Flange connections involve securing two pipes, fittings, or equipment to each side of a flange disk, inserting a flange gasket between them, and then tightening them together with bolts, thus completing 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 connections on pipes and equipment everywhere.

Flanged connections can be categorized by type of connection as: flat welding flange, neck welding flange, socket welding flange, lug welding flange, threaded flange, flange cover, neck socket welding ring loose flange, flat socket welding ring loose flange, ring groove flange and flange cover, large diameter flat flange, large diameter high neck flange, L-shaped blind flange, socket welding ring loose flange, etc.
