Indus Industrial Group supplies custom-engineered GRP Fabricated Fittings and Flanged Spools manufactured in nominal diameters from DN300 (12") to DN2000 (80") in pressure classes PN10, PN16, PN20, and PN25. Our full range includes mitered elbows (11.25°, 22.5°, 30°, 45°, 60°, 90°), equal tees, reducing tees, concentric and eccentric reducers, puddle flanges, and flanged pipe spools compliant with ISO 10636, EN 1796, and AWWA C950 standards. Manufactured using precision segment cutting and vacuum-assisted resin lamination overwrap, these fittings guarantee structural continuity with GRP pipeline systems.

Water transmission valve chambers, sewage pumping station manifolds, desalination intake headers, and pipeline river crossing tie-ins in Baghdad, Basra, Erbil, Sulaymaniyah, and Dhi Qar.
Pipeline directional changes, branch takeoffs, and pump station valve chamber tie-ins in large-diameter GRP water and sewer networks require robust, precisely fabricated fittings capable of withstanding unbalanced hydraulic thrust forces and cyclic pressure surges. Indus GRP Fabricated Fittings are engineered to match the exact pressure rating, stiffness class, and resin chemistry of the adjacent pipeline, completely eliminating thermal expansion mismatch and galvanic corrosion.
Each fitting is crafted from factory-certified GRP parent pipe segments, cut on CNC bandsaws, and joined via multi-layered structural fiberglass overwraps utilizing high-tensile woven roving and chopped strand mat impregnated with vinyl ester or isophthalic resin. The structural lamination thickness is strictly calculated in accordance with BS 4994 and ASME Section X codes to ensure the joint overwrap exceeds the burst strength of the pipe barrel.
Flanged spools are supplied with integral GRP flanges or loose steel backing rings drilled to EN 1092-1 PN10/PN16 or ANSI Class 150 bolt patterns, allowing direct bolting to butterfly valves, gate valves, and flow meters in municipal valve vaults. Staged at our Erbil and Basra fabrication facilities with full hydrostatic proof-test reports.
GRP flanged spools are manufactured with flat-face or raised-face GRP flanges drilled to EN 1092-1 PN16 standards. They bolt directly to ductile iron gate or butterfly valves using full-face EPDM gaskets and galvanized steel backing rings.
Yes. Unless restrained lamination joints are engineered throughout the line, all pressurized GRP bends, tees, and reducers require concrete thrust blocks to anchor unbalanced hydrostatic thrust forces into surrounding soil.
Yes. Our specialized GRP fabrication shops in Erbil and Basra fabricate non-standard angles (such as 37.5° or 52°) and unequal tees according to contractor shop drawings with quick turnaround.
