Douce-Hydro is committed to providing you with products of impeccable quality, thanks to a rigorous and comprehensive qualified control system. Our aim: to guarantee you reliable, long-lasting hydraulic solutions that meet the most exacting requirements.

Our strengths in quality control:

  • Dimensional and geometric control :
    • Check all component dimensions using precise measuring tools;
    • Check component geometry to ensure optimum operation.
  • Checking welds :
    • Visual inspection of welds by certified technicians;
    • Dye penetrant inspection or radiography to guarantee weld quality.
  • Control of surface treatments :
    • Checking the thickness and adhesion of surface treatments;
    • Controlling the corrosion resistance of surface treatments ;
    • Assessment of salt spray corrosion performance (600l capacity).

Hydraulic and functional tests :

  • Low-pressure static and dynamic pressure testing to guarantee component resistance;
    • Fatigue test to simulate real-life conditions;
    • Function test to check that products are working properly.
  • Strict safety procedures:
    • Compliance with current standards and regulations;
    • Use of test equipment.

Thanks to these procedures and this traceability system, we can guarantee :

  • Safe, reliable products that meet the highest standards;
  • Complete traceability of your products, from raw material to finished product;
  • Peace of mind knowing your products are in good hands.
