| 摘要 |
The present invention relates to a flexible tubular pipe for carrying fluids under pressure containing H2S and to a method for designing such a flexible pipe. The pipe includes a body (7), an internal sealing sheath (8), at least one steel armouring layer (9,10) withstanding the stresses induced by the inside/outside pressure difference, and at least one traction-resisting steel armouring layer (11, 12) spirally wound at an angle less than 45° in relation to the axis of the pipe. In this pipe, at least the armouring layer withstanding the stresses induced by the inside/outside pressure difference is made of a determined steel meeting H2S resistance criteria, and at least the traction-resisting armouring layer is made from steel wires that do not meet H2S resistance criteria. |
