Flange connections involve securing two pipes, fittings, or equipment to separate flange discs first, then adding a flange gasket between the two flange discs and fastening them together with bolts to complete the connection. Some fittings and equipment come with their own flange discs and are also considered flange connections. Flange connections are an important method of pipe 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 connections are普遍 found on pipes and equipment.

Flanged connections can be categorized by their connection methods, including: flat焊接flanges, socket焊接flanges, blind焊接flanges, threaded flanges, flange covers, loose-tightening ring flanges with neck and blind焊接, flat ring loose-tightening flanges, ring groove flanges and flange covers, large diameter flat flanges, large diameter high-neck flanges, winged blind flanges, loose-tightening ring flanges for blind焊接, etc.
