Flange connections involve fixing two pipes, fittings, or equipment to separate flange plates first, then placing a flange gasket between them and securing them together with bolts, completing the connection. Some fittings and equipment come with a flange plate already attached, which also falls under flange connections. Flange connections are an essential method for pipeline construction. They are convenient to use and can withstand high pressure. In industrial pipelines and residential settings, where pipe diameters are small and pressure is low, flange connections are not visible. However, in boiler rooms or production sites, you'll find flange-connected pipes and equipment everywhere.
According to the type of connection, flange connections can be categorized as: flat welding flanges, socket welding flanges, blind flanges, threaded flanges, flange covers, loose fitting socket welding flanges, loose fitting flat welding flanges, ring groove flanges, large diameter flat flanges, large diameter long neck flanges, L-shaped blank flanges, and socket welding ring loose flanges, etc.
