PVelite checks and prints tubes required thickness under internal and external pressure at the beginning of ASME TS calculation.
After the sketch of the tubesheet configuration there are elasticity material properties and then tube thickness calculation.
Not to be rude but it's not a code issue: you are missing the basic knowledge of mechanical engeneering.
Please check the difference between tensile, yield and allowable material stresses.
First of all, B16.5 pressure-rating is based only on material of construction, temperature and pressure, corrosion allowance is not rilevant. and B16.5 does not takeinto account of external loads.
The nozzle flange is subjected to external loads, so you need to include those in your calculation...
Talking about ASME div.1 u-stamped heat exchangers, I've always calculated those kind of nozzles as below:
- FEA analysis of the nozzle considering loads applied at the flange-cone junction
- Appendix 2 of ASME VIII div.1 calculation of the flange considering additional equivalent pressure due...

Vessels are not stamped but they are in total compliance with ASME code (materials, NDE, mech. calculations, welding and so on).
Then PED certificated.
Edit: forgot to mention no U-1 (MDR) needed
Hope it's more clear

Here to point out that PED doesn't necessary mean that EN13445 needs to be considered.
Calculation code doesn't matter as long as you are in compliance with PED requirements.
For example, we usually manufacture PV & HE for EU market designed acc. to ASME VIII div.1 and PED certified.
Since you...
Check local shell thk. on the bottom right: there you can add the local shell thickness to be considered for the nozzle calculation which is your lip thickness.
For the width of the lip, I would limit the material contributing to nozzle reinforcement by adding your lip outside diameter as...
