Our facility has spares for each safety valve
It is necessary to determine whether the valve has internal leakage； If there is an internal leak, a blind flange must be installed to prevent the escape of combustible gases.
Safety valves must be available as spares; safety accessories for in-service special equipment are essential, and they also have expiration dates for inspection.
Is there no backup? Isolating with a blind flange directly is too dangerous for the container
There is no spare safety valve on site. Are there standard requirements that require a spare one?
The operating pressure vessel has intact safety accessories, and its inspections are within validity. This is a requirement for safety standardization. Do you think it’s necessary to prepare one? Unless your device is disabled, it’s better to buy a new one, have it tested, and then replace it. You should know how much the work safety supervision agency imposes as a fine. Do your environmental and safety officers know about this?
