  • Air lines

    I am going to install hard air lines in my shop. I have decided to go copper or iron pipe. If I use copper can I use Type M?

    Re: Air lines

    Thats fine. Many folks go pvc. Many nay sayers on this. Never heard of a problem ,Myself.
    schedule 80 would be very strong. Use a water seperator. I , myself would be conserened
    with freezing conditions and pvs and possible water in lines
    I can build anything You want , if you draw a picture of it , on the back of a big enough check .

        I like steel in a shop. It is very strong, dent and bash proof and easy to modify if you have to. copper is ok, plastic is a no no.

          Copper is the best choice (no worries from rust), steel next.
          Plastic is a definite NO! Unsafe.

              Black iron with water traps on your drops will work great

                I concur. Copper is OK too though.

                  I would use galvanized for your air lines, and leave drain downs for the condensation.

                  Galv has proven itself with gas and water here.

                  I would not use black pipe

                  Galv all the way, and it costs less then copper. The only thing, you need a way to thread it

                      I've run air lines in Sch. 120 plastic, we threaded it and used threaded fittings, but it was in a chemical plant with a very corrosive environment. We had to get a waiver from OSHA to install it.
