Hi all

i had some questions on use of ASME B31J on Branch connections mainly 45 Deg. branches. mainly the below queries.

1) is B31J applicable for branches in same plane of header to 45 Deg or
less than 45 Deg
2) is the applicability limited to D/T < 50 and d/D<= 0.6 . i had
understood the applicability to D/T <=100 for 90 deg branches but not
sure for 45 Deg.

have attached a sketch for reference
