Flat Flanges

The Flat Face (FF) flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting. Flat face flanges are never to be bolted to a raised face flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.

Flat Face Flange – This type of flange face is for all applications where “Cast Iron” (orother brittle material) is used to make equipment and valves. Cast  Iron is brittle and iscommonly used only in  low temperature, low pressure applications. The flat surfaceallows for full contact across the whole face of the two flanges. Only Full  Face Gasketsare to be used  for “Flat Face” flanges. This  ensures full and equal contact between thetwo mating flanges.
