Pressure Vessel certificate requirement of re-certification (by IA) and re-inspection

[yogiemaradona]

Dear Experts,

I have just inspected compressor package that contained pressure vessel with expired certificate from Authorized Inspector (IA), Further I have to decide whether this compressor can be used or not.

Having discussion somebody suggest me that enough only to conduct re-inspection instead of re-certification, this statement make me little bit confused since I am not sure this re-inspection which only encompassing MPI and NDE (100%RT/PT/MT) certificate can be used as justification to replace IA certificate.

Please somebody help and advice me on this mater.


Thanks,
Yogie. M

Looks that you need an operation permit,certificate and should not mention an ASME inspection by an A.I. Authorize inspectors are for new ASME Construction r National Bard repairs or alterations. yours may be just a Jurisdictional,Local inspection.

GenB,

Correct I need operating permit or certificate, then local inspection by doing 100%NDE, MPI and UT can be used for this permit.

Thank you for your explanation.

What are your jurisdictional requirements?

Dear Ripz,

Actually I am not sure about what are the complete set of this jurisdictional requirements, what I am always to do just to conduct 100%NDE, MPI and UT to confirm there are no defect or significant lose of thickness i.e. still comply to its MAWP.

Could you please tell me are there any requirement still missing for this purpose.


Thanks,

What I meant was if your Country/State demands that you need certain requirements for inspection or need to "certify" the vessel via an Authorised Inspector, for certain types of vessels then that is what you have to do.

If it doesn't, then you can look at what you as the inspection agency believes is adequate for this vessel based on service conditions and material of construction. If you say you did 100% RT/PT/MT on this Compressed Air Vessel, that may be adequate. I would remove the PT and include UT Thickness. MT should pick up everything the PT would.

...

Where I live, our outdated Pressure Vessel law indicates that we Certify our Compressed Air Vessels and Boilers by an inspection by a Government Authorised inspector, who usually is an Authorised Inspector.

For all our other vessels, this IA certification is not mandatory. And inspections are done based on our internal inspection department's risk assessment.
