Insulation Flange Gasket 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.
Type “D” insulation gaskets are available for RTJ flanges but the KXT-150 Sealing Gasket is an excellent alternative to “D” gaskets because the sealing element may be positioned anywhere between the I.D. of the gasket and I.D. of the ring groove.
