A flange is a component used to connect shafts to each other or to connect pipe ends; there are also flanges used at equipment inlets and outlets for connecting two devices, such as reducer flanges. A flange connection or flange joint refers to a removable connection formed by the combination of a flange, a gasket, and bolts, also known as a flange boss or rim.
Flange Usage: Flanges are always used in pairs. For low-pressure pipelines, threaded flanges can be used, while for pressures above 4 kg, welding flanges are required. Place a sealing gasket between the two flange disks and then secure them with bolts. Flanges of different pressures have varying thicknesses and require different bolts.
