Flange is the interconnecting part of pipe and pipe, which is used for the connection between pipe ends. Flanges are also used at the inlet and outlet of the equipment for the connection between two devices (e.g. reducer flanges). Flange connection or flange connection refers to a removable connection in which flanges, gaskets and bolts are connected to each other to form a group of sealing structures. Pipe flange refers to the flange used in the pipeline for pipeline use, and refers to the inlet and outlet flanges of equipment in equipment. There are holes in the flange, and two bolts are tightly connected to the flange. Between flange gasket seals. Flange threaded connection (threaded connection) flange, welding flange and clamping flange.
Flanges are used in pairs, low-pressure pipes can be used for connecting flanges, and pressure welding flanges of more than 4kg. Use a gasket between the two flanges and then connect them with bolts. Different thickness of flange pressure, they use different bolts. Pumps and valves, as well as pipe connections, these equipment, local equipment, are also made into corresponding flange shapes, also known as flange connections. Among them, the parts that are bolted around the two planes and closed at the same time are generally called “flanges”. For example, ventilation pipe connection, this type of parts can be called “flange parts”. However, this connection is only a part of the equipment, such as the connection between the flange and the pump, so it is called the “flange part” of the pump. Relatively small, such as valves, can be called “flanged components”.
