plz help me to solve this probleme, for a nozzle 52in NPS (SA-350 LF2 CL2) located on the shell of PV with internal design pressure is about 59 barg and ID 4500mm (with CA= 3mm).
the thickness of the shell is t=103 mm
the allowable stress (fct of design temperature and material) is 20000psi
for these conditions i found trn=35 mm.
the nozzle is self rienforced.
so what i will do to choose the right sketch to design these nozzle from the FIG UG40??
