Groove pipe flange is also called flange flange plate or flange. Flange is the part connecting the pipe to the pipe, which is used for the connection between the pipe ends; it is also used for the connection between the two equipment, such as the reducer flange.
Flange connection or flange joint refers to the detachable connection with flange, gasket and bolt as a group of combined sealing structure. Pipeline flange refers to the flange used for piping in the pipeline device, and for equipment, it refers to the inlet and outlet flange of the equipment.
There are eyebolts on the flange of grooved pipe fittings to make the two flanges tightly connected. The flange is sealed with gasket. Flange is divided into threaded connection (threaded connection) flange, welding flange and clamp flange. Flange is used in pairs, low-pressure pipeline can use screw flange, more than four kilograms of pressure use welding flange. Add gasket between two flange plates, and then fasten them with bolts. The flange thickness of different pressure is different, and they use different bolts.
When the water pump and valve are connected with the pipeline, the parts of these equipment are also made into corresponding flange shape, also known as flange connection. All the connecting parts that are closed at the same time with bolt connection around the two planes are generally called "groove pipe flange", such as the connection of ventilation pipe, this kind of parts can be called "flange parts". But this kind of connection is only a 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 "flange parts". Smaller ones, such as valves, can be called "flange parts".
