A flange is a transliteration of the English word 'FLANGE', also known as a flange plate or rim. A flange is a part that connects pipes, valves, pumps, and other equipment to form a piping system. Flanges are sealed with gaskets, and they have holes through which bolts connect the two flanges tightly. Before the invention of flanges, rivets were used for connecting and fixing structures. The introduction of flanges has made the construction and processing of crude oil simpler. A flange is an item or part with a rim, which can be separate and may have holes or not. Flanges are often used for edge positioning. Stainless steel flange connections are the primary connection structure in pipeline construction. Flange connections involve fixing two pipes, fittings, or devices to a flange plate, then adding a flange gasket between the two flange plates and tightening them together with bolts to achieve the connection. Some fittings and devices already come with flange plates, which also belong to flange connections.
