Flange is an important connection piece for pipelines and mechanical equipment, with various types and application fields. The following are the main classifications of flanges and their uses:
Classification:
According to the connection method: flanges can be divided into threaded connection (threaded connection) flange, welding flange and clamping flange.
According to the structure of the flange: it can be divided into flat flange, flange flange, lapel flange and socket flange.
According to national standards: Flanges can be divided into German standard flanges, American standard flanges, Japanese standard flanges and national standard flanges according to different national standards.
According to usage: Flanges are widely used in various industries, such as petrochemical, electric power, water conservancy, shipbuilding, construction, etc.
use:
Pipe connections: Flanges are used to connect pipe ends, ensuring the efficient operation of the pipe system.
Equipment connection: Flanges can also be used to connect equipment, such as the connection between motors and reducers, or the connections between multiple devices.
Specific applications: Flanges are also used in special occasions, such as marine flanges for ships and construction flanges for the construction industry.
Flange connection is a combined sealing structure composed of flanges, gaskets and bolts. The two flanges are closely connected through bolts, and a gasket is used for sealing to prevent leakage. Flanges of different pressure levels have different thicknesses and usage conditions, so bolts of corresponding thickness will be selected to ensure the safety and reliability of the connection.
