Dear All,
I would like to seek your opinion, understanding and or feedback with regard to the following question
We have a case here where the weld joint required to undergo a repair on a pipe weld due to the radiography taken. There is an approved weld repair procedure which allows us to grind or gouge out the defective area and re-weld with the same approved WPS. This is acceptable to the customer / end user. There is no issue here.
However, in another scenario, we discovered some misalignment on the pipe line/ spool during the assembly stage and we grind or gouge part of the weldment and re-weld it back to the correctness or straightness of the line. There is no procedure being submitted in the first place.
We have submitted a NCR and it was accepted by the third party representative but was rejected outright by the end user for failure to provide an approved (re-alignment) procedure and also failed to inform them (customer) in advance prior to any re-work to realign the pipe line (on a gas compressor skid assembly package)
Question :-
1. Does anyone have any previous experience on what should be carried out for the realignment of the pipe spool or line? Please share.
2. The customer’s specifications does not clearly indicate this case scenario for further rectification action and we believe that their specifications does not address this subject, so therefore, it is rejectable by the customer?
3. Does anyone recall such (experience) issues from the ANSI B31.3 which the pipe spools is based on for the manufacturing and testing?
Thank you in advance for sharing with us
Thank you
Best Regards
