When performing a pneumatic leak test on the device, must the safety valve be reinstalled in place?
No, but the airtight pressure must not exceed the set pressure value of the safety valve. Once construction begins, the safety valve must be installed in place and put into operation.
Could you explain in more detail upstairs? Why?
I personally think it’s necessary; after all, when there is a need for airtightness, it must be maintained at the operating pressure. At that point, the safety valve is needed to prevent the equipment from exceeding pressure limits. It would be bad if the pressure rose too high, and this is also an opportunity to test the tightness of the safety valve as well as to ensure its airtightness.
