We are a government approved largest Manufacturer, Supplier and Exporter of ASME 16.5 Flat Flanges. The Flat Face 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, Our flat flanges sit flat on the ground and have a neck. The flat face (full face) flange has a gasket surface in the same plane as the bolting circle face.
