Hi All, I'm new to all this, so excuse me if this has been covered already. I was at Lowes today measuring gas pipe for the rails. I quickly realized the 1" pipe doesn't mean O.D. This explains it. Surprised me it was so far off. Might help someone else. http://www.ajfittings.com/performance_charts.htm Dave  |

Pipes are measured by the Inside Diameter I.D., versus tubing which is measured by the Outside Diameter O.D. Pipes are used to move fluids, it's important that all pipes of the same size have the same inside dimension (turbulence and lots of other problems). Tubing is used for construction, keeping O.D. constant is important! |
