| 摘要 |
The invention relates to a subsea flexible pipe, the said flexible pipe comprising an internal sealing sheath (18), at least one tensile pressure armour layer (14, 16) wound around the said internal sealing sheath, a retaining layer (12) comprising at least one reinforcing strip (34), the said reinforcing strip comprising filamentary strands (36) directed substantially longitudinally, the said filamentary strands (36) comprising polymer fibres (38); according to the invention, the said polymer fibres have, at room temperature, an elastic modulus in excess of 55 GPa so that the said reinforcing strip is able to prevent the radial expansion of the said armour layer, when the said armour layer experiences radial force; and the said polymer fibres furthermore have an elongation at break in excess of 4% such that the said reinforcing strip is able to undergo deformation without breaking. |
