Cryo? I missed that bit. Hummm why cryo temps and a pressure vessel that
big? So your super cooling the LOX to get higher density? lol idk
Well that is a problem isen't it.
The only thing I can think of would be a facility that makes cryo gases
and that does sound custom to me and 5-6k sounds pretty reasonable as
well. Too bad about the lead time but thems the breaks.

Some of those ship tanks are 6000psi but nope cryo? I cant recall if
they made any in stainless sorry, Cant help ya.

Ship utilities and starting air are STP and up, not cryo. The steels used
almost always do bad fracture toughness things at cryo temperature

If you really want/need a big pressure vessel you might try a shipyard
some ships use compressed air to start and they use something about that
size.

Hello All,
Trying to find a reliable source for some ground testing tanks. They can be
used or custom fabricated, but preferably vertical cylinder designs. Trying
to get them with specs of 80 gallon (300 liter) capacity and pressure rated
to 4350 psi (300 Bar). Material wise, looking at 304 unless someone has a
better suggestion. These tanks do need to be able to handle cryogenic
conditions as well.
I have been looking for a while and talking with some vendors, but not many
are willing to make only two of these tanks, or they have a lead time of
6-12 months. Ideally, looking for about a 2-3 month lead time and a price
that will not cause my bank to break.
Thoughts and suggestions very welcome!
Thank you in advance for the guidance.
Cheers,
Brian
