Indus Industrial Group supplies continuous filament wound Glass-Reinforced Plastic (GRP) Potable Water Pressure Pipes manufactured in nominal diameters from DN300 (12") to DN3000 (120") across pressure ratings PN6, PN10, PN16, PN20, and PN25 with ring stiffness classes SN2500, SN5000, and SN10000 N/m². Engineered to European Standard EN 1796, ISO 10639, and AWWA C950, these composite pipes combine high-strength continuous fiberglass roving, thermosetting polyester/vinyl ester resins, and graded silica sand core to create corrosion-proof, lightweight mega-diameter water transmission trunk mains across Iraq.

Mega-diameter municipal drinking water transmission mains, raw river water intake trunklines, desalted water transfer pipelines, and power plant cooling water circuits in Baghdad, Basra, Muthanna, Dhi Qar, and Maysan.
High-capacity municipal water transmission across Iraq—linking water treatment plants along the Tigris and Euphrates rivers to provincial distribution reservoirs—requires mega-diameter piping capable of withstanding corrosive, gypsum-rich, and saline soils without costly cathodic protection. GRP Potable Water Pressure Pipes provide an engineered composite structure with a rich internal resin liner (minimum 1.0mm thickness) certified non-toxic and neutral to drinking water hygiene according to WRAS and NSF/ANSI 61.
The continuous filament winding manufacturing process aligns glass fibers in both circumferential and axial directions, providing high hoop tensile strength to withstand operating pressures up to 25 Bar and sudden pump shutoff water hammer surge pressures. The lightweight nature of GRP (one-fourth the weight of ductile iron and one-tenth the weight of reinforced concrete) drastically slashes transportation costs from port to site and allows rapid laying using standard excavators without mega-cranes.
Jointing is achieved via integrated double-bell mechanical couplings fitted with precision EPDM elastomeric sealing gaskets conforming to EN 681-1, permitting angular deflection up to 3 degrees per joint to navigate natural ground contours. Backed by hydro-testing certificates and EN 10204 3.1 inspection reports, Indus maintains extensive project pipeline stocks in Erbil and Basra.
GRP is completely non-metallic and immune to soil galvanic corrosion, stray electrical currents, and sulfide attacks. Unlike steel or ductile iron, GRP never requires cathodic protection or exterior zinc/polyurethane recoating.
GRP pipes are designed and tested according to ASTM D3517 and ISO 10639 for a minimum structural service life of 50 years under continuous hydrostatic pressure and soil load.
Yes. GRP pipes with isophthalic resin are rated for continuous media temperatures up to +50°C without pressure derating, making them ideal for surface-laid or shallow-buried desert pipelines.
