Flange connections involve securing two pipes, fittings, or equipment to separate flange plates first, then inserting a flange gasket between them and fastening them together with bolts, thus completing the connection. Some fittings and equipment come with built-in flange plates, which also fall 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.
According to the connection method, flange types can be categorized as: flat welding flange, socket welding flange, blind flange, threaded flange, bolted flange, flange cover, socket welding ring loose flange, flat welding ring loose flange, ring groove flange and flange cover, large diameter flat flange, large diameter long neck flange, winged blind flange, socket welding ring loose flange, etc.
