In the marine sector, as in the infrastructure sector, the ability to operate in salty and highly corrosive environments is crucial, which is why materials such as stainless steel and double nickel and chrome coatings are often required for certain applications. Here are some application examples of cylinders that have been manufactured specifically for this area of use. HIDROMEC develops hydraulic cylinders and systems for maritime applications that are reliable, durable and comply with the relevant environmental standards.

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.

The steel industry is a specific sub-sector of the stationary industry. The term steelmaking refers to a specific area of metallurgy that involves the technique of processing iron-rich ore to produce iron or various types of ferrous alloys, including steel, pig iron and alloy steels. The steel industry needs very reliable and robust equipment: no malfunction is allowed. Rolling mills and furnaces must not be stopped by a defective hydraulic cylinder. The main features of the cylinders used in this sector, apart from ensuring high reliability, are that they are designed to operate in dusty environments and at very high ambient temperatures, even above 100°C. This makes it necessary to equip the cylinders with seals that retain their functionality even at such high temperatures. Seals and gaskets made of special fluorocarbonate material (Viton) are used. HIDROMEC develops hydraulic cylinders and systems for applications in the steel industry that are reliable, durable and comply with the relevant environmental standards.

Hydraulic cylinder applications in the stationary industrial sector are diverse: hydraulic presses of all kinds, ranging from presses for sheet metal forming and presses for the plastics industry to filter presses and scrap presses. Roll forming machines are also included, as well as machines and industrial equipment of various kinds. Equipment in constantly changing shapes and sizes gives us the opportunity to apply the design know-how we have acquired over forty years of dedication to meeting a wide variety of customer requirements. Hidromec develops hydraulic cylinders and systems for equipment with applications in the industrial sector that are powerful, durable and comply with the relevant environmental standards.
