The invention concerns a pipeline 1, in particular a pipeline 1 for fuel systems in aircraft, including an inner pipe 6 and an outer pipe 4 surrounding the inner pipe. In accordance with the invention, the inner pipe 6 is made of a metal material and/or, at least in portions, of a synthetic material and, at least in curved portions 5 of the pipeline 1, the outer pipe 4 is made of a synthetic material. Due to the fact that the outer pipe 4 is made of a synthetic material, a significant weight reduction can be accomplished in comparison to conventional coaxial pipelines, which are made entirely of a metal material and which, due to manufacturing reasons, require a larger number of flange joints 2 and 3 in longer curved pipeline portions. The invention also concerns a method for manufacturing such a pipeline 1, in particular a pipeline 1 for fuel systems in aircraft. |
