PVC pipe for garage air

I read an article in Stree Rodder on using PVC pipe for plumbing your garage for air.  I know that it is a lot easier to run and the fittings are a whole lot easier to install and make leak free, but after a period of time PVC pipe deteriorates and under pressure it will explode sending out small razor sharpe pieces!! I did some research a while back and no manufacture would tell me that PVC was good for pressurized air, if I remember correctly it had to do with UV rays.  

I don't know if it would work with  120psi. Also I have a tendency to stress my air lines and black pipe can handle both. Just be sure to drain *** at the low points.  

what wound be the next choice, copper or black pipe? to cut & rethread pipe might be time consuming & you would need a pipe cutter & die set, or 1/2" copper? just cut & solder? anyone out there got some suggestions?  

PVC is NOT intended for use with air. I saw a 6" line test with air that blow up. Lucky no one on site or their would have been deaths. Screw pipe or copper. Copper is costly. You only need to get close enough for your hose.  

MOST I'VE SEEN ARE STEEL PIPE LIKE ONES USED FOR NATURAL GAS LINES. EASTWOOD COMPANY HAS A COMPLETE KIT TO OUTFIT A TWO CAR GARAGE IN THEIR CATALOG OR AT EASTWOOD.COM  

i run 3/4 pvc pipe i,y shop. i keep my air pressure at 120 lbs.and i have never had a problem. i use schedule 40 and i think it has ia 600lb pressure rating.on all 4 walls the pipe is slightly angled and we have drains in the runs so we can drain water out of the lines.ours has been in use for 5yrs, my buddys shop has the same thing and his is going on 13 yrs.pvc pipe will not deteriorate for many, many years if it aint out in the sun.but it will freeze and crack if you dont keep it drained.and you will need a good water trap because of heavy condisation in the summer.i even use it in our paint booth.make sure you use good pvc primer and glue and push those fittings all the way on.  

1" schedule 80 pvc is good for 720 psi. I would NOT use anything less than shedule 80 just for the safety issue, and I would thread it rather than use glue fittings.

personally I used copper, it doesnt corrode and you dont have to worry about it breaking. I wouldnt advise black pipe due to the corrosion issues, unless you have filters at the outlets.  

I did my garage in galvanized 3/4" pipe. I went that route rather than deal with the rust from black pipe. And yes I do drain the system regularly and have a good Devilbiss filter.
