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.
Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
