  Flange is a part that connects between shaft and shaft and is used for connection between pipe ends. It is also used as flange on the inlet and outlet of equipment. Flange is also called flange flange or flange. Used for connection between two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures.

  There are holes on the flanges and bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange flange refers to the flange used for piping in the pipeline installation, and refers to the inlet and outlet flanges of the equipment when used on the equipment. Split threaded connection flange, welding flange and clamp flange. Flanges are used in pairs, low-pressure pipes can use wire flanges, and welded flanges for pressures above 4 kg. A gasket is added between the two flanges and then tightened with bolts.

  The thickness of flanges with different pressures is different, and the bolts they use are also different. When water pumps and valves are connected with pipelines, parts of these equipments are also made into corresponding flange shapes, also called flange connections. All connecting parts that are connected by bolts and closed at the same time around two planes are generally called "flanges", such as the connection of ventilation pipes. This type of part can be weighed, but this connection is only a part of the equipment, such as a flange. The connection with the water pump makes it difficult to call the water pump "flange parts". Smaller ones, such as valves, can be called "flange parts".
