A carbon steel flat face flange is shortly referred to as FF. This weld neck flat face flange is a component which has been machined to be flat and, therefore does not have a ridge like structure as seen in either a raised face or ring type joint flange.  The flat surface of the socket weld flat face flange permits the gasket to have full contact with the entire surface of the mating material.  The design of the flat face has been created in such a manner for the sole purpose of eliminating the bending movement applied on the flange when the bolts have been torqued. When using either a cast iron or a fiberglass material flanges, this bending movement that occurs on it can easily break the flange.

It is possible albeit uncommon for flat face flange gaskets to be metallic gaskets. Usually gaskets for these flat face flanges are made from non-metallic materials consisting of EPDM or Viton.  It should go without saying that only a flat face gasket should be used on a ASME B16.5 Stainless Steel Flat Flange. In general, hydraulic flat face flange is used in low pressure as well as low temperature environments, for instance, either - water treatment or pump suction flanges. 


What is ASME B16.5 Stainless Steel Flat Flange?


Stainless Steel Flat Flange

The use of a Carbon Steel Flat Face Flange is usually seen when the piping or piping components tend to be brittle such as plastic, fiberglass or cast iron.  However, it should be noted that these Flat Face Flange ASME B16.5 Dimension are available in all different types of materials, including steel. As a flat flange gasket manufacturer in India, we produce these flat flanges in the form of in weld neck, socket weld, slip-on, or threaded.  Typically, flat flange gasket suppliers in India supply these flanges in ANSI 150 & 300 ratings.

ASME B16.5 Stainless Steel Flat Flanges has a gasket surface in the same plane as the bolting circle face. Applications using Flat Face Wn Flanges are frequently those in which the mating flanges or flangesd fitting is made from a casting. Threaded Flat Face Flanges are used when the counter-flanges are flat face. 150# Flat Face Slip On Flange condition occurs mainly on connection to Cast Iron equipment, specialties, and valves.
