It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection consisting of flange, gasket and bolts connected to each other as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline installations. When used on equipment, it refers to the inlet and outlet flanges of the equipment. During the production process of the flange, in order to increase the use effect and quality of the flange, it is often necessary to polish and grind the flange to remove burrs and rust on the flange surface.
