A flexible, polymer, composite tube (1) adapted for transport of fluids such as hydrocarbons, e.g. oil and/or gas, and flexible enough to be coiled with a curvature radius as short as approximately 20 times its outer diameter. The flexible riser (1) comprises the following structural elements: an inner liner (2) of thermoplastic material, an intermediate reinforced, polymer, multi layer component (3), and an outer thermoplastic liner (4). The inner liner (2) is continuously bonded to the intermediate, multi layer component (3), which again is continuously bonded to the outer liner (4). A method for manufacturing the flexible tube (1) by welding or gluing is also described.
L'invention pore sur un tube (1) composite, polymère, flexible adapté au transport des fluides tels que des hydrocarbures, pétrole et/ou gaz, et qui est suffisamment flexible pour s'enrouler, son rayon de courbure étant approximativement 20 fois aussi court que son diamètre externe. Le tube ascenseur (1) flexible comprend les éléments structuraux suivants : un revêtement (2) intérieur de matière thermoplastique, un composant (3) intermédiaire multi-couche, polymère, renforcé et un revêtement (4) thermoplastique extérieur. Le revêtement (2) intérieur est collé en continu au composant (3) intermédiaire, multi-couche, lui-même collé au revêtement (4) extérieur. L'invention porte également sur un procédé de fabrication du tube (1) flexible par soudage ou collage.
