<div>Something tweaked my memory from plumbing the Huber about
different pressure ratings for steam, air, and fluids with
schedule 40 and 80 pipe. The 150 psi may be the steam rating
and the air rating is 34 to 6 times higher.</div>

<div>Go copper if you're comfortable with sweating it
together. I did that after trying PVC for awhile. Got some
AZ sun on the PVC and it blew out a couple times with
sharp little shards flying around (doesn't survive impact
damage well). I like the sound of PEX but again, sunlight
is abundant here. <br>

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.<br>
<br>
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’ <br>
<br>
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:<br>

<br>
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.<br>
<br>
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 :-)<br>
