Indus Industrial Group manufactures and stocks precision Double Flanged Ductile Iron Pipes across nominal diameters from DN80 to DN2000, compliant with EN 545, ISO 2531, and EN 1092-2 flange drilling standards. Engineered for rigid, high-integrity mechanical connections in municipal water treatment plants (WTP), wastewater treatment works (WWTP), high-head booster pump galleries, valve chambers, and suspended bridge crossings throughout Iraq, these pipes are available with integrally cast flanges or precision screwed/welded flanges rated for PN10, PN16, PN25, and PN40 pressures. Each pipe spool is protected with internal potable-certified blast furnace cement mortar or high-alumina cement lining, paired with heavy external zinc thermal spray and epoxy or polyurethane finishing paint. Manufactured in standard lengths from 0.5m to 6.0m with custom fabrications available, these flanged spools guarantee zero angular deflection, precise face-to-face dimensions, and leak-tight jointing under continuous vibration.

Water treatment plant (WTP) filter and pump galleries, wastewater treatment plant (WWTP) blower and sludge lines, deep valve and meter chambers, river intake pump manifolds, elevated pipe bridge crossings, and industrial power plant cooling water circuits across Baghdad, Erbil, Basra, Najaf, and Sulaymaniyah.
Double Flanged Ductile Iron Pipes provide the rigid structural backbone for water treatment plants, booster pumping stations, and valve inspection chambers across Iraq where pipelines must connect securely to heavy pumps, butterfly valves, check valves, and air release manifolds without joint slippage. Unlike flexible push-on joints that accommodate ground settlement, flanged connections provide completely rigid, tensile-restrained joints capable of transferring longitudinal mechanical stresses and dynamic vibration generated by high-power electric pumping units. Indus Industrial Group supplies EN 545 and ISO 2531 compliant double flanged ductile iron pipe spools with flange dimensions and bolt hole drilling adhering strictly to EN 1092-2 and ISO 7005-2 for PN10, PN16, PN25, and PN40 pressure ratings.
Our manufacturing processes incorporate three distinct flanged pipe architectures: integrally cast flanges (where flange and barrel are cast as a single monolithic component), screwed flanged pipes (where high-precision threads are machined into the barrel and heavy-duty threaded flanges are screwed on with thermosetting epoxy sealants), and welded flanged pipes. All flange sealing faces feature precision-machined raised faces or flat faces with concentric or spiral serrations (per ASME/EN standards) that optimize gasket seat stress and ensure drop-tight sealing with EPDM, NBR, or reinforced spiral-wound metallic gaskets.
Every flanged spool undergoes strict dimensional inspection to ensure parallel flange faces, squareness to the pipe axis, and exact face-to-face tolerance (±2mm), eliminating installation strain on connected valves and rotating equipment. Internally lined with centrifugally compacted blast furnace cement or 100% solid polyurethane, and externally coated with galvanic zinc plus heavy two-pack epoxy (minimum 250 µm for exposed piping), these pipes resist both process liquid corrosion and atmospheric weathering under the intense Iraqi sun. Staged in our Erbil, Baghdad, and Basra logistics hubs, Indus provides rapid delivery of standard lengths (1m, 2m, 3m, 4m, 5m, 6m) as well as custom make-to-measure spool pieces.
Ductile iron flanged pipes offer vastly superior corrosion resistance, better acoustic and vibration damping from running pumps, and consistent wall thickness without internal weld bead roughness. Their factory-applied cement or epoxy lining will not delaminate, providing a lifespan exceeding 50 years without cathodic maintenance.
Yes. While standard lengths (0.5m to 6.0m) are stocked in Baghdad, Erbil, and Basra, Indus Industrial Group provides custom precision-machined flanged spools manufactured to exact contractor millimeter drawings to fit seamlessly into retrofit chambers and tight valve vaults.
All flanges are drilled strictly to EN 1092-2 / ISO 7005-2, which is the universal standard for PN10, PN16, PN25, and PN40 valves and pumps installed across Iraqi municipal and industrial facilities.
