Flange is an important mechanical connection, usually used to connect pipes to pipes, valves and other mechanical equipment. Its main functions include connection, sealing, ensuring safety and facilitating disassembly. Flanges fasten two or more components together through bolts, and are usually equipped with gaskets at the connections to achieve a good sealing effect. The design of the flange enables it to work under a variety of pressure conditions, and the appropriate flange type and specification can be selected according to different application scenarios.
There are many types of flanges. Depending on the connection method and structure, they can be divided into threaded flanges, butt welding flanges, flat welding flanges, socket welding flanges and other forms. Their applications are very wide, and flanges can be found in industrial pipes, domestic water systems, gas supplies, etc. The convenience and reliability of flange connections make them an indispensable part of industrial production and construction installations.
Flanges are made of various materials and can be metal, plastic or other composite materials, but the most common ones are carbon steel or stainless steel. Due to these characteristics of flange, it has important application value in pipeline engineering, petrochemical, electric power and many other industries.
