ASME Section I - Use of PAUT on less than 13mm wt?

Hello forum,
Has any of our members / contributors had success is applying PAUT on ASME I scope of works for thicknesses less than 13mm?
My understanding of CC2235 is that it allowed for PAUT to be utlised on thicknesses greater than 13mm. This was then incorporated into the Code. Has there been any ratification for thicknesses below?

What are the experiences and limitations observed when using, for example, the COBRA system with the OMNISCAN MX2? Is it effective for replacement of RT on wall thicknesses below 13mm?

Hi Steven.
In ASME 1 / Edi. 2013. The use of any UT technique in lieu of RT is not permitted for thickness > 13 mm.

In my previous post there is a misprint.
Where is indicated > 13 mm, it is meant < 13 mm.
My apologies

Steven:
Are you talking about using PAUT on boiler tubes?

Stan,
Not in particular, no. I was discussing, in general.
Diego has answered my question. I am now looking, based on Figure 100.1.2(B), at how much of the Erection work on our 24 Boilers will be effected by this. My guess is very little, if any, but will know definitively very soon.

Thanks all.
