I'm involved with a retro-fit project that calls for 8" drips to be stubbed-in off the bottom of a 10" steam main. It's currently being determined if the main is Sch 40 or 80. The branch pipe will be a properly bevelled "fish-mouth" with a full-penetration weld connecting it to the main.
I've got my B31.1 out, and have looked at Nayyar's "Piping Handbook", but I'd like to hear from someone that has actually run the calculations for this kind of joint before. Anything special that should be considered?
