Description
SW flanges are produced and used according to certain principles to ensure that they can be used in the correct way and provide good use value.
It is suitable for pipelines with large pressure or temperature fluctuation or high temperature and high pressure pipelines.
SW flange refers to the flange with the pipe end inserted into the flange ring ladder and welded at the pipe end and outside.
The flange has good rigidity, small welding deformation and good sealing performance. It can be used for the occasion with pressure of 1.0 ~ 10.0MPa.

Characteristic
SW flange is not easy to deform, has good sealing performance and is widely used. The nominal pressure PN is about 16MPa.
The butt size of the flange varies with the nominal pressure, and it is also used to transport expensive, flammable and explosive media.
Application
SW flange can be widely used in petrochemical, power, chemical, shipbuilding, pharmaceutical, paper and other national projects.
