Old Oxy Act cylinders

[Josey]

Hi. I have this old. must be antique set of old B0C. cylinders sitting in my shed.
I brought them from the UK over twenty years ago. and never could get them filled
or exchanged here in Manitoba. Any suggestions what to do with them? other than
scrapping them. Thanks.

They make great wind chimes or bells,,
I cut a 300CF oxygen bottle with a 9X16 saw, and hung both halves.

The wind chimes sell for BIG $$$ in the right market.

There are lots of YouTube videos,,,

Check out the “Scrap metal art and projects “ thread right here on WW.

Maybe a rocket great to sell to to teenagers with match.

Old doesn't matter as long as it still tests well.
There are pics on the internet of bottles with World War 1 dates and military proof marks still in service.


I've seen those wind chime bells.
I hate the extra noise, no need for it.
Nothing wrong with silence.



They make great compressed air tanks, super high ratings thousands of PSI, lots of safety factor.


Pull out the valve, it's restrictive.
Maybe 1/8" orifice inside

Put normal 3/4" pipe fittings in it.

Parallel them together, mounted upside down with an auto drain on it.

I had one too. The guys here turned me onto "stumps" so I made it into one.

I don't know about most acetylene tanks - but mine had highly compacted asbestos in it. Couldn't imagine what it would have taken to clear it out. I cut it flush and welded a plate over it to mount wheels.

For the OP, get the cylinders tested. Unless they're rusted or damaged cylinders can be in service indefinitely.

Acetylene cylinders don't have asbestos. It could have been pretty dangerous cutting and welding on an acetylene cylinder. Below is short blurb on acetylene cylinders.

Acetylene cylinders differ from other compressed cylinders in that they contain a porous
filler material (or mass), and a solvent in which the acetylene is dissolved.
If acetylene were to be stored as a compressed gas in cylinders (in the same way as other
gases) it would be very unstable and could decompose explosively. For this reason, it is
dissolved in a solvent, which allows greater quantities of the gas to be stored at a lower
pressure in a safe manner.

Cylinders from UK may not possess the proper approval stamps needed and may not be able to be certified for that reason.

We one supplier that purchased tanks made in late 1930's from Germany they tested good just put blinders on for stamp used by Germany Army.
One group would not buy from that company. It was strange to see that stamp in America.

Just sharing what I read...

I cut it with a bandsaw after it wouldn't fill with any water at all. I cut the protruding material with a Sawzall, threw it in the fire pit, and tried to light it off. Smoldered for a minute, then kept going out.

When welding, the worst was the acetone kept contaminating the mig beads.

As Shootr mentioned, one of the handiest tools in the shop is the metal stump. They're great for shaping sheet metal, and I've used mine to make dishes from .125" flat as well as turn rings in 1x1/4" bar.

Just fill it up with all kinds of extra mass if you can to deaden the ring and keep them from bouncing around. Sand works really great if you add a bit of oil to prevent corrosion on the inside.

Yup, seen a few of those cylinders locally. They had a square stamp with a cross inside the square... All marked "Linde" from Germany.

Stick a magnet or two on the sides of the cylinder to take all the ring out. Same with a bad ringing anvil.

If you have acetone coming out, you could have big problems because there would be unstable acetylene that could explode. If the cylinder was really old and not filled for decades it could have some asbestos in it.

With the millions of cylinders out there, I'd bet there are a lot that go from country to country and have to meet pretty common standards. The UK isn't a 3rd world country where anything goes. What's interesting is I saw a video years ago from BOC in the UK where they lay the cylinders down and kick them to move them. They can roll several at a time using this technique but then have to stand them up. It was odd to see them rolled on the ground like this.

FACTS AND DIFFERENCES ABOUT UN/ISO AND DOT/TC STAMPING REQUIREMENTS

1. Gas fillers in the USA can legally fill UN/ISO or DOT cylinders that meet CFR regulations.
2. Both All Safe UN/ISO and DOT cylinders are manufactured in the USA and other Foreign countries.
3. Both DOT and UN/ISO cylinders have the same dimensions, internal water volume, steel chemistry, and valve
compatibility.
4. ISO cylinders are tested to, and have a higher working pressure and gas volume capability than DOT/TC cylinders.
5. DOT-stamped cylinders are acceptable for transport to, from, and within the United States. UN/ISO-stamped
cylinders must have "USA" country of approval marking to be acceptable for transport to, from or within the United
States. All Safe’s UN/ISO cylinders are stamped “USA”.
6. DOT markings must conform to applicable requirements of 49 CFR 178.35. UN/ISO pressure receptacle markings
must conform to applicable requirements of 49CFR 178.71.
7. DOT and All Safe UN/ISO cylinder markings are expressed in conventional units.
8. DOT and TC date of manufacture is month-year (10-13) while UN/ISO is year and month ( 2013/10) 9. DOT stamps service pressure only in psi. All Safe UN/ISO cylinders have stamps for Service Pressure (PW) and
Test Pressure (PH) in metric (BAR) and PSI.
10. UN/ISO requires inlet thread to stamped. DOT does not.
11. Manufacture approval number granted by U.S. Department of Transportation (Pipeline and Hazardous Materials
Safety Administration) for both the DOT and UN/ISO. If manufactured in same facility, the approval number will
be the same.
12. Third-party independent inspection is required for both DOT and UN/ISO designs.
13. There is no plus or star for UN/ISO cylinders. The service pressure is already at or above the 10% over-fill
authorized for select gas services by DOT.

[Welder Dave]

That's very interesting and informative. I've never had to inspect cylinders or looked a lot of them over to see if they were DOT or UN/ISO. I would suspect most cylinders, especially the larger ones, would meet the higher specs. of UN/ISO. Would be interesting to know if there are a lot of DOT only cylinders out there in 244 size which is the most common.

Stick a magnet or two on the sides...

Magnets will help attenuate the sound, but they don't add to the mass. Backfilling the cylinder with sand and oil kills the noise and makes the stump far more useful because it isn't wobbling around. Two birds, one stone. Plus it's a good way to use up all the little scrap from your saw and lathe. When I made mine, I hunted all over the shop for any swarf, scale, rusty nails and anything else I could find. Then I topped it all off with sand and oil. The finished stump is properly heavy, won't rust out from the inside, and works wonderfully because of the added weight.

Bowling ball mortars are a popular use for old high pressure cylinders but probably illegal outside the US.
