Safety valve replacement cycle
Thread Content
Is there a replacement cycle for safety valves? My workshop has been in operation for 10 years, and most of these valves haven’t been replaced yet. Is there any mandatory requirement for this? Generally, we first attempt to repair them if they fail the inspection; if repair isn’t possible, then we replace them
This is different from a safety helmet, right? It has a specified time after which it must be retired； The safety valve must be calibrated once a year; it can be used once the inspection is passed.
Is it the same as pressure vessels – as long as the mandatory inspection is passed, they can be continued to be used?
There are no strict requirements; as long as it passes the inspection, it’s fine. Some of our safety valves are already 20 years old. Those that were replaced were so because the verification showed that grinding was no longer possible.
As one of the four essential safety accessories for pressure vessels, safety valves must have a regular calibration system in place to ensure that such safety accessories can perform their functions properly!
Shouldn’t safety valves be calibrated every six months?
Safety valves should generally be calibrated at least once a year
Safety valves should be regularly calibrated and pressure-tested. There is no requirement for regular replacement.
Regular calibration can also be understood as another form of replacement!
Safety helmets must be retired after 3 years, but some new ones are not available; it’s a shame to retire them
