摘要： 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 layer (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 of 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.

摘要： For use in the manufacture of reinforcement layers for flexible pipes which are capable of absorbing compressive or tensile forces, and which are used for the transport of oil and gas, a thermoplastic material is applied to a strength-imparting layer. The strength-imparting layers are reeled on reels, and following unreeling they are laminated by application of heat and in direct continuation applied to the flexible pipe. The strength-imparting layer expediently consists of a polymer which is reinforced with at least 20% by volume of fibres. The thermoplastic material is of a reversible type, i.e. it may change from being relatively soft, but non-sticky by changes in temperature. The use of the method according to the invention allows manufacture of very strong reinforcements for flexible pipes which cannot be manufactured using a solid material, such as steel, since high preforming bending forces are required in the shaping. In addition, a reinforcement element is provided which is capable of resisting instantaneous shock loads as the thermoplastic material is protective.
