Flange, also known as flange flange or flange. A flange is a component that connects shafts and is used for connecting pipe ends; Also useful is a flange on the inlet and outlet of the equipment, used for connecting between two devices, such as a gearbox flange. Flange connection or flange joint refers to a detachable connection consisting of flanges, gaskets, and bolts connected to each other as a combination sealing structure. Pipeline flange refers to the flange used for piping in pipeline devices, and when used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts make the two flanges tightly connected. Seal the flanges with gaskets. The flange is divided into threaded connection (threaded connection) flange, welding flange, and clamp flange. Flanges are used in pairs, and threaded flanges can be used for low-pressure pipelines. Welding flanges can be used for pressures of over four kilograms. Add a sealing gasket between the two flange plates and tighten them with bolts. The thickness of flanges under different pressures varies, and the bolts used are also different. When connecting water pumps and valves to pipelines, the local parts of these equipment are also made into corresponding flange shapes, also known as flange connections. Any connecting part that is closed and bolted around two planes is generally referred to as a "flange", such as the connection of a ventilation duct. This type of part can be referred to as a "flange type part". But this connection is only a partial part of the equipment, such as the connection between the flange and the water pump, so it is not easy to call the water pump a "flange type part". Smaller parts such as valves can be called "flange parts".

The reducer flange is used for the connection between the motor and the reducer, as well as the connection between the reducer and other equipment.
