Flange connections involve securing two pipes, fittings, or equipment to separate flange discs first, then joining the two flange discs together with a flange gasket in between, and finally tightening them with bolts to complete the connection. Some fittings and equipment come with a flange disc already attached, 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, you'll find flange connections on pipes and equipment everywhere.
According to the type of connection, flange connections can be classified into: flat焊接 flanges, socket焊接 flanges, welding neck flanges, lug焊接 flanges, threaded flanges, flange covers, welding neck loose fit flanges with collar, flat loose fit flanges with collar, ring groove flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, L-shaped blank flanges, and loose fit welding neck flanges, etc.
