  • Polyamide-sheathed structural steel tubes for offshore structures
    Patent number: 9982410
    Abstract: The foundation structure of an offshore structure, for example of an offshore wind energy system, is composed of steel tubes sheathed by an extruded layer made of a polyamide moulding composition. This simultaneously ensures both good protection from corrosion and good protection from mechanical effects, giving the foundation structure markedly prolonged lifetime.
    Type: Grant

  • Multilayer pipe with polyamide layer
    Patent number: 9551441
    Abstract: A pipe or pipeline for use in the oil and gas industry for conveying lines, collection pipelines and transport pipelines with reduced operating risk and increased lifetime is provided. The pipe contains: a) an external reinforcement layer and b) an internal liner which comprises securely bonded to one another: I) a layer made of a thermoplastic molding composition selected from a polyolefin molding composition and a fluoropolymer molding composition and II) a layer made of a polyamide molding composition, wherein not only the polyamide molding composition but also the molding composition of the layer according to I) in essence comprises no blend component which is composed of another polymer and which has disperse distribution in the molding composition.
