Flange

Flange , also called flange flange disk or flange. Flange is a pipe and pipe interconnecting parts, for the connection between the pipe end; also used in the equipment import and export flange, for the connection between the two devices, such as reducer flange. Flange connection or flange joint, refers to the flange, gasket and bolt three interconnected as a group of combined sealing structure of the detachable connection. Piping flange refers to the piping device in the piping flange, used in equipment refers to the import and export of equipment flange. There are holes on the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flanges are divided into threaded connection (screw connection) flanges, welding flanges and clamping flanges. Flanges are used in pairs, low-pressure pipelines can be used silk flange, four kilograms of pressure above the use of welded flanges. A gasket is added between the two flanges, which are then bolted together. Different pressure flange thickness is different, they use different bolts. Water pumps and valves, in connection with the pipeline, the localization of these devices and equipment, but also made of the corresponding flange shape, also known as flange connection. Where the two planes around the use of bolts to connect the connection parts closed at the same time, generally known as the "flange", such as ventilation pipe connection, this type of parts can be called "flange parts". But this connection is only a local equipment, such as flange and pump connection, it is not good to call the pump "flange parts". Comparatively small, such as valves, etc., can be called "flange parts".Reducer flange, used for motor and reducer connection, as well as reducer and other equipment between the connection.
