Flange Insulation Gasket Kits
Insulating sets are essentially used for pipeline flange corrosion protection, where a seal is required between dissimilar flange materials. The use of dissimilar metallic flanges with a conductive gasket material accompanied with a suitable electrolyte may set up a galvanic cell which will corrode the anodic metal. Insulating sets are also used to electrically isolate flange joints, preventing the flow of electrostatic charge along pipelines.
There are three standard Types of insulating sets available to suit raised face, flat face, and ring grooved flanges, as illustrated below.
FLIPS India Engineering Insulation Gaskets For Type "F" Raised Face Flanges
In this type, the central gasket is designed to be located inside the flange bolt circle and sits fully on the raised face porting of the flange. This type of gaskets will be supplied in all the materials shown in Table
FLIPS India Engineering Insulation Gaskets For Type "E" For Full Face Flanges
In this type, the central gasket has its outside diameter as equal to that of flange outside diameter and precision cut bolt holes. This design helps easy alignment of the gaskets during installation. Type "E" gaskets are available in Neoprene faced reinforced phenolic material or other materials in Table.
FLIPS India Engineering Insulation Gaskets For Type "D" For Ring Joint Gaskets
In this type the gaskets available in fabric reinforced Phenolic. Available in basic "Oval & Octagonal" type. This type has the contact faces with oval shape. It provides a high reliability seal. These gaskets comply with ASME B - 16.20.
