GRP Pipes for Water, Sewerage, Irrigation and Industrial Applications

Description

High-quality Glass Reinforced Plastic (GRP) pipes manufactured by Al Najma Al Watanya using Continuous Filament Winding technology. These lightweight, corrosion-resistant pipes provide excellent hydraulic performance and long service life. They are suitable for water transmission, sewerage, wastewater, irrigation, industrial process lines, cooling-water systems, oil and gas facilities, power plants, desalination and marine applications. SPECIFICATIONS • Product: Glass Reinforced Plastic (GRP) Pipe • Manufacturing method: Continuous Filament Winding (CFW) • Pressure classes: PN1–PN32 bar • Stiffness classes: SN1250–SN10000 N/m² • Standard lengths: 6 meters and 12 meters • Custom lengths: Available upon request • Main materials: Fiberglass reinforcement, polyester resin and silica sand • Jointing system: GRP coupling with EPDM sealing rings • Properties: Corrosion, abrasion and chemical resistance, with UV protection available upon request. • Installation: Lightweight and easy to transport and install • Customization: Diameter, pressure class, stiffness class, length and joint configuration can be produced according to project requirements Available Sizes: DN300, DN350, DN400, DN450, DN500, DN600, DN700, DN800, DN900, DN1000, DN1100, DN1200, DN1300, DN1400, DN1500, DN1600, DN1700, DN1800, DN1900, DN2000, DN2100, DN2200, DN2300, DN2400, DN2500, DN2600, DN2700, DN2800, DN2900 and DN3000. Quality Testing: Each GRP pipe undergoes visual inspection (ASTM D2563), dimensional checks (ASTM D3567) and Barcol hardness testing (ASTM D2583). Batch samples are tested for hydrostatic pressure (ASTM D2992), pipe stiffness and deflection (ISO 7685 and ASTM D2412), axial tensile strength (ASTM D638 and ISO 3268), hoop tensile strength (ASTM D2290 and ISO 8521), and Loss on Ignition (ASTM D2584). APPLICATIONS Potable and raw-water transmission, sewerage and wastewater networks, stormwater drainage, agricultural irrigation, industrial and chemical pipelines, cooling-water systems, oil and gas facilities, power generation, desalination, marine and hydropower projects.
