The current invention concerns a filament-wound liner-free GRP pipe. The reinforcement filaments comprise one or more spiral fibre windings wrapped in a first direction, one or more spiral fibre cross windings wrapped in a second direction and one or more longitudinal fibre rovings, the longitudinal fibre rovings extending along the length of the pipe in the rigide sides of the pipes. It also concerns a process for manufacturing the same via a filament winding process. Furthermore, it concerns the production line and the mandrel and winding stations used therein. Finally, it concerns the use of the new pipe, for offshore and onshore applications, in particular as flexible riser pipe. |
