Large flat welding flange

Large flat welding flange: easily obtained, create a simple, low cost, widely used; but less rigid, and therefore not be used in chemical process piping systems and a high degree of supply and demand, flammable, explosive and high vacuum degree requirements, extreme occasions. sealing surface hazards have flat and raised face.

Advantages of large welded flange is to create a simple, low cost, but a large amount of welding work, welding consumption, can not withstand high temperature, high pressure, repeated bending and temperature fluctuations role, generally used PN≤2.5MPa, at room temperature, t≤0 ℃ operating temperature of the pipeline.

Large plate welded flange (HG20593, GB / T9119, JB / T81): easily obtained, create a simple, low cost, widely used; but less rigid, and therefore not be used in supply and demand, flammable, explosive and higher chemical process piping systems and high vacuum degree requirements, extremely hazardous situations. sealing surface with a flat and raised face.

Industry standardization flange suitable HG20593-1997, GB GB / T9119-2000, machine standard JB / T81-94

The main dimensions and connecting dimensions reference plate flat welding flange (flange) is to connect two pipes, fittings or equipment, the first one on each flange fixed between two flanges, with flange gasket, bolted together to complete the connection. Some fittings and equipment already comes with flange, also belong to the flange connection. Flanged connections are important pipeline construction.

Flanged easy to use, able to withstand greater pressure.
