The ductile iron pipe for large aqueducts of water mains

Ideal for conveying large volumes of water, the ductile iron pipes and fittings of the CLASSIC range are available in diameters of between 700 and 2,000 mm.

As a complement to the NATURAL range, the large-diameter CLASSIC range has been equipping large aqueducts of water mains on various continents for a long time. It has earned a solid reputation as the range of choice among contracting companies and stakeholders around the world for large projects.

Multipurpose: robust and easy to install using standard work site tools, CLASSIC ductile iron pipes are suitable for long-distance transport by truck, train or boat, and for use in all types of geographical terrain, including difficult locations such as mountains, deserts, forests and swamps.

Durability: ductile iron, obtained by a special Magnesium treatment, has an elastic behaviour that confers outstanding mechanical properties on the metal. It is tough and resistant to impact; has a considerable elongation (bending) capacity (>10%) and elastic limit (>270 MPa); and is rigid with minimal deformation.

Reliability: the elastomer gaskets allow a modular pipeline system as well as ensuring operational reliability by guaranteeing leak tightness of the socket and spigot joint. The flexibility of the gaskets facilitate the curvature of the pipeline, turning around of obstacles, and the crossing of the majority of zones, even with constraints such as steep slopes, rocky areas, laying below the water table and river crossings.

Stability: our robust pipes can withstand high external loading and environmental changes such as ground movements, pipe undermining, and bedding destabilization without fracturing, cracking or disjointing. Moreover, they are designed with a high safety factor, exceeding that required in service, in order to accommodate not only high continuous service regimes, but also any over pressures and water hammer without installation deterioration.

Supply, Treatment and Distribution

Ductile iron pipe solutions for the complete water cycle  

We supply our PAM ductile iron pipelines throughout the world, allowing water to be transported from its source to treatment plants and places of consumption. Our solutions address water whether it is potable, raw, waste or recycled, and cover the entire water transport cycle, from its gravity supply, surface and ground water filtration and seawater desalination, treatment and storage, and distribution to consumers and industry.

As investment in renewing water supply infrastructure is declining in relative terms, there is increasing demand on pipeline service longevity. Our ductile iron pipes, fittings, valves and accessories are anti-ageing and have earned a first-class reputation for both leak tightness and pressure resistance.  

We are involved in both the preservation of the quality and quantity of water as a resource and its distribution in all situations, where there may be  mechanical stresses, pressure surges, or environmental constraints among other challenges.

For the supply of water alone, we have 10,000 items of pipes, fittings and joint compounds to cope with every possible situation and to withstand all hazards associated with their transport, handling, installation and operation.
