| 摘要 |
A flexible lightweight high pressure pipe for riser or pipeline applications, especially offshore, comprising an internal liner (3), a first structural layer (4) applied to the internal liner, for absorbing pressure loads, one or more additional structural layers (5, 6) applied to the first structural layer (4), for absorbing axial and bending loads, and a fluid-tight external cover (7). Both the first structural layer (4) and the additional structural layers (5, 6) are manufactured from a lightweight composite material consisting of a fibre-reinforced matrix, the first structural layer (4) being a solid layer reinforced by long continuous fibres (8) extending around the pipe (1), and each of the additional structural layers (5, 6) consisting of a plurality of individual strips (11) reinforced by fibres extending essentially in the longitudinal direction of the strips, and which are wound around the pipe (1), but are not bonded to the adjacent strips (11) or to the layers (4, 7) above or below these. |
