High temperature pipe flange repair
Problem：Leakage occurred many times in operation, forced in operation of the heat exchanger flange and high temperature pipe mouth with pressure plugging, to the device brought many unsafe factors.
Solution：High temperature disc spring 693F
Effective：Solving the loosening of bolt preload caused by temperature change and pressure change, achieve the standard of no leakage, improve the reliability of device operation, meet the requirements of continuous production, the use effect is obvious.
