  • Use of a conduit pipe for producing a duct laid in water
    Patent number: 10072786
    Abstract: A metal conduit pipe, which is covered with an extruded layer made of polyamide molding compound, is used to produce a duct laid in water, wherein in the course of laying the duct, the coating is exposed to a shearing pressure load and/or a bending load due to laying method selected.
    Type: Grant
    Filed: January 20, 2010
    Date of Patent: September 11, 2018
    Assignees: Evonik Degussa GmbH, Salzgitter Mannesmann Line Pipe GmbH

  • 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

  • Method of producing an underground pipeline
    Patent number: 9574700
    Abstract: A pipeline laid trenchlessly and/or without a sand bed is produced using a metallic conduit which is encased with an extruded layer of a polyamide molding material. In this way, the durability of the outer shell required for trenchless laying techniques without a sand bed is ensured.
