| 摘要 |
The invention relates to a flexible pipe for transporting fluid, which includes: an inner polymer sheath (20) defining an inner passage (16) for flowing a fluid transported by the pipe; a first intermediate polymer sheath, arranged outside the inner sheath (20), the first intermediate sheath (22) and the inner sheath (20) defining therebetween a first annular space (28); at least one layer of inner reinforcements (34, 35), arranged inside the first annular space (28); at least one outer layer arranged outside the first intermediate sheath (22). The flexible pipe comprises a second intermediate polymer sheath (26), inserted between the first intermediate sheath (22) and the outer layer, the first intermediate sheath (22) and the second intermediate sheath (26) defining therebetween an annular test space (30) for testing the integrity of the first intermediate sheath (22). |
