Need a unique type of pressure vessel

AI Thread Summary
A user is seeking a unique pressure vessel capable of holding at least 32 fluid ounces and withstanding 100 psi of internal pressure without deforming. They have ruled out pressure cookers due to sealing issues and are unsure if a Nalgene bottle would be strong enough. Suggestions include using a short piece of steel pipe with threaded ends, which can be customized with adapters and caps. The user has attempted this method but struggled to find the right pipe size at local stores, although McMaster-Carr offers suitable options. The discussion emphasizes the need for a robust, leak-proof solution for their experimental requirements.

I have a very odd need for an experiment I'm doing. I require a container of at least 32 fluid ounce volume that is very rigid and strong; it needs to be able to resist preferably at least 100psi internal pressure (water will be inside) without deforming. The opening needs to be at least 2" in diameter.

I've tried a pressure cooker; but the seal on those do not prevent liquid from seeping out. I'm afriad a nalgene bottle won't be strong enough (but that geometry is ideal).

I really can't think of anything that exists that meets these needs; I'm afraid I might have to rig one up myself using an old pressurized gas tank... unless you have any ideas!

Thanks
Dan

I'd suggest just getting a short piece of steel pipe, threaded both ends (pipe thread) and then attach adapters and/or caps to the ends.

Take a look in http://www.mcmaster.com/#"for pipe. Or just go to your local hardware store and see what you can find. You should be able to make what you need for less than 50 bucks.

Thank you for the website! I can't believe I haven't seen that before. I have tried the method you suggest, but it didn't work since I couldn't find wide enough pipe at Home Depot. McMaster Carr does have acceptable pipe sizes though.
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
