Offshore Hydraulik: A High Performance Material out of Continuous Cast Iron



A High Performance Material out of Continuous Cast Iron from Gontermann-Peipers now also available for Offshore Applications

Extended Field of Operation for Cast Iron from Gontermann-Peipers

Designers and users of hydraulic blocks have confi dence in the proven ductile cast iron material GOPAG C 500 F® since many years. Its fi ne and purely ferritic structure enables precise machining at high speed. Together with the lower
mass density compared to steel cost and weight reductions are already possible.

However the application and use of ductile cast iron materials in offshore applications, like wind energy, maritime, oil and gas, is limited due to strong requirements on the safety factors during design.

As specialist for high performance cast iron Gontermann-Peipers succeeded in getting continuous cast iron qualified for offshore applications. The material GOPAG C 500 F®, the product name for EN-GJS-500-14C from Gontermann-Peipers, has been qualified by the well-known classification society DNV-GL and can be ordered with this additional property on request.

Benefits

  • Safety during mechanical design also at high operational pressures
  • Substitution of steel*
  • Weight reduction up to 23%* realized by lower part dimensions
    and lower mass density
  • Cost reduction during machining at higher speed and based on the high process stability
  • Precision and accuracy during machining also for deep drilling
    and at sealing surfaces based on the homogeneity of the material

* Dependent on the specific load situation, the component size and the applied method for the safety dimensioning
