Tollerances for pressure vessel

[cosmo11]

Hi guys, do you know what is the reference normative for pressure vessel positioning tollerances?
Verticality, anchor bolts position,....

Thanks a lot

Have no one of you experience in assembly?
I need to know the references for vertical vessel erection in site.

Thanks

As a common, vertical deviation tolerance is limited to 1mm/meter height but no more than 25mm at total height of vessel.
Usually it's mentioned on company standard.

Hi, the values you posted are used in common practice. I would know if there are international standard for this work area, ad well as the 31.3 forma piping erection.

Thanks

.Hi, You will find some requirements of dimensional tolerances for manufacture of pressure vessels at ASME Code
There are also standard practices as PIP whit additional requirements
Some times customer or the EPC has his owns.

Not sure for piping erection.
I just refer to ASTM A6 for verticality/waviness tolerance when prepare erection procedure for site erected storage tank.

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
