In this thread you can write about preassurerated tanks like PVC-pipe,oxygen-tanks,compressortanks.Almost all tanks that you can put air in!

Okey,my tanks that i used for my cannons is from my dad that work as a firefighter and he get two steel-tanks for me that are rated to 17400 PSI(1200 bar)

good idea ,i think
i have fire extinguisher ,it's gauge max 35-40bar,but label wrote water pressure test in 21 bar
Do you think it s safe with 20 ,maybe 25 bar?

What about those copper ones with one end sealed.off. That they sell at the hardware store

you can use some galvanized fittings and pipe, they work great, and are pretty safe to take it past 500psi easily.

you can also use soda stream bottles if your really want to, i think you can take them up to around 800psi or something like that?

soda stream bottles are used at 200 bar... At least here in europe.

I think a distinction should be made between the plastic soda stream bottle and the refill cartridge, otherwise consequences of a misunderstanding could be interesting

I meant the metal ones with a co2 pin valve on it

I used to be a spudder like you. But I took a soda stream to the knee.

No there used at 800 psi like most co2 applications, i have personally put 100 Bar into one of them (1500psi) , i think there safe to about 2000 psi

The soda stream co2 bottle that are sold here has 200bar printed on it, rather safe pressure rating or charged co2 pressure probably pressure rating as co2 liquidates at around 1000psi.
