Polyethylene pipe is better able to structurally withstand an impact than PVC pipe, especially in cold weather installations when other pipes are more prone to cracks and breaks. Hazen Williams C Factor is 150 and doesn’t change over time. HDPE pipe has a smooth ID that does not corrode or tuberculate and maintains its flow capability over time.

Appendix A: Friction Losses for Water Flow Through Pipe

pipe. For PVC pipe, the standard C value is 150. New steel pipe uses a C value of 140, but with use and corrosion a lower value is typically used. For HDPE pipe, a range of C values between 150 and 160 is typical. Tables A.1 and A.2 show friction loss data calculated by the Hazen Williams formula for the most commonly used steel and PVC pipe

Mar 01, 2006· The table assumes all iron pipe starting at C=130 and after 100-years the C is reduced to a value between 29 and 59 (varying based on size). This table takes into account the fact that tuberculation will accumulate on the pipes (at a rate of about 3% per year) and reduce the effective inside diameter and reduce the amount of flow through the pipe.
