TEMPERATURE-CONTROLLABLE PIPE FOR OFFSHORE APPLICATIONS

摘要

The present invention relates to a temperature-controllable, flexible pipe of multilayer structure with unbonded layers. A flexible pipe of multilayer structure which comprises the following layers, from the inside to the outside: an interior lining, at least two reinforcement layers made of metal, and an exterior sheath, has two reinforcement layers between which there is a layer made of an electrically conductive plastics moulding composition which is in electrical contact with the two reinforcement layers. 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.
