Compressive Buckling in Vacuum Pipelines and Tanks

[LBishop]

I was wondering if someone could point me in the right direction with a small prolem related to vacuum systems and buckling.

Basically, I'm trying to find a model that can produce the buckling limits of thin walled vessels or pipes subject to compression. Does such a thing even exist?

My searches so far have come up empty, the only promising lead was blocked by my employer anti-spam system so any inisight would be greatly appreciated.

You could look at a pressure vessel design code such as ASME 8 or whatever the original design code was.

Yes, ASME section 8 (VIII for the purists) part UG-28 is a good place to start.

I am a little confused...

By "looking for a model".....what exactly do you mean ?

(This sounds a lot like MBA psychobabble...)

If you are looking for a methodology...ASME VIII

If you are looking for an explanation, I suggest:

- Bednar; "Pressure Vessel Design handbook"
- Megusy; "Pressure Vessel handbook"

API casing and tubing (5CT) has collapse ratings; I can't be specific but there are procedures for making the calculations in some API document.

I think you've all put me on the right track.

Thanks for the help.

Google "pipe collapse pressure", if you're looking for external pressure caused effects in the transverse direction, as what might be termed "ring collapse". "Compressive buckling" would normally indicate your interest was in the axial direction and you were looking for the Euler buckling load of the pipe column.

As "Big" " indicates; there is collapse and buckling. Well casing and tubing is (should be) checked for collapse, buckling, (and burst and tensile load). So , I expect API 5 will have guidelines for calculations (not my background).
