Steel tanks from an auction

[PirateChance]

I just got two steel tanks from an auction, they appear to be in reasonably good shape (Heavy as sin though) I don't see any corrosion or discoloration.

I'm not sure how old they are, or anything about them, but if I get them hydrostaticly tested should they be okay? Is there anything I should look for? My dive instructor went over tanks pretty thoroughly but that was a year ago, and I haven't dug out my text book yet.


Thanks!

If they pass hydro and VIP, then they will be okay. If you look on the neck you should be able to find all of the information about what size they are, material, manufacturer and date manufactured.

I hope they pass without any problems.

First step might be to determine if they are SCUBA tanks.

Years ago, my brother brought home a cylinder that his employer had discarded. It was a "Radar transmitter gas" filling tank. It appeared to have SCUBA possibilities, but it would not mate up with any SCUBA valve we could find.

Good luck with them.

They are indeed scuba tanks they came configured as doubles but I would like to break them down and use them as singles. They are rated for 3000 PSI, so that is standard.

I'm breaking out my textbook now to see if I can decipher the rest of the info on the tanks, I took the boots off and so far no corrosion! I can't believe I got them for $10! Anyone know a good guide to how tanks are labeled?

3000 psi isn't always standard for steel tanks.

you'll often see steel tanks rated at 2250psi, 2400psi, 3000psi, 3180psi, 3442psi or 3500psi.


standard 3000psi is more common with an AL 80.


post all the imprinted info from the tanks here and we'll help you decifer.



This should help if you want to peel through it yourself

Also this one for Aluminum tanks for reference for others

I guess I meant more mid-range than standard, I was saying it was not a LP or HP tank. It's DOT certified, but the rest will have to wait until the morning, and more light.

Thanks every for the great guide, it supplements the the I found nicely.

and, once again, Holy c**p $10!
It's possible that I'm a little excited

If you photograph that "doubles equipment" that you won't be using, and post it on this bord, you might get a sale. Folks are often looking for that.

Its a manifold and tank bands, but I'm pretty sure I see a J valve on the manifold

You think anyone would want any of it? I'll take some pictures after I find the camera charger.

The setup looks like these Scuba Tank Steel Doubles - eBay (item 200366818384 end time Aug-01-09 12:16:00 PDT)

Except they have a seperate knob on the other tank as well. - I'm still looking for my camera charger, I don't have a clue where my wife put it

I only said J valve because of the valve you can trigger by pulling down on the pull on the side of the tank, I guess that may be for turning on the second tank. Any one know?

Thanks!

There are vintage SCUBA enthusiasts that will get a big charge out of what you have. Post a photo and you'll soon know all about it.
