AboutFlange Insulation Gasket

Flange insulation gaskets are essential for preventing corrosion between different metals in flange connections. They act as a protective barrier, isolating the flange faces to avoid contact between incompatible materials. Two main types are full-face gaskets, covering the entire flange face, and ring gaskets, fitting within the bolt circle. These gaskets, typically made of non-conductive rubber or composite materials, provide effective corrosion protection in various industrial applications.

Goodrich Gasket provides comprehensive flange insulating gasket kits, which include the following components:

Phenolic laminate or neoprene-faced Phenolic laminate gasket [Type E & F only]: Placed between the flange sealing faces, these gaskets prevent direct contact between dissimilar metals.

Phenolic laminate bolt sleeves: These sleeves provide insulation for the bolts, further reducing the risk of galvanic corrosion.

Two insulating washers per bolt: These washers contribute to the electrical isolation of the flange components, helping to prevent the flow of electric charge.

Two plated mild steel washers per bolt: These washers provide structural support for the bolts. Stainless steel washers are available upon request for enhanced corrosion resistance.

Types of Flange Insulating Gasket

These three types cater to different flange designs, providing versatile solutions for effective insulation and corrosion protection in a variety of industrial settings.

Goodrich Gasket provides three standard types of Flange Insulating Gaskets designed to accommodate various flange configurations:

Goodrich Insulation Gasket Type “F” for Raised Face Flanges
Goodrich Insulation Gasket Type “E” for Full Face Flanges
Goodrich Insulation Gasket Type “D” for Ring Joint Gaskets

A self adhesive tape wrapped around the outside diameter of the flange provides complete electrical insulation and prevention of ingress of foreign matter. Phenolic material used in these insulation kits by Goodrich Gasket offer excellent insulation and corrosion resistance. Type E & F offered by Goodrich Gasket requires the bore of the gasket and the pipe to be equal to prevent any foreign matter from accumulating in the annular space between bore of the gasket and bore of the pipe, thus preventing bridging.
