Patent number: 10113671Abstract: A process for the production of a pipe comprising: an interior surface having a shape; and a thermoplastic inliner is provided. The process comprises: introducing the thermoplastic inliner into the interior of the pipe; heating the pipe from the outside to a temperature higher than a crystallite melting point (Tm) of a molding composition of an exterior surface of the inliner; expanding the inliner radially in the pipe so that an exterior surface of the inliner assumes the shape of the interior surface of the pipe; and cooling the inliner; wherein a cross section of the inliner is optionally reduced through exposure to an exterior force prior to being introduced into the pipe. Relative movements between carrier pipe and inliner are thus prevented; the risk of collapse of the inliner is moreover low. The pipe is used for the production of a laid pipeline.Type: GrantFiled: March 25, 2014Date of Patent: October 30, 2018Assignee: EVONIK DEGUSSA GmbHInventors: Juergen Franosch, Jan Berger, Andreas Dowe, Marco Gensheimer, Uwe Kannengiesser
