Flange connections involve securing two pipes, fittings, or equipment to separate flange plates first, then joining the two flange plates together with a flange gasket and bolts to complete the connection. Some fittings and equipment come with a built-in flange plate, which also falls under flange connections. Flange connections are an essential method in pipeline construction. They are convenient to use and can withstand high pressure. In industrial pipelines and residential settings, where pipe diameters are small and the pressure is low, flange connections are not visible. However, in boiler rooms or production sites, flange connections are everywhere, both on pipes and equipment.
Flanged connections can be categorized by type of connection as follows: flat焊接法兰,焊接颈法兰,焊接颈对焊法兰,承插焊法兰,螺纹法兰,法兰盖,焊接颈对焊环松套法兰,平焊环松套法兰,环槽面法兰 and法兰盖, large diameter flat flange, large diameter high-neck flange, blind flanges, welding ring loose fit flange, etc.
