Attaching a nozzle to shell using only fillet welds from the outside
Attaching a nozzle to shell using only fillet welds from the outside
(OP)
Hey Everybody:
Has anyone ever attached a nozzle to a cylindrical shell while only performing an external fillet weld? I want to do this for an alteration, and while I think I can, just wanted to see if anyone has done this before. Can you do it without any weld inspection if you are under DPS6 using FIg. UW-16.1(u)?

A fillet welded nozzle is always a simpler and cheaper way to make a nozzle on a pressure vessel.
Unfortunately, ASME and EN pressure vessel codes do not permit this type of weld in this nozzle size.
Also, the schedule 5S nozzle seems like a very bad choice here. 5S piping is nearly impossible to properly weld.....IMHO
A schedule 40S nozzle with a slip-on flange would be the best choice here.
