Designing & Managing Hydraulic Systems Solutions
Douce-Hydro, founded in 1950, is a leader in hydraulic cylinder and system design and manufacturing. Since 1990, it has been a family-owned business under Jean-Marc Vandenbulke, expanding internationally with subsidiaries in the USA and Germany. The acquisition of Jarret Structures in 2008 broadened its product offerings in seismic and civil engineering.
Douce-Hydro has the largest manufacturing capabilities in its industry, with 24,000 sqm of facilities equipped with advanced machinery for various processes. The company has invested in CNC machinery to handle large-scale projects efficiently.
The engineering team, consisting of 20 professionals, uses CAD-CAM Siemens NX software to ensure high-quality and cost-effective designs. Innovation and research are prioritized to develop advanced solutions.
Emphasizing pre-project reviews and client communication, Douce-Hydro's project management team ensures effective specification management and project follow-up, collaborating closely with clients throughout the project lifecycle.
With ISO 9001:2008 certification, Douce-Hydro prioritizes quality through rigorous testing procedures and certified welders, ensuring full product traceability.
The company features a new assembly hall and advanced equipment for sandblasting, painting, and testing, including a high-capacity hydraulic test bench and a clean room for metrology.
Douce-Hydro is a key player in hydraulic systems, known for its commitment to quality and innovation, with a strong global presence and extensive manufacturing capabilities.
The document details hydraulic systems and components, focusing on piston accumulators, hydraulic power units, and advanced coatings for hydraulic cylinders, highlighting their applications in various industries, especially offshore.
Technical specifications for piston accumulators include dimensions, operating pressures, and capacities. Coatings like KERADOUCE®, MetalteKTM, and LaserteKTM are noted for their corrosion and wear resistance.
Testing procedures for coatings, such as salt spray tests, adhere to ASTM and DNV standards. The SMIKTM sensor system is ATEX certified.
Douce-Hydro recommends its custom hydraulic systems for high-reliability applications, advising on appropriate coatings based on environmental conditions to extend cylinder lifespan.
- SMIKTM Sensor: Provides data on rod position, velocity, and acceleration, certified for explosive atmospheres.
- KERADOUCE® Coating: Offers high corrosion resistance, replacing traditional nickel-chrome coatings.
- MetalteKTM Coating: Provides medium corrosion resistance with high hardness.
- LaserteKTM Coating: A weld overlay process for extreme environments, meeting DNV standards.
Hydraulic systems are used in tensioners, compensators, and cylinders for offshore and industrial settings, adaptable to different materials and coatings based on application needs.
Douce-Hydro's hydraulic cylinders are used in marine, civil engineering, renewable energy, military, and industrial applications, with specific examples in each sector.
Discusses seismic protection systems for buildings and bridges, including damping devices and base isolation, with a focus on the "Spider" type preloaded spring damper.
California office buildings 8&9 in Sacramento utilize 256 viscous fluid dampers with specific load and velocity ratings.
Douce-Hydro has a global presence with headquarters in France, the USA, and Germany, providing worldwide technical assistance.
