Flange connections involve securing two pipes, fittings, or equipment to each side of a flange disk first, then joining the two flanges together with a flange gasket and螺栓. This completes the connection. Some fittings and equipment come with a flange disk pre-installed 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 the pipe diameter is small and the pressure is low, flange connections are not visible. However, in boiler rooms or production sites, you will find flange connections on pipes and equipment everywhere.

The types of flange connections, categorized by their connection methods, include: flat焊接plate flanges, socket焊接flanges, welding neck flanges, slip-on flanges, threaded flanges, flange covers, welding neck ring-type slip-on flanges, flat ring-type slip-on flanges, ring groove flanges and flange covers, large diameter flat flanges, large diameter welding neck flanges, winged blind flanges, and slip-on welding neck flanges, etc.
