High pressure flange is used for connecting pipes or equipment with pressure higher than 10MPa. At present, it mainly includes traditional high-pressure flange and high-pressure self tightening flange.
High pressure flange is a part that uses the plastic deformation of the sealing gasket (elliptical gasket, octagonal gasket, lens gasket, etc.) to achieve the sealing effect, and is connected to the pipe end to connect the pipe with the pipe. There are holes on the flange, and the two flanges are tightly connected by stud bolts.

1. The sealing principle belongs to plastic deformation.
2. Connected by bolts.
3. Bolts should bear tensile force, temperature difference stress, bending moment, torque and many other external stresses.
4. The volume is huge, the weight is heavy, and the installation and positioning is very difficult.
5. The sealing performance is unstable, especially under harsh conditions (high temperature, high pressure and highly toxic medium), it is easy to leak, resulting in serious consequences.
