anyone have any idea where to find 5 feet of 2 inch copper pipe, the only place ive seen it is on my houses drainage system which is 40 years old, now they just use pvc. home depot, ace, etc. only carry like up to an 1 inch copper pipe?

also just curious, i plan to use my cannon for paintball at 100 psi-125psi but what are some nice target pressures that the copper can hold aside from the vavle

Yeah, they have it at my Lowe's too. Copper can be pressurized pretty high, I believe to around 500 psi. I'm kinda confused, are you using 2" copper pipe in a paintball cannon? That'd be pretty heavy.

Heres a guide to copper pressures I dug up for the UKSGC reference section: http://www.indanc.com/tubing_62.php

If you want to live on the edge you can take into account that the BURST pressure (the one you REALLY don't want to exceed) is a LOT higher.

At school they were doing maintenance and I saw them installing what looked like 2.5" or 3" copper pipe into the wall, it was damn beautiful.
I hated to see it be used in such a non-destructable way

my concern for paintball is i need a metal chamber to handle impacts such as falling and cold temps and paintball hits etc. Originally i was gonna use a small size copper pipe, but the barrel needs to b 1.5 - 2 inch pipe, so i jsut figured make the chamber that size too so it looks good and has the air volume.

That going to weigh a ton, so while being nearly indestructible you will be highly bogged down. And what kind of valve were you planning on using? The stress on it will be quite a lot, with the chamber and barrel made of heavy steel.
