    Default black pipe airlines and the crud that develops in them

    Black pipe airlines and the crud that develops in them.
    Seems aluminum piping the air compressor companies are offering is the way to go these days if you are building a new shop or thinking about redoing your airlines. The picture shows a line that was only a few years old. Granted the picture probably depicts a worse case scenario but the science is real. At least a 1/2" air hose strung along a shops' wall on an angle with a filter and water separator on the end won't develop rust and hold moisture. Copper corrodes, stainless has carbon in it that could react to acids over time.

    How long was that in service ? We demoed out a auto shop with 20 bays in it and at least one drop to hose reel minimum to each. Shop was in service over 20
    years and all pipe was in great shape. Actually brought some home and made gates for farmer.
    That may have been poor install. I never saw anything that bad. That looks more like a steam condensate return line inside.

    I believe the compressor website said a few years.

    You need to run with an air dryer in order to limit the internal corrosion on the air lines.

    I agree with you to a point, but it seems aluminum would have it's advantages over BP. Technology always advances, it never stays the same. I would use it over BP if I was redoing a shop's airlines or building a new one.

    I and all my friends use copper. My friend has had his wood shop on copper for 25+ with zero problems.

    I would imagine climate, shop conditions, hours of use and if moisture and water equipment was properly installed on the lines has a lot to do with it. I wouldn't have that much to put up so cost against copper or SS I don't think would be much of a factor. I like the way it connects, with some planning I could easily have mine up in couple hours.

    I don't need a lot of aluminum piping to do my shop, if I go 10 feet from the compressor make a drop and install a water separator, filter, valve and clean out I'm set ...so I do think cost would be a big concern.
