ABSTRACT:
A flexible, armoured pipe has an impermeable inner liner (3), which is surrounded by at least two reinforcement layers (5, 6, 7, 8). Between the reinforcement layers an impermeable membrane (10) is provided, which ensures that fluids do not permeate into the inner reinforcement layers (5, 6) from the pipe's outer reinforcement layers (7, 8). The outer layers are not isolated from influence from the surrounding environment. Moreover, the outer layers (traction reinforcement layers) are protected against the damaging effect of gases, which are diffused out through the flexible pipe. On the outside of the outer traction reinforcement layers (7, 8) a layer (11) can be applied, which is easily permeated by the surroundings, and which protects the traction reinforcement layer against mechanical influences. In this way it is ensured that the pressure reinforcement can absorb forces both from inner as well as outer pressure.
