See this and scroll down to my comment.

Is that what you mean?

reinforcing pads as per 13480 or sockolets? - Pipelines, Piping and Fluid Mechanics engineering

Morn, I need some support with a calculation in 13480:3. We have had a failure on a 1" socket off a 10" natural gas main. We want to initially replace it like for like, but someone has questioned whether it needs a reinforcing pad. I have done the calc in excel for eq 8.4.2-1 and it confirms it...

If you are asking about insertion depth of pipe into a socket weld flange what is your construction / fabrication code ?
You will not find what you are looking for in B16.5

7.7.3 is tolerance for dimension B，while the question is about D. I didn’t find any requirement in the standard.
Depth might be a non-critical dimension and can be confirmed by manufacturer

Socket depth is usually given as a minimum. No tolerance.
