Abstract: The present invention relates to a flexible pipe comprising a mechanical reinforcement element (4) and a pressure sheath. Mechanical reinforcement element (4) comprises at least one metallic tensile armour layer (6) and at least one composite tensile armour layer (7). Composite tensile armour layer (7) is arranged outside metallic tensile armour layer (6). Separation means (8) are provided to separate composite tensile armours (7), while maintaining a radial clearance and a circumferential clearance for composite tensile armours (7).

Abstract: The present disclosure relates to a flexible tubular pipe (1) of the unbonded type and including, from the inside to the outside, an internal carcass (2), first and second polymeric sheaths (3, 4), at least one tensile armor layer (6, 7) and a polymeric sealing sheath (8) and also at each of its ends, a connecting endpiece (10) comprising i.a., a tubular sleeve (15). The tubular sleeve (15) of a first endpiece (10) includes means (30, 31, 32) for draining the gases from the gap (25) between the sheaths (3, 4) towards the outside of the pipe (1) and the tubular sleeve of the second endpiece (10) including means for draining the gases from the gap (25) between two sheaths (3, 4) towards the outside or towards the inside of the pipe (1).

Abstract: A method for manufacturing a flexible tubular underwater pipe (10): A leakproof tubular structure (12, 14, 16) is covered with at least one layer (18, 20) of armor wires. At least one continuous longitudinal element made of a deformable material is wound in a helix with short pitch around the layer (18, 20) of armor wires to form a holding layer 24. The at least one longitudinal element is wound under longitudinal tension T0 so as to stretch its deformable material according to a relative elongation corresponding to a tensile stress ?0 less than the elastic limit value ?E of the deformable material, and the elastic limit value ?E corresponds to a tensile stress beyond which the deformation of the material is irreversible.

Abstract: A method for the drainage of permeate gases from a flexible tubular pipe and a pipe embodied for carrying out the method. The pipe comprises at least one inner pressure sleeve, for the transport of hydrocarbons, which contain permeate gases which diffuse across the wall of the inner pressure sleeve. The pipe has an outer sleeve and several reinforcement layers, arranged in an annular zone between the outer sleeve and the inner pressure sleeve. The annular zone has transport ducts in which the permeate gases can circulate towards the removal. The method comprises a forced circulation of the permeate gases in the annular zone through the transport ducts towards the removal.
