YUHONG GROUP - Introduction of flange

Flange is a shaft and shaft interconnection parts, used for the connection between the end of the pipe; also used in the import and export of equipment on the flange, used 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 flanges, welded flanges and clamping flanges. Flanges are used in pairs, low-pressure pipelines can use silk-joined flanges, more than four kilograms of pressure to use welded flanges. A gasket is added between the two flanges and then bolted tight. Flanges of different pressures have different thicknesses and they use different bolts. Water pumps and valves, in connection with the pipeline, the localisation of these devices and equipment, also made into the corresponding flange shape, also known as flange connection. Where in 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 the connection of ventilation ducts, this type of parts can be called ‘flange parts’. But this connection is only a local device, 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’.
