What to do with old oxy and acetylene bottles...?

[Derky]

BOC cold cut them when they dispose of them.

never realised until last week that that propane bottles are galvanised. suppose it's obvious really as you rarely see a rusty one

Acetylene cylinders should be transported upright if possible, if not they at least need leaving upright for a day when you get back to allow everything to settle again.
I didn't know that for years.

Neither did i, used to use them sometimes sitting horizontal in the pickup

Although to be fair, galv can wear off as much as paint

Stupid question maybe but could they be water cut? Would be interesting to see the thickness of acetylene cylinder!!!

Be careful if you want to cut and acetylene bottle open, they are not an empty steel tank. Do some research.



"Today, acetylene is shipped and stored in metal cylinders filled with agamassan, which is half-filled with dimethylformamide (DMF) or acetone. The acetylene is dissolved in the DMF or acetone. Such cylinders are safe to transport and use.

In Swedish, the porous filler is known as "AGA-massan", which would translate as "AGA mass", "AGA body", or "AGA compound". AGA was the company Dalén founded. The compound originally consisted of, among other things, asbestos, cement, and coal. The 1930 US patent also mentions kieselguhr (diatomaceous earth"

The acetone liquid can come out if you draw too much from the cylinder. We have a manifold system and had bother with it, what had happened was that sometimes only one cylinder had bern opened to run the manifold and therefore drawing too much. It partially blocked the mesh filters on the hoses. Was black in colour.

Yeah its 1/7 of the cylinder per hour max take-off
