When my oxygen tank was recertified, they told me the pressure (hydro) test
was at 4000 PSI. (Tanks are usually filled to around 2500 around here)
Also, is it the Oxygen tank that is rusty, or the Acet. tank? (or both).
Personally, I would get the tanks clean (If wire brushing, make sure no
fumes are leaking from the flammable gas tank!! I'm not sure I would even
want to try wire brushing.) , paint them, then take them in to be
tested-tell the place you want both tanks tested, and why (The rust).
Specify that the Acet. tank be tested, as one place I deal with said the
lower pressure tanks are not usually tested (ie flammable gases-acet is
usually 250PSI)
Good luck! Scott M Ryan
