Flange Insulation Gsket Sets are usd to solve the sealing and insulating problems of flanges, and to control losses due
to corrosion and leakage of pipelines. They are widely used to seal flanges and control stray electric currents in piping at oil, gas,
water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems.
Application of Flange Insulating Gasket Sets
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
Insulation 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 Type 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. They can be produced according to ASME and API flange standard.
