RE: [PSUBS-MAILIST] small item pressure chamber

["roger" <rjune@fuse.net>]

You can make a chamber from a 6000 psi gas bottle.
They are tested to 10000 psi typically.
They are easy to obtain, and not to expensive.
Get a bottle that was used for argon or some other inert gas.
Cut it in half, weld the appropriately sized bolt flanges
(with o-ring groove in one flange), to each half.
weld a couple rings to the outside of the tank,
spaced evenly along the body, to increase the
presure rating of the tank (safety factor).
You can plumb your high pressure supply line to the valve
that comes with the tank.

These are the basics for building the tank.
There are a lot of little details that need to happen
when building and dealing with high pressure air.

Always use caution when building or using equipment
for high presure air.

does anyone have a 1000 psi or greater pressure test chamber (at least 2
feet long, 9 inches wide) for use to test small submersible components? Does
anyone have any designs on how to build something like this?  Any tips?

Thanks,
