The excellence of ductile cast iron at the service of renewable energy

HYDROPAM is a set of solutions for hydroelectric power stations that includes ductile iron pipes, fittings, joints, valves and accessories. The range has equipped 500 hydroelectric power plants in Europe.
Even with high speeds and large volumes of water, the high hydraulic performance of HYDROPAM mean that the velocity of the water can be maintained without alteration.
Robust, reliable and durable ductile iron fits perfectly into the time and space continuum of hydroelectric power stations that are installed for several decades.
For more than 40 years and in over 15 countries, PAM sustainable productc has contributed to the increase in production of renewable electricity.


  • Protection: internal lining composed of a layer of cement mortar with a smooth, regular finish that prevents head losses and subsequent hydraulic energy and financial losses in the context of hydroelectricity. The smooth internal surface also means that there is exceptional resistance to abrasion from raw water flowing at very high speeds.
  • Resistance: external protective coating made of a metallic layer of zinc covered with a layer of pore sealer guaranteeing a high resistance to impacts during transport, processing, storage and backfilling.
  • Economical: savings on fittings, reduction of head losses, and the most direct routes possible in mountainous regions, due to HYDROPAM's considerable angular deflection despite its large diameters.
  • Outstanding safety and reliability: the anchoring solutions of HYDROPAM pipes, which include anchored joints, make it possible to lay several hundred metres of pipes on a steep slope with only one anchorage point at the summit.
  • Ease of assembly: standard work site equipment can be used in a trench with no necessary welding, as a result of the socketed joint technology.
  • Reliability of the pipes: ensured by drawing up a rigorous quality plan during the manufacturing process and conducting resistance tests on the products.
  • All-terrain logistics: our teams will put in place carefully orchestrated logistics that integrate both site constraints and project calendar and weather requirements. We will deliver products to places that are very difficult to access, in the shortest possible time, in order to respect your deadlines.
