FAQ: What is the difference between Pipe and Tube?

In short: Tube is measured by outside diameter, the pipe is measured by inside diameter. Keep in mind that pipe size refers to a nominal – not actual – inside pipe diameter. Schedule refers to the pipe’s wall thickness. When it comes to classification, pipes use schedule and nominal diameter, while tubes are classified by their outside diameter measurement and thickness.
