Flange connections involve securing two pipes, fittings, or equipment to separate flange discs first, then placing a flange gasket between the two discs and tightening them together with bolts to complete the connection. Some fittings and equipment come with their own flange discs and are also considered flange connections. Flange connections are an important 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-connected pipes and equipment everywhere.
According to the connection method, flange types can be categorized as: flat焊接plate flanges, socket焊接flanges, blind焊接flanges, slip焊接flanges, threaded flanges, flange covers, socket welding ring loose flanges, flat welding ring loose flanges, ring groove flanges, and flange covers, large diameter flat flanges, large diameter high neck flanges, winged blind flanges, and slip-on welding ring flanges, etc.
