Flange connections involve fixing two pipes, fittings, or equipment individually to flange disks, then securing them together with a flange gasket and bolts, thus completing the connection. Some fittings and equipment come with flange disks, which also fall under flange connections. Flange connections are a crucial 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 pressures are 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 classified as: flat焊接plate flange, socket welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, socket welding ring loose flange with neck, flat welding ring loose flange, ring groove face flange and cover, large diameter flat flange, large diameter high neck flange, L-shaped blank flange, and butt welding ring loose flange, etc.
