The relative roughness of a pipe is its roughness divided by its internal diameter or e/D, and this value is used in the calculation of the pipe friction factor, which is then used in the Darcy-Weisbach equation to calculate the friction loss in a pipe for a flowing fluid.Pipe Roughness - Pipe Flow Software

What is the PSI of a PE pipe?What is the PSI of a PE pipe?There are additional restrictions imposed by this Code, such as the maximum pressure at which a PE pipe may be operated (which at the time of this writing is 125 psi for pipe 12-in and smaller and 100 psi for pipe larger than 12-in through 24-in.) and the acceptable range of operating temperatures.Chapter 6 - Design of PE Piping Systems - Plastics Pipe Institute(HD-3) (HD-4) (HD-5)

Later, after the PE pipe has been installed inside the steel pipe, a compression ring made of the same CRA material would be inserted to press the PE pipe into the ridges. This would form a permanent connection between the PE pipe and the carbon steel pipe.

Aug 04, 2008The PE Handbook says "Pipes that have absolute roughness equal to or less than 0.00001inch are considered to exhibit "smooth pipe" characteristics." This is nonsense (although I do have a high regard for the PE Handbook as a whole.)
