Flange connections involve securing two pipes, fittings, or equipment to each side of a flange, then fitting a flange gasket between them and tightening them together with bolts, thus completing the connection. Some fittings and equipment come with a built-in flange, which also falls under flange connections. Flange connections are a crucial method in pipeline construction. They are convenient to use and can withstand high pressure. In industrial pipelines and residential settings, you might not see flange connections when the pipe diameter is small and the pressure is low. However, in boiler rooms or production sites, flange connections are ubiquitous on pipes and equipment.
Flanged connections can be categorized by type of connection as: flat焊接flanges, welding neck flanges, socket welding flanges, slip-on flanges, threaded flanges, blind flanges, loose fit welding neck ring flanges, loose fit flat ring flanges, ring groove flanges, and blind flanges, large diameter flat flanges, large diameter welding neck flanges, L-shaped blank flanges, and loose fit welding neck flanges, etc.
