Logically, if the test gauge shows a pressure reading below the actual test pressure during calibration, means during actual hydrotest, the spools are tested at a higher pressure than actual test pressure.
So logically, no need to test the spools again.

Dear Karthik :
I have a complicated situation with pressure gauge calibration period.
During calibration test, our gauge found to be showing wrong reading (below actual). And clients ask to re-test all spool pipe tested using the gauge.
My question, is that acceptable ? luckily there are only small number of spool to be re-tested, but I cant imagine if that happens to spools that already put in service.re
Just a share, but I appreciate any coments and advise.
Best Regards
Bonardo

Can you pls Suggest as the Piping Hydrotesting Pressure gauge calibration period of time,
and also is there any code/stds governing for this.
