One of the most frequent questions we get from customers is “What’s the difference between pipe and tube”? Althoughpipesandtubesmay look similar, they are in fact quite different in nomenclature and sizing. Remember that pipes and tubes are rarely interchangeable. Here are some of the main differences between the two products:
Pipes are always round in shape. Tubes can besquare,rectangularorround, as shown in the image to the right.
Tube is stronger than pipe.
Tube is available in hot rolled steel and cold rolled steel. Pipe is typically black steel (hot rolled). Both items can be galvanized.
Althoughcopperandbrass tubescan be shaped relatively easily, tubes are are typically rigid. Pipes, on the other hand, are invariably rigid and cannot be shaped without special equipment.
Pipe is typically available in larger sizes than tube.
