Since appendix 1-10 has now been removed from the 2107 edition of the Div code, we now go to use Div 2 part 4.5 for larger nozzles (ratio greater then 0.7 to 1). Which material allowable stress shall we use now , Div 1? Div 2? Vessel design code is Div 1.
Unless something has superseded it, I believe this would fall to code case 2695. Div 1 allowable stresses still apply, along with other rules. See the code case.
Above is a snippet.
