Nominal Dimension of a Pipe
Pipe sizes are sometimes described by their nominal dimension rather than their true outside diameter. For example, a 1-1/2" Schedule 40 pipe size actually has an outside diameter of 1.900 inches not 1.500 inches. The table below cross-references the nominal dimension of a pipe with its actual outside diameter. Note that a Gatorshield tube with an outside diameter equal to or smaller than the Schedule 40 pipe can have a thinner wall and still be as strong or even stronger than the corresponding schedule pipe size.
