Pipe is customarily identified by “Nominal Pipe Size” (NPS), with wall thickness defined by “Schedule number” (SCH). Tube is customarily specified by its outside diameter (O.D.) and wall thickness (WT), expressed either in Birmingham wire gage (BWG) or in thousandths of an inch.
Pipe: NPS 1/2-SCH 40 is even to outside diameter 21,3 mm with a wall thickness of 2,77 mm.
Tube: 1/2″ x 1,5 is even to outside diameter 12,7 mm with a wall thickness of 1,5 mm.
