Nozzle design

Nozzle design

Nozzle design

(OP)
Hello everyone;
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??

RE: Nozzle design

HOUARI YAHIAOUI, I'm not going to check your numbers, but you should be looking at UW-16 for the design of this detail rather than Fig UG-40.

You could perhaps use Fig UW-16(b), weld thru the nozzle neck, but sketches (e) or (g), weld thru the vessel wall would be more often used.

Matter of shop preference and/or contract requirements more than anything.

Regards,

Mike

The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: Nozzle design

Big stuff !!!

Can you share with us sketches of your final design ....

Is this a repair on an existing pressure vessel ???
