How long does the pressure retention test for pressure vessels last?
““Long enough time”? It’s really hard to tell...
Container sizes vary, and the number of welds, pipe ends, etc. is not fixed; it’s impossible to make generalizations. As long as all areas that need to be inspected are thoroughly checked, that’s sufficient.

This needs to be determined by oneself; the tolerance specifications do not provide specific requirements
Generally, it is sufficient to complete inspections of all the areas that need to be checked; we usually take half an hour for this
It depends on the specific conditions of the tank
The standard does not specify this clearly; it is up to individual discretion. The inspection is considered complete once it is found to be satisfactory.
There is no specific time; it’s sufficient to ensure that all welding joints and sealing surfaces are inspected
In accordance with clause 11.5.3.3 of GB150, it is considered acceptable as long as no leaks are detected in all welded joints and connections after inspection. Based on experience, if the materials used in the equipment have a tendency to crack over time, it is advisable to extend the holding time to 10–30 minutes.
