air tank

Steve, yes, given that it is not rusty or anything.

Have a look at the markings on the cylinder.
You should see something along the lines of WP or MWP and some numbers this will tell you the maximum Working Pressure of the cylinder.

Steve,

For safety reasons, the gas bottles have a "use by" date for storing LPG. This is due to the potential for internal rusting of the cylinder due to gas in liquid form, from compromising the sound structure.

For the same reason as use for storing gas, I wouldn't attempt to store air in the cylinder before the bottle was retested and certified.
Now, bearing in mind the cost of doing this is about the same as buying a new bottle, logic tells me it would be much more practical to buy a purpose designed air cylinder in the first place.

But that's just me.

Test Pressure is 3.3 MPa (approx 478.5 psi).....
draw your own conclusions from that;-))

Once the valve is removed, it's easy to see if there's any corrosion inside...

FWIW, I'm using an expired 4.5 kg (approx 9 litres) cyl as an air reservoir on my C/T (it's what I had available at the time;-)), and have no issues whatever w/- storing up to 120 psi in it...

As for having it tested, how many home workshop compressors do you know about that are 30, 50, & more years old, & have never had the tank tested since new??...

I would have no hesitation doing what you propose (YMMV;-))

Regards, Ed C

thanks for the replies think i will make a tank out of it

I use one as an air tank putting in 130 psi. Main issue that I was warned of was to make sure you clean it well as: flammable vapour + compressed air = bomb.
cheers

K-Mart sell a 18Lt $30 air tank with fittings and most of all a pressure valve, if the pressure gets too high, I installed one in the Hilux

Thats the best link I can do.

In the auto section in K-Mart made buy arlec I think, only some stores carry them you may need to phone around 125psi valve.
