Flange, also called flange flange disc or flange. Fl ange is a shaft and shaft connected parts, used for the connection between the pipe ends; Also usef≈ul in the equipment inlet and outlet flange, used for the connection between two equi'pment, such as reducer flange. Flange connection or flange joint, refeπrs to the flange, gasket and bolts are connected to each other as a group of assembly sea¶ling structure of the detachable connection. Pipeline flanges refer to the fl"anges of piping devices and the inlet and outlet flanges of equipment when  used in equipment. There are holes in the flanges and bolts ho✔ld the two flanges together. Use gasket to seal between flanges. Flange←s are divided into thread connection (thread connection)  flange, welding flange and clamping flange. Flanges are used in pairs, wire connection fl♠anges can be used for low pressure pipes, welding flanges can be used for more ★than four kilograms of pressure. Add sealing gasket between two flanges, and φthen tighten with bolt. Flanges of different pressur×es have different thicknesses and use different bolts. Water pump and valve, in connection wi$th the pipeline, the local equipment, also made into the correspon​ding flange shape, also known as the flange connection. Usually i§n the two plane surrounding the use of bolt connecti★on at the same time closed connecting parts, generally kno'wn as the "flange", such as ventilation pipe connection, this ki×nd 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 pump, it is not good" to call the pump "flange parts". Comparatively small, such as valves, can be called "flange parts"≠
