Hello,
I've done a little bit of digging to try and find an answer to my question but have so far come up empty handed. Perhaps the answer is so simple that nobody has thought to ask, in which case this should be a quick and easy one to put to rest. My question pertains to ASME Section VIII Div. 1.
When there is a nozzle that is centrally located in a head (IE top dead center), how should one interpret UG-40(c) when it talks about measuring the limit of reinforcement from "...the contour of the surface at a distance from each surface equal to the smaller of..."? If the nozzle were in a shell, I can see it simply being from the high point of the shell. In a head, however, would this "high point" be the top of the head that no longer exists, or from the top of the existing contour that mates up to the nozzle outside wall, similar to what Figure UG-37.1 seems to be implying?
I found an interpretation (VIII-1-07-21), but it is equally as clear as mud to me.
I appreciate your feedback.
