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.

Flanges are all used in pairs, wire flanges can be used for low-pressure pipes and welded flanges for pressures above 4 kg. A gasket is added between the two flanges and then tightened with bolts. The thickness of flanges for different pressures is different, and the bolts they use are also different. When water pumps and valves are connected with pipelines, parts of this equipment are also made into corresponding flange shapes, also known as flange connections. All connecting parts that are connected by bolts on the periphery of two planes and are closed at the same time are generally called flanges, such as the connection of ventilation pipes. This type of part can be called flange parts.
