copper and iron

[saladtossser]

what are copper pipes and iron pipes/galvinized steel pipes rated to?

[spudshot]

taht depends largly on what size and wall thickness you're looking at, copper is rated to about 500 psi, thats M type thats 1" diameter, i used that in my piston cannon, otherwise i dont know off the top of my head

metal pipes r usually quite a bit stronger then pvc, not always but usually it is so it can go to higher psi
