One of the primary determinants of the friction factor is the roughness of the inner surface of the pipe. Galvanized iron pipes often exhibit a relatively high level of roughness compared to other materials, such as PVC or copper. This rough surface can lead to increased turbulence in the fluid flow, resulting in a higher friction factor. Suppliers need to pay close attention to the manufacturing processes that can influence the surface finish of their pipes. Techniques such as improved galvanization methods or surface treatments could significantly reduce the internal roughness and thereby lower the friction factor.

3. Epoxy Paints Epoxy coatings provide an exceptionally hardy finish and are often recommended for industrial settings. They offer excellent adhesion, chemical resistance, and durability. However, it’s important to note that epoxy paints generally require higher preparation and curing times, which may not be suitable for every situation.
