Difference Between Pipe and Tube

The main difference between a pipe and a tube lies in their shape, size, and usage. A pipe is typically a cylindrical, hollow object used for transporting fluids or gases. It is defined by its nominal diameter, which refers to the internal diameter, and is measured in standard sizes such as inches or millimeters. On the other hand, a tube is generally more rigid and is defined by its exact dimensions, including both the outer diameter and wall thickness. Tubes are often used in applications where precise dimensions, such as structural support, are critical, whereas pipes are more commonly used for fluid and gas transfer.
