Copper Tube - Round

All copper tube is hard drawn UNS C12200. 

What's the difference between pipe and tube?  

The way it’s measured and the applications it’s being used for.

Pipes are passageways. Tubes are structural. 

A pipe is generally measured by inside diameter or ID.(IE: You could roll a 2" golf ball through a 2" NOM pipe.) Tube, on the other hand, is measured by Outside Diameter. (So your golf ball would have the same O.D. as the 2" tube.)
