Penstock for hydropower plant

Ductile Iron Piping Solutions for Mini Hydropower Plants

Penstocks are usually located in complex terrain, rougged terrain and / or geotechnical instability, and withstand high operating pressures. For this reason, they demand materials and equipment suitable for extreme needs.

The connection system must be easy and simple, providing high installation performance, and not only provides a high safety coefficient but in its more than 50 years of useful life, the pipes are kept safe, watertight and fully operational once start the operation All These without maintenance!

Case of Success

SAMUC Hydropower plant

High and low pressure driving.

Alta Verapaz, Guatemala.


Located in the Alta Verapaz area of ​​Guatemala, the SAMUC hydropower plant project has two pipelines that go to the same machine room: the SAMUC I line at ND 400 and the SAMUC II line at ND 600. Both were built with a crane cable transport system due to the complex installation conditions of the pipes:

  • Slopes of the order of 480% (78º)
  • Different pressure sections up to a PMA of 52bar
  • Executed with pipe with locking system

Keys to project success

  • Hacer de un proyecto imposible algo viable, seguro y rentable
  • La supervisión y control hasta la prueba de presión por el propio equipo de diseño
