    I have a bunch of old forktruck propane tanks at work that we cannot get filled anymore. I was looking at one today and thought it would be a ducky compressed air storage tank. I know propane is stored at a low pressure (40 lbs?) since it is a liquid. Anyone ever think of converting one to air storage?

    If they're too unsafe to put propane in, they're way too unsafe to put air in at high pressure.

    They are in pretty good shape. There is a "life expencatancy" to a propane tank regardless of its condition, after its time is up (determinied by the stamped year) they will not refill it regardless of condition.

    Have you heard about re-ceritification ?
    Some say it can be done for less than 8 dollars !

    Yes! Use them!Propane tanks are pressure tested to three times their rating for certification. Air is not combustible, so go right ahead. Have you ever seen an expiry date on an air tank?

    My uncle uses a pair of expired forktruck tanks for his home-built compressor. Another fellow at the shop uses an expired 60-gallon one together with 20-gallon compressor for extra reserve.

    Only thing is your air tools will smell like propane for a while. Yuk!

    There is a test/expiration date on air tanks, but for non-commercial use it's pretty hard to enforce.

    If the shoe fits, get another one just like it
