Flange Insulation Gasket Kit

Flange Insulation Gasket Kit

The Flange Insulation Gasket Kit is the most widely used form of controlling losses due to corrosion. Flange Insulation Gasket Kits 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 and confine or eliminate electrolytic corrosion.

Product Description

Flange isolation kits


Flange Isolation Gasket Kits are designed to maintain the integrity and reliability of the pipeline and piping system through safety and corrosion protection.

By eliminating metal to metal contact, static current is halted to prevent corrosion and aid in the Cathodic Protection of the piping system. Flange Isolation Gasket Kits provide both an effective seal and reliable electrical isolation of flanges. Constructed of high quality materials that have a high dielectric constant and low water absorption, our Flange Isolation Gasket Kits are available in various configurations to meet every possible need. We offer Flange Isolation Gasket Kits in all sizes, in all DIN, ASME and API classes. Custom and special sizes are also available upon request.


Gasket kit types 


Type F (Raised Face) This gasket will fit only the raised face surface of the flanges. The outside diameter of the gasket is slightly less than the inside diameter of the bolt circle. This gasket can be used on both raised face and full face flanges. Type F gaskets are available in, neoprene-faced phenolic, and high temperature materials (see below). (It is recommended that the flanges are wrapped with Flange Band Protectors to prevent foreign material from collecting and creating a bridge, thus shorting out the isolation.) 

Type E (Full Face) This style kit contains a full face gasket that has the same outside diameter as the flanges. This style gasket will prevent foreign material from collecting and creating a bridge, thus shorting the cathodic isolation. Type E gaskets are available in, neoprene-faced phenolic, and high temperature materials (see below). 


Type D (RTJ) Type D gaskets are designed to fit into the ring groove of RTJ (ring type joint) flanges. We also offer BX gaskets. Both are available in phenolic.
