Carbon steel Flat flanges

A flat steel flange is cited as a flange that is machined flat and does not have a ridge like a raised face or ring type joint flange. The flat surface of loose flat flange allows for the gasket to have full contact with the entire mating surface. The purpose of the flat face flange slip on is to eliminate the bending moment put on the flange when the bolts are torqued. Using cast iron and fiberglass flanges.

It is possible but uncommon for flat face threaded flange gaskets to be metallic gaskets. Typically flat face slip on flange gaskets are made from non-metallic materials such as EPDM or Viton. It should go without saying that only flat face gaskets should be used on flat face flanges.

In general, flat neck flanges are used in low pressure and temperature environments such as water treatment or pump suction flanges. Flat face carbon steel flange are usually common when the piping or piping components are brittle such as plastic, fiberglass or cast iron. However, it should be noted that flat face lap joint flange come in all different types of materials, including steel.

Aside from the fact that some codes specify that mating surfaces should both be flat (ASME B31.1), it is good design practice to not mix flange facings whenever possible. The reasoning for this is that the flat face ring joint flange may not be designed to withstand the forces put on the outer most edge when the bolts and nuts are tightened.

The dimensions for a stainless steel flat face flange are the same as the dimensions for a raised face flange but without the raised face. Flat face weld neck flange are often found 150# and 300# ratings.
