  • Polyolefin coated steel pipes
    Patent number: 8415447
    Abstract: Polyolefin coated steel pipes with high dynamic fracture toughness of the coating of the steel pipes during installation handling and in service, consisting of a steel pipe core, optionally an intermediate foamed plastic material, and a polyolefin coating of ?-nucleated propylene copolymers whereby a test polyolefin pipe fabricated from the ?-nucleated propylene copolymer has a critical pressure of >25 bars and a dynamic fracture toughness >3.5 MNm?3/2. The polyolefin coated steel pipes are suitable for off-shore transport of crude oil or gas products or district heating applications.
    Type: Grant

  • Singlelayer and multilayer polyolefin foam pipes
    Patent number: 7462307
    Abstract: Process for producing single layer and multilayer polyolefin foam pipes with improved compression resistance having a polyolefin foam layer which consists of mixtures of modified propylene polymers having strain hardening behaviour or propylene homopolymers with a stereospecificity index >98% or propylene copolymers with a stereospecificity index of the homopolymer matrix of >96%. The polyolefin foam pipes include coated steel pipes for transporting crude oil or gas products or district heating applications, single layer pipes for insulation purposes and for non- or low-pressure applications and multilayer plastic pipes for the transportation of hot or cold fluids.
