Features:

1.High strength: can withstand greater pressure and fastening force, not easy to deformation.

2. High temperature and high pressure resistance: it can still maintain good sealing performance and mechanical properties under high temperature and high pressure environment.

3. Corrosion resistance: It has good resistance to some corrosive media.

4. Good resilience: After tightening, it can maintain a certain elasticity to compensate for the small displacement of the sealing surface caused by temperature changes or mechanical vibration.

5. Reliable sealing performance: can effectively prevent medium leakage.
