Hi,
I have a question regarding performing NDE on the vessel joints.
The Code requirement is to do NDE (RT & UT) before PWHT. Out Client's spec requires it before and after PWHT. The Vendor (due to extremely, uncompromisingly tight schedule) offered to perform it as per Code, before PWHT, and mag particle test after. Our Client mentioned that they doesn't care if NDE was performed before PWHT, but they definetely want them to do it after, just to make sure that they provide "QUALITY PRODUCT WITHOUT DEFECTS". Manufacturer is very reluctant to do NDE after PWHT, their argumentation is "what if we will find some defects, and will have to repair and re-PWHT again, and what if we will find defects again..."(??!!). I assume that if Code required NDE only before PWHT, it means that the possibility of the appearence of the new defects is very low. Am I right?
Please, share with me your considerations.
Thanks!
