What is the Difference Between Pipe and Tube?

08-000-002

  Tube
Tube refers to round, square, rectangular or any shape of hollow material that is defined by the O.D. (outside diameter) and the wall thickness. For example, an appropriate description to specify a tube size would be, "I would like a 1-1/2 inch O.D. tube elbow with a 1/8 inch wall thickness."

To order tube handrail components:
Specify O.D. (outside diameter)
Specify wall thickness
 
  bulletPipe (most common)
Pipe is round material that is defined by specific O.D. (outside diameter) and I.D. (inside diameter) measurements and the pipe schedule thickness. For example, an appropriate description to specify a pipe size would be, "I would like a 1-1/4 inch schedule 40 pipe elbow." It is important to understanding that a 1-1/4 inch pipe does not have an 1-1/4 inch I.D.; rather, it has a 1.38 inch I.D. based on a schedule 40 thickness.

To order pipe handrail components:
Specify the pipe size
specify the schedule thickness (40, 10, or 5)
or,

If you don't know the pipe size you can:
Specify O.D. (outside diameter)
Specify I.D. (inside diameter)
Specify schedule thickness (40, 10, or 5)
