Overview of Flat Face Flanges

Flat Face Flanges, also known as FF Flanges or Flat Face Type Flanges, are a type of flange where the face is completely flat and designed to sit flush against the mating surface of the pipe or equipment. Unlike raised face flanges, Flat Face Flanges distribute pressure evenly and are ideal for low-pressure systems or applications where flanged equipment has a flat face.
