I am so sorry you see that way and I still disagree. If this discussion continues, it only demonstrates there is no agreement about this topic yet, which is in line with my last 14 years work experience worldwide in this.
Regarding the application of MR0175 to upstream and MR0103...
@david339933
Yes, seems you are right regarding the NDE requirements for root passes. I had missed it with most customer specifications (like Shells, Aramco..) which always refers to NACE standard, my bad here.
Regarding the cracks, I agree with you that no visual crack is acceptable, and this...

Sorry for my ignorance, but as I know ASME allows certain cracks size and number in welds depending on the service and class of inspection. Correct me if I am wrong. Here we mostly cover all other non ASME requirements such as NACE ones, more stringent than ASME.

As the subject of the post indicates, this is just a hint.
I am very clear about these requirements and where do they come from, also for which service they are applicable for.
Unfortunately, most customers/end users don't understand the specifications written by i.e. Woods (former...

Dear all, in reference with the above subject, please do note that the NDT guy can be right by requesting PT on a root weld.
It is true ASME doesnt require such, but it is equally true that additional standards such as NACE MR0175 or NACE MR0103, referring to NACE SP0472...
