Flange is called flange for short, which is just a general term. It usually refers to opening several fixing holes around a disk-shaped metal body for connecting other things. This thing is widely used in machinery, so it looks strange. As long as it is called flange, its name comes from English flange.
Flange is also called flange or flange. The parts that connect pipes to each other are connected to the pipe end. There are holes on the flange, and the bolts connect the two flanges tightly. The flanges are sealed with gaskets. Flange is a kind of disk-shaped parts, which is the most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, flange is mainly used for pipeline connection. At the end where two pipes need to be connected, a flange shall be installed respectively. Threaded flanges can be used for low-pressure pipes, and welded flanges can be used for pressure above 4kg. A sealing gasket shall be added between the two flanges and then fastened with bolts.
Flanges with different pressures have different thicknesses and use different bolts.
When pumps and valves are connected with pipes, parts of these equipment are also made into corresponding flange shapes, also known as flange connection.
All connecting parts that are bolted and closed around two planes are generally called “flange”, such as the connection of ventilation pipe. This kind of parts can be called “flange parts”.
Threaded flange is a kind of flange. The threaded flange connection structure is an assembly, which is composed of a pair of flanges, several bolts, nuts and a gasket.
