Flange connections involve securing two pipes, fittings, or equipment to each side of a flange disk, then fitting a flange gasket between the two disks and tightening them together with bolts to complete the connection. Some fittings and equipment come with a flange disk already attached, which also falls under flange connections. Flange connections are a crucial method in pipeline construction. They are convenient to use and can withstand significant 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 will find flange-connected pipes and equipment everywhere.
Flange connections can be categorized by their connection methods, including: flat焊接flanges, socket焊接flanges, blind焊接flanges, lug焊接flanges, threaded flanges, flange covers, loose-fit ring-type blind焊接flanges, flat ring-type loose-fit flanges, ring groove flanges, and covers, large diameter flat flanges, large diameter high-neck flanges, L-shaped blind flanges, and loose-fit ring-type welding flanges, etc.
