| 摘要 |
The invention concerns a flexible pipeline with multiple pipes, adapted for hydrocarbon transport, said pipeline comprising a flexible core element (8) inside which flows said hydrocarbon, an outer sheath (26) around said flexible core element (18) and at least one peripheral steel alloy pipe (22) extending longitudinally in an annular space (28) located between said outer sheath (26) and said flexible core element (18), said annular space (28) further comprising metal elements (40, 42) in contact with an aqueous medium containing oxygen, said metal elements being susceptible to being oxidized by fixing oxygen. The invention is characterized in that said oxidizable metal elements (40, 42) and said peripheral pipe (22) are maintained mutually spaced apart to be electrically decoupled. |
