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.

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.

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.

Back where it all begins

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.

I’m going to have to watch this again when I’m not so tired so I understand hyrdostatic testing.

Great video. I always wondered how they made tanks. Now I can wonder no more. Thanks

The coolest part was stamping on the info around the tank. Really neat apparatus; simple, cheap, effective.
