Piping dimensions are different than tubing dimensions. Tube size is expressed as the outside diameter
[OD], for example 1.5" tube has an OD of exactly 1.5". Pipe size is specified by a nominal, not actual,
inside diameter. The wall thickness of pipe is described by the "schedule", such as schedule 40.
