Being fabricated on unsaturated polyester resin, GRP pipe is to provide effective and stable water supply by superior leak tightness against subsoil variations result from earthquake or settlement of poor ground. It comprises sand to enhance stiffness and high elastic glass fiber to improve performance against internal pressure.
Major Feature of Process
High Stiffness/High Elasticity
- More than 30 proven experiences on wastewater treatment plants over the world
- Proven technology by many operators CSBRTM Project experience internationally
Constructability
- Minimum operators by automatic operation
- Maintenance & repair of all diffusers without emptying tankage by use of retrievable equipment systems
- No interrupted continuous flow using novel fixed type decanters
Stability/Maintenance Ability
- The linear expansion coefficient (n=0.010) is superior to the other pipes with slippery interior surface like glass. Thus the GRP pipe can convey more amount of water economically.
- Specifically-structured EPDM(Elastomer) coupling used for pipe joint shows excellent tightness. It shows excellent leak-free characteristics under adverse conditions such as unsettled subsurface or ground settlement.
- GRP pipe is less dependent to temperature than other materials (Cast Iron, Steel, HDPE etc.)
