Application Scope
The flange joints of pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes and hand holes in petroleum, chemical industry, metallurgy, electric power, ships, machinery and other industries are sealed.
Use of:
the use of Temperature: -196 ° C -650 ° C (Oxidation medium does not exceed 450 ° C)
the use of pressure ≤ 25MPa gasket thickness :2.5-4.5 mm
Performance:
1, the scope of application-Canton. Can high temperatures, high pressure and adapt to ultra-low-temperature vacuum or
use.
2, the ability of compensation. At high temperature, high pressure fluctuations frequent-position, the sealing performance
stability and reliability.
3, a good sealing performance.
4, the use of the installation convenience
