Flange connections involve securing two pipes, fittings, or equipment to each side of a flange disk, inserting a flange gasket between them, and then fastening them together with bolts to complete the connection. Some fittings and equipment come with a built-in flange disk, 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, you may not see flange connections when the pipe diameter is small and the pressure is low. However, in boiler rooms or production sites, you'll find flanged pipes and equipment everywhere.
Flange connections can be categorized by their connection methods, including flat welding flanges, necked welding flanges, necked butt welding flanges, socket welding flanges, threaded flanges, flange covers, necked butt welding ring loose flanges, flat welding ring loose flanges, ring groove flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, blind flanges with bevel ends, and socket welding ring loose flanges, etc.
