Flange isolation kits

Flange Isolation Kits For Cathodic Protection

Flange isolation kits: are available for all flange sizes, types, pressure ratings and materials.

flange-isolation-kitsINTRODUCTION: Flange Insulation Gasket Kits prevent electrical conductivity between the flanges.

The kit consists of one Insulating Gasket, one full length insulating sleeve per bolt, two insulating washer per bolt and two metal washer per bolt.


Isolation gaskets are commonly used as an insulator between dissimilar metal flanges for corrosion protection.

Insulating kits isolate electrically pipe sections in cathodic protection systems, to prevent the flow of stray current along the pipelines.

Flange Insulation Gasket Kits are designed to prevent electrical conductivity between the flanges.

Isolating gaskets are suitable for use in Full Face, IBC and RTJ flanges. WA Isolation kits have excellent dielectric properties and superior sealing characteristics. The gasket is suitable for all pressure ratings including ASME B16.5, ASME B16.47, API 6B and API 6BX flanges up to 20,000 PSI

Type "F" raised face gaskets are placed inside the flange bolt circle and seats fully on the raised face of the flange.

Raised face flange type of gaskets are supplied in all the materials, Phenolic and Glass / Epoxy with Neoprene Rubber coating.

Cut sheet Flange Isolation Kits:



Type "E" full face isolation gasket seats with it's outside diameter equal to that of flange OD. The bolts run through the gasket.


INSULATION Gaskets – WA-Very Credical high pressure conditions


High Pressure flange isolation Gaskets: designed for very critical service.


The gasket is suitable for use in Full Face, IBC and RTJ flanges. Excellent dielectric properties and superior sealing characteristics.

Critical isolation gaskets are suitable for all pressure ratings including ASME B16.5, ASME B16.47, API 6B and API 6BX flanges up to 20,000 psi.

Phenolic materials are available on request for low temperature and low pressure services.

High tensile fasteners are available with insulation kit gasket on request with or without Hot Dip Galvanized.

All Standards And Non Standard Dimensions of Insulation Kit Gasket are Available.

Very Critival Fire safe Isolation Kits



Fire safe Gasket Kits are designed for preventing leakage of process fluid and provide insulation during fire.

Insulation Gasket kits have spring energized PTFE seal and an E ring with special high temperature Xylar coating.
