@CheckThisOutFoo Air is a breathing gas, and you have also Nitrox which is air enriched with oxygen, Trimix, and more exotic mixes which are very far from common air (80% nitrogen 20% oxygen) for very deep underwater work.
Very interesting. But some comments on the hydrostatic testing are slightly off. They use water in the tank because water is incompressible. They fill the tank with water and apply 5/3 the maximum working pressure (around 250bar if I remember correctly, so about 420bar) The tank flexes out with the pressure and when pressure is relieved the tank must return to within acceptable proximity of it's original volume. If it does not it is deemed not safe enough for use and removed from circulation.
@singful Aluminum :) In this video, they show one tank being made, but the machine that does the grinding may be making 50 at a time. I'd like to see the tanks anodized, but the natural crazing that may occur might appear to be cracks to a visual inspection.
@christian31121974 once all the processing equipment is paid for, after that its mostly profit. trust me the employees arent banking there...plus they make so many.....
The cost of the raw aluminium and the production process is actually the cheap part believe it or not, once the machinery is created that can knock these tanks out at a certain rate then the factory can make them until the cows come home. The expensive part of the tank is the shipping and commission taken by the shop or online retailer.
Its very interesting to see them test them. They use water for testing for the main reason if the vessel would rupture the compressed air/gass would be very dangerous and expand and cause a exposion. With water the breach just makes a poping sound and simply leaks out of the rupture with like no pressure behind it. The pressurising unit also shuts down quickly once it happens.

WoW! That was very cool! I have some aluminium tanks--unpainted--from the 60s that belonged to my dad. I wonder if they're still good. Some were filled as long ago as 1967--tags still on them--and never used. Is that bad? or is it good to help prevent corrosion? (Al doesn't corrode much but it does get a powdery surface oxidation.)
the tanks should be still good. how ever you should have them inspected and s dive shop. the main problem with AL is not "rust" [oxydation] but galvinis/ diss simler metal croution. IE where the tank and the valve meat.
the tanks are probably going to fail the vital hydro test or an inspection of the corroded tank valve threads. weigh the cost of testing against new tank purchase..........beheaded old tanks make a nice umbrella stand !
Well that's not always the case. I have a tank from 66 and it passed hydo and vis. Also if you didn't pay for it, then it might be worth the $40(or whatever they charge near you
.) If it passes then you don't need to spend several hundred $ on a new tank.
Technically the tank can still be put into use so long as it passed hydrostatic and visual testing. Unpainted eh? Somehow I doubt it'll pass..but it might.
However there is an issue with tanks prior to '89 that could be made out of an alloy that has seemingly randomly exploded despite passing regular testing.
@themightyharrison It actually does corrode and that white powder is the equivalent of rust on steel. Modern aluminum tanks are lined. Bring yours to a SCUBA shop to be inspected. No SCUBA shop will actually fill it unless it has a valid, up to date inspectrion sticker anyway.
@themightyharrison It is best to store the tanks with air in them. I would never use a tank that old. Remember SCUBA gear is life support. Spend the $200 bucks on a new tank. One from the 60's will have the wrong valve on top anyway.
That was really cool!

A brand new 80 cubic foot aluminum costs about USD$170.
andygray 2 years ago
this is an interesting process.
Can you hold more breathing gas with an aluminum or steel tank, given that both tanks are the same in volume?
soccom8341576 2 years ago
Ali tanks are usually limited to 207 bar, with steel they come in between 232 bar and 300 bar, so that a few more hundred litres of air.
unclepeter99 2 years ago
Usually it is steel. I have more details and a reference if you want to know.
Don't get me wrong, aluminum is a fantastic metal. Wonderfully light.
