Hydroclass Range

The perfect ductile iron pipe for robust and flexible water distribution networks in all situations

Through knowledge gained by our dedicated research centre in areas such as soil corrosion phenomena, our ductile iron pipelines have the latest coating technologies and often exceed minimum industry standards. Our joints are also developed and tested here in the most extreme conditions.

HYDROCLASS pipes are available with Zinalium or with a pure zinc coating. As soon as it comes in contact with soil, a zinc-based coating generates an overall protective layer that constitutes a real shell for buried ductile cast iron pipelines. Compared to a pure zinc coating, Zinalium triples the service life of the protective layer.  

The ductile iron pipes and fittings in the HYDROCLASS range are available with diameters between 100 and 2,000 mm.

Benefits

All PAM products comply with the current European (EN) and international (ISO) standards.
Through the work of PAM research centre and their knowledge of corrosion phenomena in the soil, the PAM ductile iron pipelines have the latest coating technologies and often exceed the minimum industry standards.
It is also in this centre that the joints are developed and tested in the most extreme conditions.

Robustness and resistance: ductile cast iron is a robust material, which withstands high service pressures and external mechanical accidents, and is impervious to pollution in soil. Benefitting from its mechanical properties, the HYDROCLASS joints with flexible sockets ensure water tightness, while the coatings protect the pipeline from external corrosion and preserve the water quality in a sustainable manner. Our parts can withstand transportation conditions by truck, train, and ship, as well as stacks of stocks and rough handling on work sites.

Flexibility: from desert to swamp, our products, their protection and assembly are designed for all terrains, climates and situations. Irrespective of the temperature and humidity levels, there is no waiting time when using the excavator for straight lines at high rates and simple hand winches at the bottom of inaccessible trenches. The short pipe facilitates access with equipment of standard size and favorably limits the site’s right-of-way strip

Simplicity of installation: the ease of pipe laying, aligning and fitting of our ductile cast iron pipes with sockets result in high production rates on work sites. There is no need for any welding, coating repair, or ultrasonic exam, nor the immobilisation of specialised equipment or waiting time for the drying or cooling of assemblies. The technologies developed at Saint-Gobain PAM give unrivalled management flexibility of work sites (shutdowns, restarting and progress).

Longevity: international statistics show that cast iron pipelines have service lives exceeding 100 years, while networks must continually adapt to urban, industrial, agricultural, and tourist developments. Saint-Gobain PAM pipelines are designed with a safety reserve that securely withstands increases in flow, pressure, and surface loads of roads and buildings. Our complete solution of pipes, fittings, joints and accessories ensure the perfect compatibility of installations.
