Patent number: 9982410Abstract: 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: GrantFiled: April 10, 2012Date of Patent: May 29, 2018Assignees: Evonik Degussa GmbH, Salzgitter Mannesmann Line Pipe GmbHInventors: Markus Hartmann, Claudia Behrens, Reinhard Beuth, Joern Winkels, Hans-Juergen Kocks, Konrad Thannbichler

Patent number: 9057466Abstract: A molding composition which comprises at least 50% by weight of the following constituents: a) from 0 to 99 parts by weight of polyamide, and b) from 1 to 100 parts by weight of polyamide elastomer, selected from the group of polyetheresteramide and polyetheramide, where the total of the parts by weight is 100 and where the molding composition comprises from 0 to 9% by weight of plasticizer, is used for the production of a molding for contact with a supercritical medium, and preferably for the production of an inner thermoplastics layer in a flexible pipe or rigid pipe, in which a supercritical medium is conveyed. Low or zero plasticizer content eliminates any significant occurrence of problems such as increased stiffness and longitudinal shrinkage.Type: GrantFiled: October 7, 2009Date of Patent: June 16, 2015Assignee: Evonik Degussa GmbHInventors: Andreas Dowe, Reinhard Beuth, Franz-Erich Baumann
