Abstract: An armoured flexible pipe has an inner liner (3) surrounded by a pressure armour (5, 6) that is surrounded by a tensile armour (7, 8). The pressure armour (5, 6) is constructed from a number of profiles (5, 6, 10, 11, 12, 14, 14a, 14b, 14c) which may engage with each other. In order to obtain optimum functionality, the profiles are shaped as X profiles (14, 14a, 14b, 14c) which are kept together with another type of profile, e.g. C or T type profiles. In one embodiment, the X profiles have an open channel (17). In this way gas or liquid, such as rinsing fluid, may be pumped through the armour layer, from one end of the pipe to the other end. In particular, the armoured flexible pipe is useful for conveying fluids such as water, ammonia, hydrocarbons, etc.

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.

Abstract: Flexible, armored pipes and methods of using the same are disclosed. In an exemplary embodiment, the flexible, armored pipe includes an inner liner which is surrounded by a pressure armor. The inner liner may be built-up by joining together profiles that have a number of recesses. In one embodiment, the profiles are configured as K-profiles, which have recesses that are arranged in adjoining surfaces of the profile. When the profiles are brought together, the recesses form a cavity in which a locking element can be inserted, the function of which is to prevent displacement of the K-profiles at right-angles to the axial direction of the pipe when exposed to axial, compressive forces. The locking element can be I-shaped, circular or configured as a wire with a C-shaped cross-section. The locking element can also be made either of a rigid or an elastic, deformable material. With a C-shaped locking element, the whole of the cavity, which is formed by the recesses, is not filled out.

According to the invention, the profiles are configured as K-profiles (10, 16, 17), which have recesses (10a, 10b, 10c, 10d), which are arranged in adjoining surfaces of the profile. When the profiles are brought together, the recesses form a cavity in which a locking element (12, 14, 18) can be inserted, the function of which is to prevent displacement of the K-profiles at right-angles to the axial direction of the pipe when this is exposed to axial, compressive forces.
