Which type of pipe is known to have the highest cfactors?

The selection of polyethylene (PE) pipe as having the highest c-factors is based on its smooth interior surface, which significantly reduces friction and promotes better flow characteristics compared to other types of pipes. The c-factor represents the coefficient of friction for a given type of pipe, indicating how much resistance the pipe exerts on the flow of water.

PE pipes are often utilized in water distribution systems due to their flexibility, resistance to corrosion, and ability to maintain a high c-factor over time. Their low roughness means that water can flow more freely, allowing for higher flow rates and efficiency in systems that require reliable water transport. This makes PE pipe an ideal choice in a variety of applications, especially where long-term performance and lower maintenance costs are desired.

In contrast, other pipe materials tend to have lower c-factors due to factors like surface roughness or the presence of corrosion over time, which can impede water flow and increase resistance. This significant difference in performance underscores the advantages of PE pipes in the context of water distribution systems.
