hello everyone;

I need help about all nozzle types for pressure vessel included reinforced and not rienforced types, my need is to draw an organizational chart to help for the right choice of nozzle type on function of service or thickness of the vesel and the diametre of the nozzle.
if there is an organizational chart please share it for help in design of nozzle.

You should check out UW-16(c).....this will give you a better idea of what integral reinforcement is. As soon as you add a repad, it is no longer integral. You seem to be referring to integral as a one piece nozzle, such as a LWN. A welded nozzle can also be integral if there is enough thickness above that required for pressure to satisfy area requirements. If you need a 2" Sch 40 nozzle for design pressure, but install a 2" Sch 80, the excess thickness is considered integral reinforcement.
