The safety valve spring is broken; please offer some guidance on how to analyze this issue
Thread Content
At a normal operating pressure of 0.2 MPa, the safety valve indicated a leakage issue; upon inspection, it was found that the spring had broken. Could someone please advise on the cause of this spring failure? Medium: Naphtha.
Overpressure, or substandard quality?
Another possible explanation is that the area froze over, causing someone to jump as a result. This fracture is due to normal wear and tear; it should be replaced when damaged, with no other factors involved. Prevent the problem with freezing ice; for the other issues, there’s little that can be done to prevent them, no specific measures available.
There is no overpressure; this safety valve has been in use for about four years
The temperature isn’t yet at the freezing point; it’s mainly because the manager wants an analysis of the root causes, so I’m looking to gather everyone’s insights
It can only be attributed to a quality issue; it was damaged due to corrosive factors.
This safety valve has been in use for about four years, so there can be no talk of quality issues
The spring is defective; it should be considered a quality issue. But after four years of use, it’s still okay. So, just replace the spring or the new safety valve. There’s no need to worry too much about it.
