high pressure testing

[Peter Fairbrother]

Need to hydrotest a pressure vessel to about 7,000 psi plus. Any ideas
about how to do it cheaply? I don't think the grease gun trick will work...

Peter,

The usual hand hydraulic pumps used on presses and body ram kits should
be able to achieve that. The couple I have are rated to 62MPa (9000
psi). Do you think that would be any use.

A hydraulic hand pump is typically 700Bar
(* 700 14.7) ;; 10290.0
over 10,000psi
Much higher pressure than a power pumped system.
I did wonder if anyone made a chamber with an elastomer membrane, so the oil passes on pressure to water going into the vessel?
