Gas Bottle Date Stamps

admin

I went to exchange my 250 CF argon bottle today. I always check the dates just because. This is the earliest I have ever seen! Looks like it was made in 1910 and first tested in 1915 (Thanks for catching that Keith) Looks to be a swastika too. It's a Linde bottle from what I understand they were one of the first companies to start bottling gasses. German of course This has been one busy bottle! It didn't get stuck in someones garage for 30 years! The stories it could tell! Anybody else have some pics of old bottle date stamps?~Scott~You can see what projects I'm working on on my Facebook page.https://www.facebook.com/pages/Bucke...3595655?ref=hlbucket_of_bolts on Instagram HTP 221 DV
Reply:Just to clarify, it was tested in 1910 and that expired in 1915. Very cool to see one that old still holding pressure and doesn't have the swastika boxed in (just because it is more rare).GravelThe difference between theory and practice is that in theory there is no difference.
Reply:Actually I'm pretty sure that's just production date. How would they know when to retest it if it didn't have a initial date. Still it's about as old as you're going to see anymore since I believe they have a 99 year life. The next time it's hydro tested it'll be scrapped.    It's a year older than the oldest I have right now.Millermatic 252XMT 304'sDynasty 280DXHypertherm PowerMax 1250Miller Trailblazer 302 EFIOptima PulserXR feeder and XR Edge gun and more athttp://members.dslextreme.com/users/waynecook/index.htm
Reply:I once worked in a place that sold dry ice and CO2 circa 1978. Part of the job was filling 50 and 20 lb cylinders. I saw a lot of old early 1900 dates. If the latest date exceeded 5 years they were put aside to be sent out for testing.Some of the 50 lb tanks weighed over 110 lbs empty including the one I accidently knocked the valve clean off on a delivery! I picked it up about 150 yards down the street nosed into a snow pile still venting CO2 and the remaining contents at the base of the cylinder became dry ice.Sorry, every time I see tank dates I remember that place and the torpedo story.

Reply:The 99/100 yr rule is myth, they stay in service until they fail hydro and then if they pass at a lower pressure can go to CO2 service.

Reply:Not that it matters, but that is not the Nazi swastika. Nazi has reversed arms. The swastica was a religous and good luck symbol for centuries before it was corrupted by the Nazis. I have read somewhere, maybe in a thread on this forum, that the one on the tank was almost like a trademark or something. Anyway, nothin bad.To ride, shoot straight, and speak the truth. This was the ancient law of youth. Old times are past, old days are done, but the law runs true oh little son.Winpower 180 DCSA-200 redfaceXMT-304
Reply:Read this thread a few days ago and sure enough, the argon bottle for the Syncrowave looks almost identical to yours, a little newer though. It's also a Linde. This one has had the square stamped over the swastika to create the "window".

Reply:I got some confirmation the other day that they stamp the bottles with date of manufacture the other day. At least around here. This was a obviously new bottle that came in. It even still had one of the rubber bands on it.

Reply:Originally Posted by KelvinWhat puzzles the heck out of me is, what did they even use pressurized bottles of gas for, way back then? MIG and TIG didn't come along until at least the 1940s, I think...
Reply:I always thought the original manufacturer had to stamp the date and use a special stamp identifying them. I think a + stamp might indicate a 10 year certification too.

Reply:Originally Posted by GravelI just went and looked at 2 of my cylinders and you were right all along. I don't know WTH I was thinking. The one I bought new says 09 and the one I got tested last year says 14. I gotta quit smoking crack...
