the dangers of dwv

[mopherman]

I'd never make a pvc gun unless it was pressure rated. theres a dwv fitting called a bell reducer. instead of using that you use a bushing? if there was no rating why would people use the bushing?

that is PVC is it not? not even i am stupid enough to use that

As most of us saw in a topic a couple of months ago, ABS also shattered. It was cellular core, which is the same as what you probably used. And anyway, I would much rather use DWV PVC than ABS, because I know DWV PVC can at least hold some pressure.

Cork the fittings i'm sure are rated to 300 psi up unles they are dwv.

look . i am tired of you telling me that abs can not hold pressure, because i have hade a piece of abs pipe at 120 psi for half an hour and it is in one piece. they pressurize that pvc pipe for 5 seconds and booom , pipe all gone. and if you call that video holding " some " pressure, i call that blowing up with "little " pressure. so if you got a problem on how i make stuff go cry to ya momma or something. this is a web site for ideas and people to show off their cannons not for you to tell people lies about ABS pipe. sorry for anyone else readong this, but i am just a little mad right now.

nfs-pw is desined for pressure well with liquids but they say thats beacause with gases if it explodes shrapnel gose everywere with water it dosent.

[pyromaniac]

Super spudder on my pvc it says 300 psi max. i call that pressure rated

[cork9]

on the pipe or the fittings?

[Bubba05]

ABS is used in irragation systems and can handle some water pressuse but not that much coz it ruptures.

[cork9]

yea really supper spuder stop saying domb shit

[Bubba05]

Yeah I got 300 psi max on my pipe to mate but im not going to put that much pressuse on it coz its plastic! that stuff is gas line pipe and is great for cannons.
