Performance features:
1. This product can reduce the vibration and noise of the piping system greatly. It is a fundamental solution to interface displacement, axial expansion, non-concentricity and other problems of various types of piping system.
2. It can be made into various kinds of acid proof, alkali proof, corrosion resistance, oil proof and heat resistance according to different materials, suitable to manifold medium and environment.
3. The material is polar rubber with the performance of good sealing effect, light weight, easy installation and repairing and long service life. But keep it away from sharp metal instruments in case puncturing the sphere.
4. If it is used superterraneanly, can be equipped with an flexible stents, tighten the bolts in diagonal method when installation
5. When the pressure of pipe line is too high, should use high-point bolts to connect the two flanges.
