I spotted a vintage oxygen bottle in the rack today. US army air corp. put into service in 1945.

As far as I know nothing has changed. It’s amazing how long high pressure cylinders last. I’ve seen initial hydro dates from the 30’s
Yeah i have a couple that old. They are cool. Not trading them in, just fill
Yeah... because Greta says we don't recycle enough.
Build things to last and we don't have to have all the ghey recycling shit. We just keep using it forever.
Sirhr
I worked a industrial gas supplier. We would keep an eye out for older German tanks to modify the stampings on it when testing.
It is amazing how long these things have been in service.
There are not my photos.

At the refinery I just retired from (shell) we have a charge pump on the Coker that has a swastika embossed on the case. Been running pretty much nonstop since 1940.
Linde tank? Those are the most common from what I remember seeing.
Super yep, I'm glad I read the thread through some before replying.
Great reply w great pictures.
And, I don't remember for sure, but I think the first compressed air bottles were linde, german, WW2 hits, you have swazticas on bottles.
When I welded for a living, I saw the closed in sawz alot. Alot alot, those bottles are the shit.
I believe it was a Linde.
At Goodyear we dug a pit about 10 feet below the elevator shafts.
Then used a Cat 375 with a LaBounty shear on it and we'd cut the CO2 tanks down in the pit.
I've seen one ton cylinders with in-service dates as old as 1916. 150 pounders from before WWII. We use a lot of N2 at my current job, probably 50% of the cylinders are Army Air Corps or pre-war era and still perfectly fine, change the valve occasionally.
On an odd side note; If you are looking for a cylinder to make a bell out of pre-WWII cylinders come out best. I used a 1930's USN CO2 fire bottle for a garden gong for my wife, it sounds amazing and holds a ring for over a minute. The walls are thicker back in the day and the cylinder was higher quality steel. It is easy to see why they last decades after you cut one open, older ones are up to twice as beefy as newer ones.
