Repair work
(OP)
Hello All,
I have been asked to find out first of all whether or not hydro-testing is required after repair work is done on an ASME code vessel, and secondly where this is referenced in the NBIC rules for repair.
Thanks for any help.

Which Edition and Addenda of the NBIC (or other Applicable Code)does the Jurisdiction Administration Code specify?
Once you have answered these two questions, it is just a matter of looking up the requirements in the referenced Code.
The NBIC has changed throughout the years regarding pressure testing. In every case, the Jurisdiction, through their administrative code, will have the final say as to the method of verifying pressure retaining item integrity following Repairs and Alterations.
Hydrotests are typical for the ASME Construction Codes, whereas pressure testing to verify integrity is reserved for inservice testing. Some Jurisdictions may mandate "hydrotests" instead of "pressure tests" following Repairs/Alterations.
For the older NBIC lookup paragraphs RC-2050 (Repairs) or RC-3030 (Alterations)
For the 2007 NBIC and later lookup Part 3, Section 4 Repairs and Alterations — examination and testing: paragraph 4.4 Examination and Test for Repairs and Alterations

NDE may be conducted when contamination of the pressure-retaining item by liquids is possible of when pressure testing is not practicable. Concurrence of the owner shall be obtained in addition to the Inspector and Jurisdiction where required.
