An expander flange, abbreviated as EXPF, is similar to a weld neck flange but with the hub expanding to a larger size (one or two sizes). If you have limited space or just need to connect to a larger pipe size, it provides a convenient way for equipment, pumps and valves. It can replace the use of a flange and reducer. Pressure ratings and dimensions are in accordance with ANSI/ASME B16.5. This flange has a raised face.
