DI-RACK
Extra-high strength for special offshore applications
DI-RACK plates, with minimum yield strengths starting at 690 MPa combined with excellent toughness properties, are the solution for heavily stressed structures in the offshore oil and gas industry. DI-RACK is used, for instance, in the legs of wind-turbine installation vessels and in mobile production platforms, so-called jack-up rigs, for the racks of the jacking system.
The strengths of DI-RACK proprietary steel
- DI-RACK is a quenched and tempered fine-grained structural steel with constant yield strengths throughout the entire thickness range up to 210 mm: 690 MPa for Type B and 723 MPa in Types M and S, which additionally feature enhanced tensile strengths.
- DI-RACK offers optionally improved deformation properties perpendicular to the plate surface for plates exposed to loads in the thickness direction.
- DI-RACK possesses not only ultra-high mechanical strength but also excellent toughness properties throughout the plate cross-section at test temperatures of down to -60° C, depending on the customer’s specification.
- Dillinger possesses ABS and DNV approvals for plates in the 690 MPa yield-strength class.
