Welding Nozzles
Welding Nozzles
(OP)
Hello, I need to design a horizontal pressure vessel on saddles. It must contain 3500 gallons of ethyl mercaptan at 30 psi. A manhole and nozzle connections must be provided. As a beginner on pressure vessel calculation I have a basic question. Which is the criteria to choose a weld with a partial penetration or full penetration at nozzle?.
Thanks.
Thanks.

I suggest that you specify an ASME Section VIII vessel and leave the welding details to the fabricator. Full penn welds are required by the ASME code.
You can get a good quality vessel by:
- getting a good datasheet filled out
- providing a sketch
- Specify MAWP, materials, nozzle sizes, manway size ,coatings, support points etc.
Call up a fabricator and begin talking

full penetration but just abutting fillets. considering the material hauling you specify, you shall make the vessel to hold for longevity.
I would use a true groove design, it's better to be safe than sorry.
