Here's where some dispute what to use. Steel will work but will rust on inside. Air condenses and water is created. Water will eventually settle in your pipes. If you use regular blk pipe I suggest a really nice air filter and dryer bc if you don't you may see rust coating on things you blow on to. There is galvanized pipe but it too corrodes or oxidizes. Mix that with water and you may see a white residue on things you blow on. Again, I'd use a really good filter dryer setup. Casey835 used polyethylene flexible pipe with SS quick connects. He has a Devilbiss air filter and does well with his sandblaster. Maybe he will chime in. I went with copper pipe bc I'm fairly good at sweating. Plus I has a lot of joints and connectors. All I had to buy was 50' of pipe. A cheaper soln is PVC pipe. I've seen lots use 3/4" pipe bc its easy to cut and glue. PVC isn't designed to hold 125lbs of pressure,but if you keep it at 90-100 you may be good. Your typical house only can handle 80lbs of water pressure till it starts blowing seals in faucets.

Regardless what pipe or tube you use, it's about the layout. You need that moisture inside your pipe to collect at a point or two. That's where a relief valve is needed. Do a search and you will see all diff designs. Another good thing to have is a good filter/ dryer. You will appreciate a good one when you start sandblasting or better yet painting. Fish Eyes in paint are caused by water droplets and or oil in the line. I have two water filters going to a hose reel. It does well for my use. My other outlet is set up for a nice air filter and dryer, should be ordering it this week. It will run the blasting cabinet and any painting that I choose.
