Gruppo Donelli: services for the hydroelectric industry
In the hydroelectric sector, Donelli specializes in anti-corrosion coatings and technical maintenance of metal and reinforced concrete structures, with decades of experience earned on plants of all types and sizes.

We carry out complete interventions on:

Penstocks (internal and external), valves, turbines, distributors, floodgates, grids, tanks;
Civil structures in reinforced concrete subject to degradation or carbonation;
Surfaces subject to immersion, condensation, erosion or cavitation.
Corrosion protection activities include:

Ultra-high pressure hydroblasting up to 3,000 bar, also robotized, with water recovery and filtering solutions;
Internal/external sandblasting with automatic trolleys, turbines or remote-controlled nozzles;
Application of high-performance multilayer coatings (epoxy, ceramic, zinc, polyurethane), including solvent-free;
Shot blasting of pitted areas to reduce turbulence and cavitation;
Structural reinforcement with composites as per ISO 24817 and ASME PCC-2, also with FEM analyses.
Each process is controlled by Wi-Fi systems with remote control panels and internal video monitoring. The thermo-hygrometric conditions are kept constant throughout the application to ensure proper polymerization of the coating.

We can operate at height, in tunnels or in isolated environments, with sectional and helicopter-transportable equipment, in compliance with environmental and safety regulations and with containment and confinement systems. We guarantee the maintenance of the efficiency of hydroelectric infrastructure and the prevention of loss of useful section due to localized corrosion.
