A composite armour for a flexible pipe includes a composite profile and a reinforcement tape. The composite profile includes longitudinally oriented reinforcement fibres embedded in a polymer matrix. The reinforcement tape includes a woven tape comprising fibres impregnated with a polymer material, in such a way that the weft thread of the reinforcement tape is orthogonal to the longitudinal direction of the profile, and the warp thread is parallel to the longitudinal direction of the profile.

Armour for flexible pipe comprising a one-way composite profile section and a reinforcing strip

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

Flexible pipe with layers of metal armour and layers of composite armour

A pipe () for conveying a fluid, including an inner sheath (), at least one layer () of inner armors, arranged outside the inner sheath () and an outer protection sheath (), positioned outside each layer () of inner armors. It includes an inner fluid, received between the inner sheath () and the outer sheath (). The pipe includes an intermediate polymer sheath (), interposed between the inner sheath () and the outer sheath (), the intermediate sheath () and the inner sheath () delimiting an inner annular space () between them for receiving the inner fluid. The inner fluid is confined in the inner annular space () at a pressure above 50 bars.
