If you do decide to go with black pipe, you can measure what you need and get it cut and threaded at Lowes or HD. Place a flex hose between the compressor and black pipe to prevent vibration problems. Having it run down hill will help the condensation get to the last fitting to drain the line. Mine was at about 48" AFF with outlets every 6'. Better to have too many than not enough. Harbor Freight has a good hose reel as well to add to the system.
