Indus Industrial Group supplies premier Class C ductile iron pressure pipes ranging from DN80 to DN2600, engineered strictly in accordance with EN 545 and ISO 2531 international standards for potable water transmission and urban distribution networks across Federal Iraq and the Kurdistan Region. Manufactured from high-grade spheroidal graphite cast iron with a minimum tensile strength of 420 MPa and elongation exceeding 10%, each pipe segment features an internal centrifugally applied blast furnace slag cement mortar lining (compliant with BS 6920 and WRAS drinking water hygiene certifications) and an external zinc metallic coating (200 g/m²) sealed with an anti-corrosive synthetic blue topcoat. Equipped with flexible push-on Tyton sockets and synthetic EPDM elastomeric gaskets, these pipelines provide angular deflection up to 5 degrees without leakage, accommodating ground shifting and thermal expansion under Iraq extreme summer ground temperatures.

Municipal potable drinking water transmission networks, raw water intake transmission lines from Tigris and Euphrates, booster pump delivery pipelines, deep burial urban water distribution grids, and provincial water treatment plant (WTP) distribution arteries across Baghdad, Erbil, Basra, Mosul, and Karbala.
Class C Potable Water Ductile Iron Pipes represent the foundational engineering benchmark for major urban water conveyance across Iraq, meeting the stringent procurement standards of the Baghdad Water Authority, Ministry of Construction, Housing & Municipalities, and regional Water Directorates. Fabricated through centrifugal casting of ductile iron with spheroidal graphite nodules (Grade 500-7 / 420-10 per ISO 1083), these pipelines offer exceptional beam strength, burst resistance, and crush resilience compared to brittle conventional materials. Every pipe is lined internally with centrifugally compacted blast furnace cement mortar, creating an ultra-smooth hydraulic interior (Hazen-Williams coefficient C=140–150) that prevents tuberculation, eliminates internal biofilm accumulation, and sustains maximum volumetric throughput with minimal pumping head losses over a 100-year design lifecycle.
From a structural and mechanical perspective, the Class C designation classifies each pipe by its maximum allowable operating pressure (C25 for 25 Bar, C30 for 30 Bar, C40 for 40 Bar, C50 for 50 Bar, C64 for 64 Bar, and C100 for 100 Bar), delivering unmatched safety margins against hydraulic water hammer and transient pressure surges. The flexible Tyton push-on joint system eliminates the need for field welding or specialized hot-work permits, utilizing precision-molded EPDM dual-hardness sealing gaskets that absorb longitudinal expansion, contraction, and seismic ground vibrations. External corrosion protection is achieved through a multi-tier barrier consisting of metallic zinc or zinc-aluminum alloy thermal spray (200 g/m² to 400 g/m²) followed by a cross-linked synthetic resin or bitumen finishing pore sealer (minimum 70 microns), preventing atmospheric and subsoil electrochemical attack.
In real-world deployment across Iraq, these ductile iron pipelines withstand harsh ambient extremes ranging from sub-zero winter nights in the northern mountains of Erbil and Sulaymaniyah to blistering desert soil temperatures exceeding +55°C in Basra, Muthanna, and Dhi Qar. Indus Industrial Group maintains extensive in-country staging yards at the Erbil Heavy Plant Yard, Baghdad Central Logistics Depot, and Basra Port Corridor, guaranteeing rapid delivery of complete pipeline runs with mill test certificates (EN 10204 3.1) and technical engineering support direct to job sites across all 19 Iraqi governorates.
All ductile iron pipes supplied by Indus Industrial Group strictly comply with EN 545 (potable water) and ISO 2531 standards. Each delivery is accompanied by an authentic EN 10204 3.1 Mill Test Certificate verifying hydrostatic pressure testing (100% factory tested), spheroidal graphite nodularity (>85%), chemical metallurgy, and cement lining thickness.
The blast furnace slag cement mortar lining is centrifugally applied under high velocity, creating a dense, smooth matrix. This lining passivates the iron surface and prevents internal tuberculation, maintaining a constant Hazen-Williams hydraulic coefficient of C=140–150 even when carrying raw river water from the Euphrates or Tigris with high mineral hardness.
Indus maintains substantial pipeline inventory at our Erbil Heavy Plant Yard, Baghdad Central Depot, and Basra Port Corridor. Standard diameters (DN100 to DN800) can be mobilized to job sites across all 19 governorates within 24 to 72 hours, while project-scale orders (DN900 to DN2600) are scheduled with dedicated logistics convoys.
