Why Choose GRP (FRP) Pipes & Fittings?
1. Corrosion Resistance
With Pipes & Fittings, forget about frequent maintenance. These pipes need no coating, gunning, mortar lining, or cathodic protection — ideal for aggressive and corrosive environments.
2. Superior Strength-to-Weight Ratio
Compared to traditional materials like steel, cast iron, or Pipes & Fittings provide greater strength while being lightweight, helping reduce operational costs in transportation and installation.
3. Lightweight Advantage
At only 1/5th the weight of steel and 1/10th of PSC, GRP (FRP) offer easier handling, faster installation, and logistical advantages, especially in challenging terrains.
4. Smooth Internal Surface
The internal surface of GRP (FRP) Pipes & Fittings is extremely smooth, offering significant advantages:
- Hazen-Williams Coefficient: C-150
- Manning’s n: 0.01
This results in superior hydraulic performance, reduced pumping costs, and improved energy efficiency.
5. Long Continuous Lengths
GRP (FRP) Pipes & Fittings are available in longer lengths, reducing the number of joints and significantly lowering the risks of leakage and installation costs.
6. Leak-Proof Jointing Systems
Designed with advanced jointing technology, GRP (FRP) Pipes & Fittings prevent both exfiltration and infiltration, delivering a long-term maintenance-free pipeline.
