Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting. By applying pressure on the seal interface through bolt force, the “softer” metal of the gasket flows into the microfine structure of the harder flange material, and creating a very tight and efficient seal.

Raised Face RF The Raised Face flange is the most common type used in process plant applications, and is easily to identify. The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint.
