Applications

that require the use of flat face flanges are frequently those systems where the mating flanges or flanged fitting is produced from a casting. The ANSI B16.5 standard is limited to those flanges and their corresponding fittings which are generally made from cast or forged materials.

An ASME B16.5 Flat Face Flange has a gasket surface in the same plane as the bolting circle face.

The ANSI B16.5 Flat Face Flange Standards also includes requirements as well as recommendations regarding flanges gaskets, flanges bolting, and flanges joints.

Essential points covered by the standard include pressure-temperature ratings, tolerances, marking, materials, dimensions, testing, and the various methods of designating openings for Carbon Steel Flat Face Flange and flanged fittings. While the pressure rating of these flanges is in the following class designations i.e. 150, 300, 400, 600, 900, 1500, and 2500, a Stainless Steel Flat Flange is produced by manufacturers in sizes NPS 1/2 through NPS 24.
