Flange connections involve fixing two pipes, fittings, or equipment to separate flange plates first, then adding a flange gasket between the two flange plates and securing them together with bolts to complete the connection. Some fittings and equipment come with built-in flange plates, which also fall under flange connections. Flange connections are an essential 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, flange-connected pipes and equipment are everywhere.
According to the type of connection, flange connections can be categorized as: flat焊接flanges, socket焊接flanges, blind焊接flanges, lug焊接flanges, threaded flanges, flange covers, ring-type loose flanges with neck welding, flat ring loose flanges, ring groove flanges and flange covers, large diameter flat flanges, large diameter high-neck flanges, L-shaped blank flanges, loose socket welding ring flanges, etc.
