UW-40 Is telling you that you need to take into account either the thickness of the nozzle (set on), thickness of the shell or head (set thru), thickness of the repad (if applicable), thickness of the fillet welds (throat dimension). The greatest thickness being the governing thickness. In your...

That is correct. Total thickness / 4 is the governing thickness. Sec. VIII Div 1 is the same.

You can't just ignore the warning....UG-42 is there for a reason.

Is this a shell joint? If so which No. of figure 6.1 did they use? Then ask if there weld looks like the weld indicated in the figure.

Correct.

ASME Sec. II Part A

See Table QW-255.1 and subsequently QW-404.12 for the first question.

I don't use PV Elite, but looking at your snip, you are designing per ligaments (UG-53).

Correct. I'd be lying if I said I knew for sure, but the starting materials are made to a specification as well, such as SA-312 which have there own requirements for example, hydrotesting/Eddy Current.

As an addition, your client is requesting welds be RT or UT no matter if there is filler metal or not. W is only RT of filler metal welds and fitting manufacturer welds. WX/WU is all welds, filler metal or not. (5.5 and 5.6)

Yes You answered this...5.1 5.4.2 If you don't meet 5.4.3.2 or 5.4.3.3 RT is required. Table 6 may clear things up for you.

Correct. Opening size and spacing limits of UG-36 apply or use UG-39 for reinforcement.

The answer to your question is simple..... Yes. Why they would want to is harder to decipher. Way easier to roll 75mm vs 140mm.

The Code allows B16.5 flanges to be used at the pressure/temp ratings of those standards without additional calculations. B16.5 allows reducing flanges. Multiple openings do not meet B16.5 and therefore cannot be used as such. Therefore, UG-34 is required.
