Fiberglass Reinforced Plastic Pipe - Composites USA

Fiberglass pipe has a smoother internal surface than steel pipe, with a Hazen-Williams roughness coefficient of 160 when new, or 150 used. Steel pipe, on the other hand, has a Hazen-Williams roughness coefficient of 120 when new, or 65 used. The far greater loss in smoothness for the steel pipe is due to scale build-up on the steel pipe.
