Pipes The purpose with a pipe is the transport of a fluid like water, oil or similar, and the most import property is the capacity or the inside diameter.The inside diameters are close to 2" and the nominal diameter related to the inside diameter. Outside diameter are 2.375" for both schedules.Since the outside diameter of a single nominal pipe size is kept constant the inside diameter of a pipe will depend on the "schedule" or the thickness of the pipe. The schedule and the actual thickness of a pipe varies with the size of the pipe. Tubes The size of a tube is determined by it's OD and the thickness. The actual OD of a tube is just the same as it's nominal OD. A certain size of a tube will keep the same OD no mater what the thickness is. It is true for pipe except that the actual OD is larger than it's nominal OD. Pipe and tube is ever so simple. Pipes are used to transport something, and tubes to construct something; hence, tubes are defined by the od "outside diamater" and wt "wall thickness" (for construction stability), and pipes id inside diamater to allow a calculation for transportation viz., speed, volumes etc.
