Who knows, the difference between plate flange and hubbed flange in the application.
In the words of the most popular bar, welding plate flange is inserted into the pipe flange to weld. There is a small tail behind and hubbed flange means, the outer diameter is relatively small tail pipe diameter is the same. That's what it means to put this little tail against the tube and weld it together.
Welding plate flange for general medium.Hubbed flange suitable for the inflammable and explosive, corrosive, toxic high placesThe sealing surface of flange plate are raised face (RF), hubbed flange sealing surface can be used from surface, convex surface, tongue and groove face.The two structures are different, the sealing effect is not the same, the strength is not the same.
Hubbed flange is imported from abroad, used for gas valves, gas pipelines etc.. Because of a short neck, flange stiffness can be improved and bearing capacity improved.
