Flange connections involve securing two pipes, fittings, or equipment to individual 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 flange discs already attached, which also fall under flange connections. Flange connections are an important method of pipe construction. They are convenient to use and can withstand high pressure. In industrial pipelines and residential settings, where pipe diameters are small and pressures are low, flange connections are not visible. However, in boiler rooms or production sites, you will find flange connections on pipes and equipment everywhere.
According to the connection method, flange types can be classified as: flat焊接plate flanges, socket焊接flanges, socket welding flanges, sleeve焊接flanges, threaded flanges, flange covers, socket welding ring loose flanges, flat ring loose flanges, ring groove flanges, and flange covers, large diameter flat flanges, large diameter long-neck flanges, blind flanges, socket welding ring loose flanges, etc.
