Steel tubing.

Unread postAuthor: Urban Ninja » Wed Apr 26, 2006 1:47 am

I am making a sniper gun out of galvanised steel tubing. I know that some copper tubes can handle up to about 300-400 psi but what about galvanised steel? Any ideas would be useful cos if it blows up its gonna kill.....

weakest parts are the threads,and the fitting will fly off in which ever direction they are aimed and also they are rated to around 6000 psi,so you should be fine.

I was wondering about some 3" exhaust pipe i have left over from my van, i'm sure it will handle any amount of presure my air compresser can put out. But it would be nice to know the numbers.

Galvanized steel in 1" can take ~2-3 thousand psi. I forget the exact number, but you get the idea - it's quite safe to put unregulated CO2 in it... infact, you can safely put CO2 in 2" steel pipe.

Though you may have a bit of trouble sealing the threads...

If it's filled up to 25 % liquid it should be fine if it warms up..
