Does the thermoplastic liner provide less fluid friction than steel?
Yes. Not only is the fluid friction less on new product, but the thermoplastic liner also retains this lower friction throughout its operating life. Fiberspar recommends using a ‘C’ factor of 150 in the Hazen-Williams formula for friction loss. In higher flow regimes, the smooth internal surface of Fiberspar pipe and the minimal use of connectors also reduces turbulence.
