Indus Industrial Group supplies heavy-duty All-Flanged Ductile Iron Equal and Reducing Tees engineered across nominal diameters from DN80 to DN2000 in pressure ratings PN10, PN16, PN25, and PN40 according to EN 545 and ISO 2531 standards. Cast from high-grade spheroidal graphite iron (Grade 500-7) with minimum 420 MPa tensile strength, these flanged tees are protected with electrostatically applied blue fusion-bonded epoxy (FBE, min 250 µm) or centrifugally applied cement mortar lining. Engineered for high-head pumping stations, water treatment plant piping manifolds, and urban valve distribution chambers across Iraq, they feature precision-machined EN 1092-2 flanges capable of withstanding immense hydraulic branch thrust.

Water treatment plant filter gallery manifolds, booster pump station suction/discharge headers, municipal valve chambers, river raw water intake bypass assemblies, and major municipal distribution branch points across Baghdad, Erbil, Basra, Najaf, and Karbala.
All Flanged Ductile Iron Equal and Reducing Tees represent the core structural manifold components for high-pressure municipal water transmission, river raw water intake stations, and water treatment plants (WTPs) across Iraq. Formulated strictly according to EN 545, ISO 2531, and BS EN 545 standards, these tees are manufactured using centrifugally and statically cast spheroidal graphite iron with nodularity exceeding 85%. The heavy wall thickness profile absorbs extreme mechanical bending moments, vibrational harmonics from operational booster pumps, and severe hydraulic water hammer shocks common in Iraqi municipal grids during electrical power trips.
Corrosion protection is engineered to international standards: either 100% holiday-free blue fusion-bonded epoxy (FBE) coating applied per EN 14901 (certified non-toxic for drinking water per WRAS/BS 6920), or high-density blast furnace slag cement mortar lining. All three flange connections are integrally cast and precision-drilled strictly according to EN 1092-2 and ISO 7005-2 in PN10, PN16, and PN25 pressure classes, ensuring flawless mating with gate valves, non-return valves, and pump discharge nozzles.
Under real-world Iraqi field conditions, where valve vaults frequently accumulate high-salinity groundwater in southern cities like Basra and Amarah, the exterior epoxy barrier prevents electrochemical corrosion and subsoil graphitization. Backed by extensive warehouse inventory at the Erbil Heavy Plant Yard, Baghdad Central Logistics Hub, and Basra Port Corridor, Indus Industrial Group provides complete tee fittings with EN 10204 3.1 mill test certificates, dimension verification, and hydrotest compliance.
Indus stocks the complete matrix of standard equal and reducing tees (e.g., DN300×150, DN400×200, DN600×300, DN800×400) at our Erbil, Baghdad, and Basra facilities. Custom reducing branches are mobilized on rapid schedules.
The fusion-bonded epoxy is electrostatically applied to preheated castings (200°C) to form a seamless cross-linked polymer film of at least 250 microns. It is tested for zero pinholes (holiday test at 1.5 kV) and prevents galvanic corrosion even if the chamber is flooded with saline groundwater.
Each batch is delivered with an authentic EN 10204 3.1 Mill Test Certificate verifying metallographic nodularity (>85%), tensile strength, hydrostatic factory testing, and coating thickness measurements for ministerial approval.
