Flanges for piping or equipment connected to pressure higher than 10MPa for high-pressure flange. So, what are the characteristics of high pressure flange? Below high-pressure flange factory staff to introduce to you.
1, bending performance: A large number of tests show that the flange in the withstand of large bending load, will not leak or loose, the actual test: DN15 specifications of high-pressure flange welding in the pipeline through many cold bends, high-pressure flange junction without leakage, and bolts are not loose.
2, compressive resistance: normal pipe applications, high pressure flange will not be subjected to overload compression; at higher compression loads, the maximum load on the high-pressure flange is determined by the ultimate strength of the pipe.

3. Sealing mode: The core of the high-pressure flange is unique, metal to the metal of the new seal, that is, relying on the seal ring of the seal lip (T-shaped arm) of the elastic deformation of the formation of sealing, is a hard seal, and then the use of the sleeve section, card sets, sealing ring of the bones and muscles The strength of the connecting part is much greater than that of the pipe base. In the compression, the reinforcement and the lip are respectively the strength and the seal function, can not only close the seal, but also can strengthen the pipeline, greatly strengthens the connection part the overall strength.
4, Tensile resistance: In most cases, the high pressure flange in the connection is more capable of withstanding the tensile load than the pipe itself; destructive tests have proved that the flange is still intact after the pipeline has failed to withstand the tensile load.
