Safety valve calibration
Thread Content
In continuous chemical production, the calibration of safety valves often expires after a long time, which poses safety risks to the stable operation of the system. I wonder if there are any good methods employed by various companies to address this issue?
There’s no good solution other than having the safety valve inspected when its deadline arrives.
Failing to have safety valves inspected when their validity expires is considered illegal production, and it can lead to problems if something goes wrong.
Regular verification is a good approach; otherwise, it constitutes illegal production
The installation of safety valves usually involves root valves, and backup safety valves are provided for some critical safety valves; these are replaced in a timely manner when their expiration date arrives, and the newly installed valves are then tested. This approach helps to prevent any threats to production that could arise from expired safety valves.
It is verified once during the annual overhaul. It does not affect production and ensures safety.
For the safety valves of moving equipment, reverse testing is carried out once they reach their expiration date; for stationary equipment and pipelines, shutdown testing is performed. These tasks are usually done during major overhauls, and doing them once a year does not cause any delays. Sometimes, it’s hard to avoid exceeding the specified time limits
Valve calibration is a matter of integrity··:call: I’m here to learn*··
Safety valves must be calibrated when their expiration date arrives. It’s either illegal production!
Reply to 1# memory1968: According to the new regulations, there is no requirement for an annual inspection; the RBI can assess the appropriate interval for inspection based on the circumstances.
