They are rated for 3000 psi generally and there are bound to be some at some scrappy’s yard. If you can get a 70 litre or such then chop off the top and weld a couple of plates on. They are at least 10” inside diameter. I have a couple marked for test chambers. Good for at least 5000 ft depth test pressure.
