Indus Industrial Group supplies heavy-duty Double Flanged 90-Degree and 45-Degree Ductile Iron Bends engineered across nominal diameters from DN80 to DN2000 in pressure classes PN10, PN16, PN25, and PN40 according to EN 545 and ISO 2531 standards. Cast from high-strength spheroidal graphite ductile iron (EN-GJS-500-7) with minimum 420 MPa tensile strength, these flanged bends feature integrally cast EN 1092-2 flanges and blue fusion-bonded epoxy (min 250 µm, WRAS drinking water certified) or high-alumina cement mortar lining. Designed for high-pressure pump stations, water treatment plant galleries, and valve vaults across Iraq, they absorb severe hydraulic directional thrust forces.

Water treatment plant filter gallery manifolds, booster pump station suction/discharge headers, municipal valve chambers, river raw water intake bypass assemblies, and elevated pipe bridge crossings across Baghdad, Erbil, Basra, Najaf, and Karbala.
Double Flanged 90° and 45° Ductile Iron Bends represent the primary directional components for high-pressure pump station piping galleries, water treatment plant filter manifolds, and municipal valve chambers across Iraq. Governed by EN 545, ISO 2531, and BS EN 545 standards, these flanged elbows are cast from spheroidal graphite ductile iron with nodularity exceeding 85%. In rigid flanged piping systems, directional bends are subjected to immense dynamic hydraulic thrust forces generated by changes in fluid momentum, as well as vibrational harmonics from high-capacity booster pumps. The heavy wall thickness and high modulus of elasticity (170 GPa) of Indus ductile iron bends absorb these stresses without wall deflection or flange cracking.
Corrosion protection is provided by electrostatically applied blue fusion-bonded epoxy (FBE) coating (minimum 250 microns, tested for zero holidays at 1.5 kV) inside and outside, or internal centrifugal blast furnace slag cement mortar lining. Both flanges are integrally cast and precision-drilled strictly according to EN 1092-2 and ISO 7005-2 in PN10, PN16, PN25, and PN40 pressure ratings, ensuring leak-tight mating with flanged gate valves, butterfly valves, check valves, and pump discharge nozzles.
Under real-world Iraqi field conditions, where valve vaults frequently accumulate high-salinity groundwater in southern governorates like Basra and Dhi Qar, the holiday-free epoxy coating prevents galvanic corrosion and subsoil graphitization. Staged across our Erbil Heavy Plant Yard, Baghdad Central Logistics Depot, and Basra Port Hub, Indus supplies complete flanged bend packages with full EN 10204 3.1 inspection certification.
In flanged systems, the hydraulic thrust force generated at the bend is transmitted directly through the bolted flange connection and high-tensile bolts along the rigid pipe string to the nearest structural anchor, eliminating the need for massive soil thrust blocks inside plant chambers.
Yes. Indus supplies complete flanged installation kits containing hot-dip galvanized Grade 8.8 bolts, nuts, washers, and steel-reinforced EPDM full-face gaskets matching the exact flange drilling pattern.
Indus stocks standard flanged bends up to DN600 in high volume, and large sizes up to DN1200 at our Erbil, Baghdad, and Basra facilities for immediate dispatch across Federal Iraq and Kurdistan.
