Flange connections involve securing two pipes, fittings, or equipment to separate flange plates first, then inserting a flange gasket between the two plates and fastening them together with bolts, thereby completing the connection. Some fittings and equipment come with built-in flange plates and are also considered flange connections. Flange connections are an important 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 pipes and equipment everywhere.
According to the connection method, flange types can be classified as: flat焊接flanges, neck welding flanges, socket welding flanges, plug welding flanges, threaded flanges, flange covers, neck socket welding ring loose flanges, flat socket welding ring loose flanges, ring groove flanges and flange covers, large diameter flat flanges, large diameter high-neck flanges, blind flanges with diagonal slots, socket welding ring loose flanges, etc.
