[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected together as a sealing structure. Pipe flanges refer to flanges used for piping in pipeline installations; on equipment, they refer to the inlet and outlet flanges of the equipment. Flanges have holes, and bolts are used to tightly connect two flanges. A gasket is used for sealing between flanges. Flanges are classified into threaded flanges, welded flanges, and clamp flanges. Flanges are always used in pairs; threaded flanges can be used for low-pressure pipelines, while welded flanges are used for pressures above four kilograms. A gasket is placed between two flange plates, and then they are tightened with bolts. Flanges of different pressures have different thicknesses, and the bolts used for them are also different.
