Abstract
A subsea flexible pipe, including an internal sealing sheath (), at least one tensile pressure armor layer () wound around the internal sealing sheath, a retaining layer () having at least one reinforcing strip (), the reinforcing strip having filamentary strands () directed substantially longitudinally. The filamentary strands () having polymer fibers (). The polymer fibers have, at room temperature, an elastic modulus in excess of 55 GPa so that the reinforcing strip is able to prevent radial expansion of the armor layer, when the armor layer experiences radial force; and the polymer fibers furthermore have an elongation at break in excess of 4% such that the reinforcing strip is able to undergo deformation without breaking.
