Civil engineering is the branch of engineering responsible for the design of artefacts and infrastructures for civil use and thus for all related fields: civil engineering, hydraulic engineering, geotechnics, infrastructure, structural engineering, urban planning.
Hydraulic engineering is characterised by hydraulic applications that operate in very demanding areas with a high risk of wear: River dams, locks and weirs require cylinders that are operational under water. The use of piston rods made of stainless steel material and/or rods with NiCr or ceramic coatings are often required for these applications
Hidromec develops hydraulic cylinders and systems for hydraulic engineering applications that are reliable, durable and comply with the relevant environmental standards.

Hydraulic Engineering
The most common applications in hydraulic engineering or building construction for which we develop cylinders are:
A dam is a permanent man-made barrier, fixed or movable, used to regulate the flow of a natural watercourse, create a reservoir or protect a stretch of coastline or harbour.
Mobile dams and traverses in general are usually steel structures moved oil-hydraulically by cylinders. The cylinders used for dams are mainly used to lift the locks. They are very long (6 -10 m) and often require the use of piston rods made of special materials (stainless steel material) with special coatings (NiCr, Ceramax). These cylinders are extremely critical components as no malfunction is allowed. Often, for welded cylinders, the ultrasonic inspection of the weld seams as well as a corresponding certification is required.
Hydraulic cylinders are also used in hydropower plants to interrupt or reduce the high flow velocity of the water feeding the turbines to prevent turbine breakage. Radial sluices (also known as tainter sluices) are often used in dams and other power generation facilities.
Hydraulic dampers use fluids to convert the mechanical energy of an earthquake into thermal energy. Seismic dampers can be designed for linear damping, rotational damping or in other civil engineering applications for different movements, as in various other industrial and non-industrial applications. Finally, large hydraulic dampers are used in building construction (buildings or critical industrial facilities) to reduce the structural vulnerability of buildings from damage caused by the resonance of seismic waves.
