diameter of the bolt circle. It is recommended that the flanges be wrapped to prevent foreign material from "shorting out" the flanges. Type D (RTJ Gaskets) To fit RTJ flanges.
