Issues regarding the calibration of safety valves
Thread Content
I would like to ask everyone: if a spring-loaded safety valve operates abnormally and opens prematurely, it needs to be removed for re-calibration； If it starts up normally, is it still necessary to remove it for verification? Are there any regulations regarding this?
Where will the safety valve open normally? Except during verification. There is now online verification available, so there’s no need to remove it, but it might not work for those that have jumped too much.
Inspection is required every year; it is a mandatory inspection that requires a report to be issued. Sometimes, once you jump off, you can’t get back; you can just use something to tap the piece under the spring
If you don’t do it, the local inspection authorities will come after you too! It will be troublesome when they come to look for you.
