Industrial Flange
Flange, also known as flange plate or flaunching, is used to connect pipes on the end of the pipes. Two pipes, fittings or equipment are mounted with a flange apiece. A flange pad will be put between these two flanges, which are fastened together with bolts. There are also pipes and equipment which come with flanges originally, thus leading to easy connection. Pipes connected with flanges can be disassembled again.
Generally, flange can be easily installed and it can work under high pressure. Hence, it is extensively used for connection in pipeline construction. It is widely applied in many areas such as power generation plant, petroleum industry, natural gas system, chemical industry, shipbuilding industry, heating system, paper-making industry, metallurgy industry, etc.
Flange is often divided into many kinds, which include integral flange, welding neck flange, hubbed slip-on-welding flange, slip-on-welding plate flange, threaded flange, socket welding flange, blind flange, loose flange, orifice flange and spectacle flange, etc.
