What kind of seal is used for fatigue conditions?
Thread Content
Ask for advice: Fatigue working conditions, variable pressure working conditions, threaded connections, consider the sealing performance of threaded connections, worry about loose sealing, consider adding seals, is it okay to add O-ring seals? Or add a soft copper seal?
What are the facilities and equipment? pipeline?
Under fatigue conditions, sometimes it is also possible to use winding gaskets for equipment flange sealing.
Except that high-pressure seals are different from ordinary seals, I have not heard of any difference between fatigue seals and ordinary seals.
The fatigue state only needs to be considered for the bolts. There is no need to consider fatigue for the seal, as long as it can be sealed under pressure.
There is no problem in using winding pads for the 1 million fatigue equipment we designed. Of course, it also depends on the pressure and temperature of your equipment. As mentioned on the 6th floor, as long as it can be sealed under the design temperature and pressure, it will be fine.
Threaded pipe connection, alternating pressure, alternating temperature, pressure 0~3MPA and temperature 25~200 degrees, I don’t know which connection method is better
