Thermal Expansion & Contraction of Pipes

Coefficient for Expansion is a Top Priority
Each material (steel, copper, PE, PVC, etc.) has its own specific coefficient for expansion. These coefficients determine how the various materials react to differences in temperature. Steel has an expansion coefficient of 0.012 mm/C° and PE an expansion coefficient of 0.200 mm/C°. In other words: a 30 foot steel pipe set with a temperature difference of 120 F° expands 0.25 inches. A PE pipe of 30 feet expands .5 inches The expansion or shrinkage is not dependent on the diameter of the tube, but on the length and the material of the tube.

Great Video for all who work with "Tubing & Piping" technology. This is a good introduction for any professional in the welding profession. Thanks for the excellent graphics. T J (Tom) Vanderloop, Author Technology-Instructor & Mechanical Design/Fabrication Consultant

Excellent. Someone should show this to Elon Musk and co when they talk of the Hyperloop.

Lol I just searched for this video so I could link it in the comment section of a hyperloop video.
