Seeking assistance with the inspection of safety valves for special equipment
Thread Content
Dear sea friends, can the safety valve on special equipment be removed for inspection after shutting off the root valve, without having to stop operations? Generally, verification takes 2-3 days. Is that acceptable in this case?
The purpose of the dual safety valves becomes apparent at this point!
Won’t an accident occur in the next couple of days if the equipment doesn’t have any safety attachments? Just install the spare parts, that’s it
At this time, it is also best to replace the double safety valves with ones that have already been calibrated; the replaced safety valves should be sent for calibration to serve as spares
Yes, the basic definition of device safety protection measures
No, it’s not okay. If nothing happens, it’s fine; but if something goes wrong, it’s all over
No, for equipment that does not allow shutdown, it is best to use one with dual safety valves
Use dual safety valves, or have a calibration institution perform online calibration
Secretly take it apart, fix it, and then put it back together
No, that would constitute the unauthorized disactivation of safety facilities, which is a serious hazard. It can be checked during maintenance. It can also be checked online, at a slightly higher cost.
