Product Description
Type D/E/F Flange Isolation Joint Gasket Kit
A flange isolation joint gasket kit (Type D, E, or F) is a specialized component used in pipeline systems to ensure electrical isolation and protect against corrosion at flange connections. Typically, the kit includes gaskets, insulating sleeves, insulating washers, insulating nuts, and insulating bolts.
Type D, E, and F flange isolation joint gaskets are engineered to fit different flange types, with each type featuring a unique shape and size to ensure a precise fit. These gaskets are usually made from materials such as neoprene, EPDM, or nitrile rubber-materials known for their excellent sealing and insulating properties.
This gasket kit is specifically designed for applications where two dissimilar metals are joined, as such connections can create a potential difference that leads to galvanic corrosion. The kit's primary function is to provide electrical insulation between the two metals, thereby preventing this type of corrosion and extending the pipeline system's service life.
In summary, the Type D, E, or F flange isolation joint gasket kit is a specialized solution for pipeline systems, delivering electrical insulation and corrosion protection at flange connections.

We provide a service, manufacturing to our customers requirements. We make the gasket that you need, to meet your specifications in the most economical way. We can manufacture from sample, technical drawing, or electronic file. Our production machinery can manufacture straight from your own technical drawing file.
Insulating Gaskets are used for sealing and isolating flanges to prevent corrosion. They are used for dissimilar material flanges and cathodic protection piplines to control losses due to corrosion. They can be sued to control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems.
Insulating Gaskets Types:
Type E (full face) insulating gasket 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) insulating gasket is manufactured to fit only the raised face surface of the flanges. Outside diameter of the gasket is desinged to be slightly less than the inside diameter of the bolt circle. It it recommended that the flanges be wrapped to prevent foreign material from shorting out the flanges.
Type D Isolating Gaskets are available for RTJ flanges, the common material is phenolic and GRE.
