[AT] Air lines for shop

[Easley, Greg A.]

I used PEX in my shop.  Installed 2007.  Zero issues since.

So I'm going to be making three new pipe runs from my air compressor.  Previously I've just relied on hoses since the 50 foot hose will reach everywhere in my shop.

It will consist of one long "trunk" run that will be nearly 40 feet, and then a few stub runs of anywhere from 5' to 15'

I was thinking about black pipe as that's what I have used before. But I had no idea the common, affordable black pipe you find in hardware stores is only good to 150 psi. My compressor is two stage and is 175 psi:

I guess I'm thinking about biting the bullet and going copper. I'd like to go with some of those really neat new aluminum systems but I could never afford that.

What are y'all think about copper? I know 3/4" copper is good to about 1000 psi.   It eliminates  the rust problem that eventually befalls all black steel pipe systems; which is kind of a plus.  As far as installation, I solder better than I cut threads :-)
