100 pound LPG tank....what to do? (out of date)

[Richard]

I actually have THREE out of date 100 pound propane tanks.

I don't know how many times they can be recertified, they've already been recertified at least once. I'm debating on just buying a new trio..... if I do, the question is, what might I look at doing with these?

if I dispose of, how/where?
I've read about pouring concrete in them (after an axle is set) and essentially make them into a large lawn roller. I actually have some fields that I'd be curious to know if I could help smooth them by doing just that. Of course, cutting them would currently be an issue as they're still "empty" but have propane in them so have to void that first.... then, have no welder but that might be good excuse to buy one and learn a bit....

no planters allowed, wife already has a zillion of them and these would be vetoed by her as they're not very pretty.

No animials to convert to watering tank....

Looking for some ideas as I dwell on their future.

I bet they can be re-certified. A quick google search says 12 years after the manufacturing date and every 5 years after that. I would call a local propane company and ask. I bet it's a simple process.

Charcoal grill or smoker?

If they still have pressure [propane] in them, inspect them thoroughly for rust, especially underneath the bottom. If it is in good condition and there is no rust and no obviously repaired/painted spots, take it to your supplier. He just may fill it.

Take them to a wholesale propane supplier, not a hardware store type place. They'll either recertify them or tell you they can't be done.

I used one to make an auxiliary fuel tank for my diesel generator. Holds around 24 gal.

Cut them in half - make flower planters for your wife.

They're rusty BUT, not as horifically rusty as my 30 lb tank that they won't touch! So they might be re-certifiable (for all I know)

Sell them on Craigslist?

Nothing ventured, nothing gained I always say. Take them to a local propane filling and distribution place and I'd bet they fill them or wire brush them and paint them and then take them in. I bet they fill them and say nothing.

My 3, 500 gallon bottles are over 40 years old and I get them filled every summer when gas is less expensive and my propane distributor never says a word. Propane bottles are not like welding gas bottles where the static pressure is in the excess of 2000 pounds per square inch when full. Propane might get up to 200 pounds, maybe sitting in direct sun on a summer day.
