Flange:
Flange, also known as flange or flange. Flange is a part connecting pipes, which is used to connect pipe ends. It is also very useful for the flange on the inlet and outlet of equipment, which is used to connect two devices, such as the flange of reducer. Flange connection or flange joint refers to the detachable connection in which flanges, gaskets and bolts are connected with each other to form a set of combined sealing structure. Pipeline flange refers to the flange used for pipeline in pipeline equipment, and refers to the import and export flange of equipment when used on equipment. There are holes in the flanges, and bolts make the two flanges closely connected. The flange is sealed with a gasket. Flanges are divided into threaded flanges, welded flanges and clamping flanges. Flanges are used in pairs. Threaded connecting flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above four kilograms. Add a gasket between the two flanges and fasten it with bolts. Flanges with different pressures have different thicknesses, so the bolts used are different. When pumps and valves are connected to pipelines, the parts of these devices are also made into corresponding flange shapes, which is also called flange connection. All connecting parts that are bolted around two planes and closed at the same time are generally called "flanges", such as the connection of ventilation pipes, which 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, so it is not good to call the water pump a "flange part". Smaller parts, such as valves, can be called "flange parts"
Reducer flange is used for the connection between motor and reducer, and the connection between reducer and other equipment.
