Always Protect Your Refrigerant Tubing, 2021-01-26

What is the difference between pipes and tubing? Many technicians commonly interchange the use of these terms; however, there is a technical difference between the two, and that is how they are sized. Pipes are sized based on their nominal pipe size (NPS), which is the approximate, but not exact, inside diameter. The inside diameter will vary based on the pipe’s wall thickness, which is known as its schedule. The outside diameter is held constant.
It is much easier to prevent containments from entering a system then to deal with removing them or the system failure they will cause.
