Thickness Transitios in Nozzles
Thickness Transitios in Nozzles
(OP)
Ok you pressure vessel experts out there. I have a good one for you.
Section VIII, Div. 1, Figure UW-13.4 shows typical transition details for attaching nozzles to piping of lesser wall thickness. In both sketches, it shows a 1/4" minimum radius at the angle intersections. Is this setting a precedent for all transitions? Is there any other place in The Code where transition radii are specified?
Your comments are greatly appreciated.

The attachments I was concerned about are indeed forgings but they are machined for each specific application/attachment. My concern was that it appeared to me that The Code was now specifying that a minimum 1/4" radius was required for all transitions. I visited with our AI yesterday about this and he tells me that Figure UW-13.4 is referring only to a weld prep and that I am not to worry about it.
Thanks again and have a great day!

I respect your opinion, but where can I find this in the code except for this figure?
