Flange connections involve fixing two pipes, fittings, or equipment to each side of a flange disk, then inserting a flange gasket between the two flanges and securing them together with bolts, thereby completing the connection. Some fittings and equipment come with a built-in flange, 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 the pipe diameter is 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.
Connection types of flanges can be classified according to the connection method: flat welding flange, socket welding flange, slip-on flange, threaded flange, blind flange, loose ring flange, flat ring loose flange, bevel groove flange, large diameter flat flange, large diameter high neck flange, winged blind flange, and slip-on ring flange, etc.
