Flange, also known as flange or flange. Flange is a part of connecting shaft, which is used to connect pipe ends; It is also used for the flange on the inlet and outlet of equipment, and for the connection between two equipments, such as the flange of reducing pipe. Seal with flange gasket. Flanges are threaded (threaded), welded and clamped. Flanges are used in pairs. Threaded flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg. Add a gasket between the two flanges and fasten them with bolts.
