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.
First, to measure the standard pipe flanges, measure the outer diameter of the flange (O.D.). It can be achieved by measuring from the outer edge of the flange to the opposite outer edge and then measuring the flange's inner diameter from these two outer reference points.
