http://www.spudfiles.com/forums/viewtop ... &lighter=& i used steel for the barrel in my gun, mostly because i wanted to weld the bolt on, so the bolt action would work. i think in the long run the steel pipe would rust a bit too.

Why not steel?

First off its overkill for our usage, although its used when the expectations of the cannon increase/ call for it. Secondly, its cheaper to puy PVC. Though ive heard its quite hard to buy/find PVC in any suitable form in other countrys. Thirdly, construction in easier. With any metal you have to weld the joints or thread them. Now I think most of us without welders (good ones at least) would rather spend at most $5 dollars on a can of glue to "weld" PVC rather then 200$+ for a welder. Threads can leak so basically doing so can defeat your original intent.

careful, galvinized steel can give off zinc gas when welded, do so outdoors if you must

Cost comparison
1 foot of 1/2 inch Sch 40

PVC $0.32
Steel(threaded) $1.50
Brass(threaded) $14
Aluminium (Unthreaded) $10
Stainless (Threaded) $21

As you can see pvc is cheaper by a massive margin

@spudshot:

there are big difference between brittleness and pressure overcoming.......as cast iron can withstand much bigger pressures than PVC,although it is brittle.....so i need to know by means of standards what is the Pmax that CI could bear?....or any one don't know?
