Flange connections involve securing two pipes, fittings, or equipment to separate flange plates first, then placing a flange gasket between the two plates and fastening them together with 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 the pipeline diameter is small and the pressure is low, flange connections are not visible. However, in boiler rooms or production sites, you'll find flange connections on 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 fit socket welding flanges with neck, flat welding loose fit flanges, ring groove flanges, and flange covers, large diameter flat flanges, large diameter high-neck flanges, L-shaped blind flanges, socket welding loose fit flanges, etc.
