what to do with co2 tanks. i have no idea.

[JKR]

Just a question regarding tanks falling below the 2" diameter limit...

Unless there is a change I am unaware of, these tanks are exempt from rehydro'ing. Is metal fatigue an issue with these tanks? It seems that this law would apply to all tanks as I doubt that there is any difference in the wall thickness or metallurgy.

Just curious...

Can't answer JKR's question but my opinion on the issue is that hey, it is required by law so abviously it should be done. We have welding gas tanks at school that if for some reason they should go off its not a matter of what it will do its a matter of where in the building it will end up. High pressure is nothing to fool with.

they make a nice low pressure chamber for a LAW

so one of the local fields now checks hydro on co2 tanks, how lame is that. co2 tanks have a 3 year hydro right? if so mine are out of it. what do i do with them? i wouldn't feel right throwing them out, and don't really want to buy new ones. maybe a small one for playing pump.

anything i can really do with them except have some paperweights? maybe turn them into art?

I re-hydro my tanks. For a 20oz, it's like $5-$7 less than a new one, something like that ... however, I have 2 tanks that are about 12 years old, so it's saved me a couple of bucks and I like having all those dates on them. Except for the last time at a field, the kid didn't want to fill one because the first date said 1992, even though the last hydro was 2004. He had the i.q. of celery though (c:

Tanks very rarely fail. The chances of it failing a re-hydro are so small it's worth it to do it, at least for me. I've probably only saved $40 over the years, but what the hell, it's still forty bucks. A couple of my tanks have anti-syphon too, that's a consideration but not a main one since it's so easy to put in.

A CO2 tank, well taken care of and hydroed regularly, has an ulimited lifespan according to the DOT.

I don't see the point in creating the waste of scrapping your "old" tanks in favor of new ones just to avoid hydroing them. If it is the same price, or cheaper, why not just hydro?

what i like to do is fill them ups w/ gun powder and blow them up

(bury them first lol)

I dont personally own any co2 tanks, but I can see someone making a point that if it is the same price why not buy a new one thats in perfect condition.

Anyone have a link for the DOT section on tanks? I ran a search and found everything but it.

I have a 16oz steel pumpkin that I'm pretty sure doesn't have to be tested. I thought I read it somewhere that steel tanks were exempt.

Steel tanks are not exempt, they just have different requirments.

If you have any questions refer to the fine folks at:

Hydrotester.com

Send them an email and they will answer all of your questions.

My point is, why buy new ones if you don't have to? Unless your tanks are just totally beat to crap, then why wouldn't you buy new ones...

Ahh, but his point comes across to me as more one of enviromental responsibility. Why throw away something that you do not need to and replace it with new? Why waste the materials that go into its construction and create that waste and disposal?

It does seem like a aweful waste to throw away perfectly good tanks. They do have a certain lifespan though ... you can only put the date stamp on the neck, not on the sides, so once you run out you can't hydro anymore. So, figure what, about 80 years or so before you run out of space?

Even though there is a lot of aluminum on the Earth, aluminum is rarely found in a natural state ... in fact, there was a time it was worth more than platinum. It takes huge amounts of electricity to get aluminum out of the soil ... so, you'll be saving some fossil fuel too by "recycling" your aluminum tanks. If that doesn't float your boat just think of it as a small little F.U. to the middle east (c:

Well, as a frugal kind of guy, I have to disagree with the above! Hydro your tank, especially if it is anti-siphoned.

I don't spend huge amounts on paint and probably won't be buying a new 'gun for a long time.

Okay, I didn't expect that kind of crappy answer from you, Sam; or, maybe I did...
