Plate flat welding flange convenient materials, simple manufacturing, low cost, widely used; But the rigidity is poor, so it can not be used for supply and demand, flammable, explosive and high vacuum requirements of chemical process piping system and height, extremely hazardous occasions. The sealing surface type has a plane and a protruding surface. Plate flanges are widely used in pipeline systems in chemical, petroleum, natural gas, pharmaceutical, food and other industries.
Flange connection is the two pipes, pipe fittings or equipment, respectively fixed on a flange plate, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipeline. In the home, the pipe diameter is small, and is low pressure, not visible flange connection. If you're in a boiler room or a production site, there are flanged pipes and equipment everywhere.
