What is flange ?

Flange is a part that connects between shaft and shaft and is used for connection between pipe ends; it is also useful for flanges on the inlet and outlet of equipment for connection between two equipment.

Flange connection refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures.

Pipe flanges refer to flanges used for piping in pipeline installations. There are holes on the flanges and bolts make the two flanges tightly connected. The flanges are sealed with gaskets.

The flange is divided into threaded connection (threaded connection) flange, welding flange and clamp flange. Flanges are used in pairs. Wire flanges can be used for low-pressure pipes, and welded flanges for pressures above 4 kg. A gasket is added between the two flanges and then tightened with bolts. The thickness of flanges with different pressures is different, and the bolts they use are also different.
