Vacuum Vessel Design
Vacuum Vessel Design
(OP)
I was wondering about design calculations for vacuum tanks loaded on trucks and their associated vacuum line accessories. At uni, I only ever worked on pressure vessels, and all calculations were based on a higher internal pressure than their surrounding atmosphere. Will these equations be the same for vacuum? Is there any standards in Australia on this type of design? Any thoughts?





RE: Vacuum Vessel Design
Vacuum vessels can fail by buckling. This mode of failure is typically not addressed using standard hoop stress calcs etc.
Try have a look at ASME VIII, Div 1, UG-28 through UG-30. Unfortunately this is the only code I could point you to.

RE: Vacuum Vessel Design
What ever pressure vessel code you use in Australia will likely have a section about vacuum, or it may be called vessels under external pressure.
Good luck,

I haven't had any involvement with transportable vessels, so it would be wise to check local or federal regulations in that respect, for any other requirements.
