Flange connections involve securing two pipes, fittings, or equipment to separate flange discs first, then inserting a flange gasket between them 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 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 the pressure is low, flange connections are not visible. However, in boiler rooms or production sites, you'll find flange connections on pipelines and equipment everywhere.
According to the connection method, flange types can be categorized as: flat焊接flanges, neck welding flanges, neck butt welding flanges, socket welding flanges, threaded flanges, flange covers, neck butt welding ring loose flanges, flat welding ring loose flanges, ring groove flanges and covers, large diameter flat flanges, large diameter high neck flanges, winged blind flanges, and socket welding ring loose flanges, etc.
