What is the difference between Pipe and Tube ?
People use the words pipe and tube interchangeably, and they think that both are the
same. However, there are significant differences between pipe and tube.
The short answer is: A PIPE is a round tubular to distribute fluids and gases,
designated by a nominal pipe size (NPS or DN) that represents a rough indication of the
pipe conveyance capacity; a TUBE is a round, rectangular, squared or oval hollow section
measured by outside diameter (OD) and wall thickness (WT), expressed in inches or
millimeters.
