pressure vessel cert requirement
pressure vessel cert requirement
(OP)
Hello, I just found this forum and this seems like a very informative site!
I have a question concerning testing and certification requirements for a pressure vessel. I am designing a testing rig to pressure test vessels before placing them back in service. The test rig is to be made of a 2" diameter by 12" long piece of stainless pipe with four 3/4" air connection fittings welded to the 2" pipe. This setup will be regulated to 30psi, never any higher. Very simple design to do a simple job.
I need to know what testing and certifications this test rig would need to undergo? Are there any rules for this?
Thanks for the info.

Also, I don't know your local regs: that manifold may be considered a fitting (or, maybe, a pressure vessel even) that would require additional certification of compliance;.
Be very carefull about the "Very simple design to do a simple job." It might be just a bit more complicated than you think. I saw people in the field being hurt by those small things.
Good luck.

calculate it for the required pressure and temp,
no cert is neede,
ask your AI

It is indeed a very informative site - it makes me realise how narrow and specialised is my engineering knowledge - there are so many posters here who have really given me an insight in to different fields.
On your topic, I recall a thread here about the safety advantages of hydrotest over pneumatic test. You mention air connection fittings in your OP. Have you ruled out the possibility of hydrotest? If you run a search here you will find a lot of useful information and warnings!
