A flange is a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flange joints are made by bolting together with two flanges with a gasket between them to provide a seal.
The most used flange types in Petro and chemical industry are:
Class: 150# - 2500#
Standard: ASME B16.5, ASME B16.47, B16.36, API6A
