[TowerTalk] tubing vs pipe

[Bert Almemo]

This is the first time I've heard anything to be defined the way you measure
it!! The difference between pipe and tube is how it's made - not how you
measure it or what you use it for.

Pipe is made of cast iron or other metal and tube is made of sheet metal
that's folded and welded or drawn from a blank through a die, cold or hot.

Correction:

Pipe is also measured outside.  For example, all so-called "2 inch" (Iron
Pipe Size) pipe is 2 3/8 inch O.D., regardless of wall thickness.  The I.D.
varies from below 2 inches to above 2 inches, depending on wall thickness.
It also varies depending on the material the pipe is made out of.
