Hydropower
GRP is used as transmission and pumping mains in hydroelectric plants and other energy facilities.
Mechanical strength and durability
In a hydroelectric plant, the mechanical strength and durability of the pipes are essential. GRP offers a smooth wall, which greatly reduces hydraulic head losses, and weighs about a quarter of steel.
- No corrosion: no special coating, no cathodic protection
- Low hydraulic head losses
- Water hammer: surge pressures clearly lower than on metal pipes, with up to 40% of the surge absorbed without increasing the pressure class
- Lightweight: handling without heavy equipment, fast assembly

Filament-wound GRP ranges from DN 200 to DN 4000.
Frequently asked questions
What pressures can a GRP pipe withstand?
It depends on the diameter and the pipe design; it is sized for the working pressure of your structure. We will give you the values that apply to your case.
