Hydro test of pressure vessel with scaffolding inside
Hydro test of pressure vessel with scaffolding inside
(OP)
Dear friends,
one of our fabricator is insisting on conducting hydrotest on a vessel at shop (designed to ASME Sec VIII), with scaffolding fixed inside. they do not intend to remove the scaffolding.
Can someone throw some clarity on this, how decision to be taken OR pros & cons be established

Of its just access to do things after hydro I can't see too many issues but the devil is in the detail. Any drawings?
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

@ironic metallurgist & r6155: the main concern I find is that the packing/pads used to fix scaffolding inside the vessel should not mask a leak in the vessel. also, scaffolding pipes are hollow, not sure whether its safe to have a pressurized water around hollow pipes.
Thanks all of you

As others have pointed out, you have to check to make sure the scaffolding is secured. Are the pads and scaffold rated for the pressure?
Is there a liner or coating inside the equipment? if so, make sure the scaffold doesn't damage that during the test.

If no, then the manufacturer is quite noble not to put anything else inside the vessel apart from scaffolding and going ahead with hydrotest.
Hope they remove the scaffolding without resorting to any hot job or grinding or even cold cutting.
Also pray that an internal inspection is carried out after scaffolding removal.
