Dimension stability: GRP piping system can maintain the required critical tolerances of the most demanding structural and piping application. The materials need the most stringent material stiffness and dimensional tolerance.
Strength to weight ratio: The GRP pipe has excellent strength to weight properties. When the ratio of strength per unit of weight is considered, GRP composites surpass iron, mild steel, HDPE (High-density polyethylene) and PVC (Poly Vinyl Chloride).
Very low friction factor: Value of 'C' in Hazen Williams equation for calculation head loss due to friction in pipes is 150-160 for GRP pipes against 120-130 for steel pipes. Thus, the low friction coefficient and the hydraulic characteristics of GRP pipes lead to significant saving in pumping costs.
Low maintenance cost: No maintenance cost due to absence of corrosion, zero replacement.
