Others 180 Bar Aluminum Tanks Question

[Jaabaa]

We used these Tanks for testing dangerous gasses with our meters when we worked underground on the Telco lines. I do believe these are good for CO2 but was hoping someone was familiar with them.
Been trying to post these pictures for a couple days and the system or my phone would not let me.
Thank you

All the markings should tell you all you need to know. Mfg date, initial test date, test pressure, working pressure.

You may want to have them tested before you use them.

I don't believe there are any specific restrictions on type of gas with aluminum cylinders unless it is corrosive.

Thread gauge is where it falls apart with industrial bottles. If it is non standard or custom then you probably won't be able to use them. I couldn't read the thread gauge.

Thank you, I am to take them to the scuba shop next week. He said they may be trade-in good.
I can get more if that's the case. Thank you

Wow, that would be excellent. Never heard of them taking in trade.
