Although
pipe comes in different wall thicknesses, the outer diameter
is kept constant in order to screw into pipe fittings.
Pipe is designated by nominal ID and schedule.
Nominal ID is nominal inside diameter. Typical
schedules are 40 (standard wall), 80 (heavy wall), and 160
(extra heavy wall).
Tubing may be made by welding (has
an internal seam) or by extrusion (has no seam).
Square tubing is actually a subset of rectangular tubing.
