Pressure Containment vessel 1

[Kramnaganalf]

Hi all,

I am looking to manufacture a vessule capable of containing a burst pressure of 35,000 PSI and was wondering what calculations I should use.
Can anyone advise?

The inital vessel would be quite small, approx 200mm x 200mm x 500mm, however I would like to consider making this 200mm x 2000mm x 500mm.

The fluid volume would also be relatively small, approx 1-2 litres of a water based fluid, so the containment vessel requirement is simply for any projectile rather than fluid pressure.

Kramna..,
If this is not something to hurt other people and does not make a big bang at any stage of its operation, then it can be considered as a pressure vessel, with additional info. Please define burst pressure (is it a detonation inside the chamber, is it a pressurised liquid rushing into the "vessel", from ambient pressure to 35,000 psi, has the vessel any particular shape (is it the shape of revolution with a centerline or some axis of simmetry). Please, the word "projectile" linked to 35,000 psi reminds me of Hiroshima..

To clarify,
We are to test a component to 35,000 psi.
I am looking to manufacture a vessel that will house this component during testing.
If the component were to fail i.e. weld shears, and part of the component was projected by a hydraulic pressure of 35,000 PSI, what calculation would I need to consider to ensure that the vessel contains the projected component.

The shape of the testing vessel is available, however I was considering a rectangular box type as this may allow additional components to be tested at the same time

I used to test compressor cylinders to destruction. We used an enclosure made of heavy bar grating. Even though cylinders were tested with oil, it sometimes looked as though someone had put a grenade inside, when they let go. We had to repair it a few times, but it never failed. Using multiple layers and offsetting them allows pressure to dissipate while retaining any metal. Make it plenty big.

I think your rectangular box will become round.

Why not to design this tank by FEA per Appendix 4 of ASME VIII-2?

To a rectangular tank FEA modeling is not a big issue.

Your application really shouldn't require the container to sustain 35,000 psi, nor should it require something like a bomb-containment chamber. FJTom sounds like he's got the right approach. You might consider testing in a pit or using sandbags around it as other options.
