A reinforced flexible pipeline (1), which has an inner liner (3) whose inner side engages an inner reinforcement layer (2) that may be formed by a so- called carcass, and on whose outer side at least a strength-imparting reinforcement layer (4, 5, 6, 7) is provided, has an additional barrier laye r (9, 10, 11) which is arranged between the inner liner and the inner reinforcement layer. The additional barrier layer is thermally insulating and/or chemically protecting. The additional barrier layer may be formed as a tape (9) which is wound around the inner reinforcement layer, or may be composed of locking profiles (10, 11) which are wound around the flexible pipeline in a helix. The additional barrier layer (9, 10, 11) may be made completely or partly of a polymer which may be thermoplastic, or is cross- linked completely or partly. Hereby, the pipe may be protected against temperatures above e.g. 13~C and may also be protected against attacks from methanol that contains water. By constructing the additional barrier layer o f profiles it is additionally ensured that it can transfer great compressive forces to the inner reinforcement layer, without any risk of the liner being caused to float since it is supported evenly by the additional barrier layer .
