I've used Oxy/acetylene that was over 25 years old without issue. Just make sure the regulators and hoses are Actually in good shape, not leaking, not just Looks fine.I have an old, 15 years or so, oxygen/acetylene set in my shop over the years. jThe tanks look good, and as far as I can tell both tanks are still nearly full.
Is this safe to use, assuming the hoses, regulators, etc. are in good shape?
Thanks,
I bought my old Harris set used around 1990. The hoses are still fine. I'd inspect the hoses and go by the actual condition in the set. Both hoses get relatively low pressure, with the Acetylene at lower pressure than Oxygen.I have a bunch of smaller acetylene tanks that I have in a rotation for portable use. I recently used part of one that was about 12 yrs old. I wouldn't trust the hoses though.
Oxygen, Argon, NOS, Argon/CO2, and other high pressure tanks get hydro tested.I cannot answer these questions, but there is a hydrostatic test requirement every so often on the tank, I’m sure that those cylinders cannot be refilled until after the hydro is done
