Flat Face Flange

Flat faced flange is a flange that is machined flat and does not have a ridge like a raised face or ring type joint flange. The flat surface allows for the gasket to have full contact with the entire mating surface. The purpose of the flat face is to eliminate the bending moment put on the flange when the bolts are torqued. When using cast iron or fiberglass flanges, this bending moment can easily break the flange.In general, flat faced flanges are used in low pressure and temperature environments such as water treatment or pump suction flanges. Flat face flanges are usually common when the piping or piping components are brittle such as plastic, fiberglass or cast iron. However, it should be noted that these flanges come in all different types of materials, including steel.
