Flange gasket

A flange gasket is a type of gasket made to fit between two sections of pipe that are flared to provide higher surface area.

Steel pipe flange gaskets are used to create seal between two flange faces. The flange face acts at the seal seat and the flange gasket compresses between two flanges, with the bolt compression, to fill all irregularities in the flange face and create a seal.

The gasket is selected based on the operating condition such as pressure, temperature and chemical exposure. Gaskets are available in following three types;

Full Face Gasket: covers the full face of the flange. Generally used on flat face flanges

Flat ring Gasket: covers only the sealing surface or the raised face of the flange.

Metallic Ring Gakset: designed to be fitted in RTJ Flanges.
