What is flange?

Flange is also called flange or flange. Flanges are parts that connect pipes to each other and are connected to pipe ends. There are holes on the flanges, and bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange is divided into threaded connection (wire connection) flange and welding flange. Flange is a disc-shaped part, which is the most common in pipeline engineering, and flanges are used in pairs. In pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, various flanges are installed. Wire flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg. Add a sealing point between the two flanges and fasten them with bolts. Different pressure flanges have different thicknesses and use different bolts. When pumps and valves are connected to pipelines, the parts of these equipment are also made into corresponding flange shapes, also known as flange connections. Any connecting parts that are bolted at the periphery of two planes and closed at the same time are generally called "flanges", such as the connection of ventilation ducts, this type of parts can be called "flange parts". But this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not easy to call the water pump "flange parts". Smaller ones, such as valves, can be called "flange parts"
