Authorized Inspector for ASME Section VIII Div.1 – verifying of NDE Procedures ?

(OP)
Hi All,

Subject:

We have to build a sphere with ASME VIII Div.1 – This sphere will be marked with the Certification Mark with the U Designator

Extracts of codes

ASME BPVC.VIII.1-2017
INSPECTION AND TESTS
UG-90 GENERAL
(c) (1) (-i) verifying that required nondestructive examinations, impact tests, and other tests have been performed
and that the results are acceptable (UG-84, UG-93, UW-50, UW-51, UW-52, and UB-44)
-------------------------------------
NB-263, RCI-1-2015 RULES FOR COMMISIONED INSPECTORS
4-2.1.8 Heat Treatment and Nondestructive Examination
Verifying all ASME BPV Code-required heat treatment and nondestructive examina¬tions are performed using accepted/approved procedures. Nondestructive
examina¬tion procedures shall be demonstrated to the satisfaction of the Authorized Inspector.
-------------------------------------------------------
Question:

At which step the AI (Authorized Inspector) should verify the NonDestructive written procedure?
1. Before the beginning of NDE works.
2. At the end of NDE works and before hydrotest.

Thank you to enlighten me on the subject.

RE: Authorized Inspector for ASME Section VIII Div.1 – verifying of NDE Procedures ?

All applicable procedures, this includes NDT and WPS/PQR should be reviewed by the AI prior to the start of fabrication.

Hi metengr

Thanks for your reply.

Best Regards

RE: Authorized Inspector for ASME Section VIII Div.1 – verifying of NDE Procedures ?

We must keep apart:
1.) demonstration of NDE procedure to the satisfaction of the Authorized Inspector.
and
2.) verifying that required nondestructive examinations and other tests have been performed and that the results are acceptable

1.) must be performed prior of any NDE on code items, because the AI must assure himself that the NDE procedure provide the NDE personnel with all necessary information to get sufficient NDE results
2.) prior to pressure test, because acc. to UG-99 "(a) A hydrostatic test shall be conducted on all vessels after .... all examinations have been performed ...."

With the exception of RT....which can show Density and IQI requirements on a production radiograph. This would be acceptable demonstration.
