Dear all
We have recently switched 3 complete cells of our ACC system.
The old ones were cut and new ones were welded.
The test that is being done (before plant startup) is a positive leak test.
We pressurize the system up to 500-700mbar (design pressure) and check pressure loss.
However, since it is a vacuum system we would like to test under vacuum conditions before plant startup.
Is there any procedure, API or recommended practice for that?
Regards,
AndreChE
