Flange connection is the two pipes, fittings or equipment. First of all, fixed on a flange, and then between the two flanges and flange gasket. Finally, a detachable joint, which is made up of two flanges by means of bolts.

Flange connection use

Flange connection is mainly used for cast iron pipe, lined rubber hose, non ferrous metal pipe and flange valve connection, the process equipment and flange connection are also using flange connection.

Flange connection is characterized by easy disassembly, high strength, good sealing performance. When the requirements of the two flange mounting flange sealing surface can not be damaged, keep parallel flange, and to clean up. Flange gaskets used in accordance with the design requirements.

Flange connection

Flange threaded connections (wire connection) flanges and welded flanges. Low pressure and small diameter wire connecting flange, high pressure and low pressure large diameter are used to weld flange, different pressure flange thickness and bolt diameter and quantity is different.

According to the different levels of pressure, flange pad also has a variety of materials, from the low pressure and high pressure asbestos gasket asbestos gasket, PTFE pad to the metal pads are.

Flange connection is easy to use, can withstand greater pressure.

Flange connections are widely used in industrial pipelines. In the home, the pipe diameter is small, and is low pressure, can not see the flange connection. If in a boiler room or production site, the flange is connected to the pipe and equipment.
