Provides complete protection for both flange faces
Comes with the same outside diameter of the flanges. Hence, the foreign material collection between the flange faces is prevented
Ensures complete cathodic isolation
The E gaskets are available in Plain faced Phenolic, Neoprene faced Phenolic and high temperature material like G-10
Type F (Raised Face Type Gasket)
Designed to fit only onto the raised face surface of the flanges
Outside diameter of the gasket is slightly lesser than the inside diameter of bolt circle
For best results, the flanges must be wrapped with Flange Band Protectors. So foreign materials are prevented from collecting and creating a bridge, thus shorting out the isolation
Available in same material as Type E
Type D (RTJ Type Gaskets)
Designed to fit into the ring groove of RTJ flanges
Available in Phenolic and G10 material types
G10 / G11 with viton / Spring energised Gaskets
We use a machined glass-reinforced epoxy (GRE) resin with an O-ring or spring energised seal to produce this insulation set
These gaskets can be used for flange ratings from class 150 to 600
Improvises compressive strength over conventional insulation sets
Provides greater resistance to over compression and cracking
Metal Core with G10 / G11 Gaskets
Highly reliable for both insulating and general sealing purposes in critical services
These gaskets have a proven track record of integrity in aggressive sealing situations
Suitable in all services up to and including ANSI 2500# and API 15,000# classes
Metal Core with G10/G11 gaskets consists of a PTFE (Teflon) spring-energized face seal, or an elastomeric o-ring
Accommodated in an insulating laminate that is permanently bonded to a high-strength metal gasket core
