Tollerances for pressure vessel

[QUOTE=cosmo11;260737]Hi, I have found ASTM A6 but my version is "Standard Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling".
Do you have different reference? Can you share it?

Thanks[/QUOTE]

Use verticality and waviness tolerance table in that standard.

Hi, I think that A6 reference talks about tollerances for manufacturer or for purchaser for structural steel. So I don't think that these tablea can be used for erection tollerances of vessels, but I would like to konw yours opinion.

Thanks a lot

Hi, did you find a specific phrases which mention that the standard are used for manufacturer and or purchaser only?
IMHO since no phrases mentioned, we still can use the standard.
I used that standard for erection of site erected storage tank, and site erected tanks is different with pressure vessel.

in CODAP French code, you can find high dimensional tolerance for horizontal and vertical pressure vessel.
