Reply:I would use black pipe, galvanized has a coating that can flake and damage air tools. Never had an issue with black pipe rusting thru in an inside application.Miller xmt304,  Miller S22 p12, Miier Maxstar SD, Miller 252 w 30A, Miller super32p12, Lincoln Ranger 9, Thermal Arc 181I with spoolgun, Hypertherm 10000 ,Smith torches.

Reply:Black Pipe. Keep the runs slightly pitched so water can run to a low point and be drained. That said I have a copper system only because I started with the copper about 30 years ago. No problems with the copper but probably expensive today.Ernie F.
Reply:I run black pipe also, if I started over I would run minimum 3/4 for the drops and bigger for the main feeds. But no complaints with 3/4 and 1/2 for most things. Have a drier and filters on the inlet and a couple down the system as well.ESAB Rebels 215 and 235, ESAB HELIARC 281i, ESAB ET 301i, Hypertherm 85 and 45XP, Thermal Arc 185, TD 60i, HTP PRO PULSE 300

Reply:I will post a picture in a few hours and the logic behind my set up.Thanks for the help
Reply:In our plant we run Schedule 80 CPVC for all our air.I was always under the impression to not use galvanized due to the potential of flaking.
Reply:Here is a few pictures. Each pipe is 4' long and the top pipe which runs to the right is 8' or 10'. The second picture has a separator an hose. I tilted the pipes (not level) to aid water to run to the bottom pipe which has a valve. Give me ideas of what need to change.

Reply:You might want to to look at the following before using CPVC for airlines.https://www.usplastic.com/knowledgeb...contentkey=787Mike
Reply:Summit racing sell a plastic air line. Money is tight. I may go that direction. My space is so small I need to max. every square inch. Additionally I want it to look profesional, as you can see in the pictures it looks rough. When people stop over to get stuff I don't want to look like a trash operation.

Reply:Last stuff I ran was pex but also have lots of copper in the finished areas and in some of the fab shops I also have several hundred feet of poly buried between buildings and another hundred as a main feed from one end of my sawmill building to the other end. I find the pex tough and simple to install, have seen summits pex/Al pipe... It looks nice but for the premium in price I can plumb three times as much shop in regular pex
