Pressure testing with nitrogen
A colleague mentioned the other day how he tests with nitrogen.
Usually pressure can drop or rise with different ambient temps.
This may not be a new idea but isolating pressure gauge from system while system under pressure test, then say next day pressure is checked & compared, if gauge pressure is lower than day before, open valve & check system pressure compared to gauge pressure.
If the same system & isolated gauge, no leaks.
sound feasible?
