Abstract: A flexible pipe of multilayer structure which comprises the following layers, from the inside to the outside: an interior lining; an inner reinforcement layer; a layer of molded electrically conductive plastic; an outer reinforcement layer; and an exterior sheath. The electrically conductive plastic layer is in electrical contact with the two reinforcement layers, and the two reinforcement layers can be connected to a source of electrical current. It is thus possible to achieve efficient heating of the pipe, and it can therefore be used for conveying oil in cold regions.
Abstract translation: 一种多层结构的柔性管，其包括从内到外的以下层：内衬; 内部加强层; 一层模塑导电塑料; 外加强层; 和外护套。 导电塑料层与两个加强层电接触，并且两个加强层可以连接到电流源。 因此，可以实现管道的有效加热，因此可以用于在寒冷地区输送油。

Abstract: In a method for the introduction of an inliner into a pipe or a pipeline, where the external diameter of the inliner is greater than the internal diameter of the pipe or of the pipeline, and where the action of an external force is used to reduce the cross section of the inliner prior to the introduction, the inliner is composed of a polyamide moulding composition which comprises at least 50% by weight of polyamide which is not PA11. The recovery behaviour of said polyamides is similar to that of polyethylene usually used for this purpose.
