Piping and Tubing

A complete refrigeration unit is composed of several parts that function to vaporize and condense the refigerant as it circulates through the system. Refrigerator parts are placed at a distance far from each other so it is necessary to have a good piping system to have the refrigerant travel. This is made possible with the use of piping that is only a hollow bar to transfer liquids and vapors from one part of the system to another.
Piping is ordinarily understood to have walls of considerable thickness, while tubing has comparatively thin walls.
