(OP)
Is online relief valve pop test taken up in process gas boilers/steam generators, like Hydrogen plant naphtha-reformer steam gen or sulfur condensers ?
Some inspectors are insisting on this (inpectors are with mechanical background)

RE: Online relief valve pop tests
For new furnaces, there are chances the PSV cannot resit. On older furnaces, the PSV may be passing badly that it will relieve prematurely.
We carry out pop test for our co-gen HRSG as well for the same reasons. But at 600 psig, the likelihood of failure is lower.
