Flange connections involve securing two pipes, fittings, or equipment to separate flange discs first, then inserting a flange gasket between the two discs and fastening them together 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, flange connections are abundant on pipelines and equipment.
Flange connections can be categorized by type of connection as: flat焊接flanges, socket焊接flanges, blind焊接flanges, lug焊接flanges, threaded flanges, flange covers, socket焊接ring type loose flanges, flat焊接ring type loose flanges, ring groove flanges and flange covers, large diameter flat flanges, large diameter high-neck flanges, L-shaped blind flanges, welding ring loose flanges, etc.
