GRP Pipes
Introduction
Glass Reinforced Plastic (GRP) pipes are manufactured using the process of Continuance Filament Winding (CFW). Our range of GRP pipe products offer structural strengths and corrosion resistance for optimum performance within high pressure applications. FRP is lightweight, extremely strong, easy to install, and resistant to deterioration.
Their resistance to water and sewage systems acidic environment is another advantage. Our GRP pipes are mainly used for transporting drinking water, sewage drainage and seawater, in addition to desalination water, chemical and industrial residues, fire-fighting systems, cooling systems and irrigation. GRP pipes can be manufactured in custom diameters and in any required length. This helps in easy installation
especially in rehabilitation lining projects.
Benefits
※Long Service Life
Pipes are designed in compliance with the international standards to serve a minimum of 50 years. Operating and maintenance costs are negligibly small. .
※Safe Connections
GRP pipe joints are designed with the flexible connection method, and the sealing is provided by couplings having full-face integrated elastomeric seal.
※Surge Pressure Absorption
Additional pressure increases occurring due to surges are far less when compared with metal pipes. They are designed to absorb 40% of the surge pressure, without increasing the pressure class.
