What type of air hard lines are you guys running in your shop. Soon enough it will be time to put air lines in the new shop and i want to know what you guys like. I've done the cpvc route before, but i didn't really trust them cause they could get snapped off pretty easy and turn into shrapnel. At my old work we used iron pipe, which is ok but it gets a bit expensive for allot of it. My current workplace uses a combo of iron and copper pipe. Copper can get expensive too but i think this might be the best route. What are you opinions?

use copper

Ya that's the way i'm leaning i'm just curious if anyone knows of any other good ways. Something i don't know about. Like the cpvc was a good idea i didn't think would work. It was quick and cheap, i just wasn't sure what would happen to it if something fell and hit it while it was under preasure.

I was just in a newer shop the other day and they had plastic lines. Similar to water lines. Didn't really like it though. Some just use sched40 pipe.

Kronic

All of our lines are copper , no problems to speak of......well ya there is LOL , before ya crack the main shut off valve for the compressor make sure all the solder joints are cool , ask me how I know , HahahahaHarhar Haha.....blows freakin solder all over yer tool box and the air chuck turns into a freakin bullet , not funny.

I did one out of cpvc one time. Worked great, was much cheaper then copper, but i was always afraid of something hitting it and it shattering. Something about plastic shrapnel that did sound appealing.

Yep in the shop we ran copper for all the air lines, and along the benches we put a chuck every 10ft on the front.
