    • The invention relates to an unbonded flexible pipe for subsea transportation of fluids. The pipe has a length and comprises a tubular inner sealing sheath defining a bore and an axis of the pipe. In a pipe length section it comprises a second sealing sheath surrounding the inner sealing sheath and forming an annulus between the inner sealing sheath and the second sealing sheath. The annulus provides a primary maintaining passage along the length of the pipe length section with a first and a second end. The pipe comprises at least one secondary maintaining passage along the length of the pipe with a first and a second end. The secondary maintaining passage is arranged with an axial distance which is larger than the axial distance of the inner sealing sheath.
    • 本发明涉及一种用于海底输送流体的无粘合柔性管。 该管具有长度并且包括限定孔和管的轴线的管状内密封护套。 在管道长度部分中,它包括围绕内部密封护套的第二密封护套并且在内部密封护套和第二密封护套之间形成环形空间。 环形空间沿着管长度段的长度提供具有第一和第二端的初级保持通道。 管道包括具有第一和第二端的沿着管的长度的至少一个次级保持通道。 副保持通道的轴向距离大于内密封护套的轴向距离。

    • Flexible, armored pipes and methods of using the same are disclosed. In an exemplary embodiment, the flexible, armored pipe includes an inner liner which is surrounded by a pressure armor. The inner liner may be built-up by joining together profiles that have a number of recesses. In one embodiment, the profiles are configured as K-profiles, which have recesses that are arranged in adjoining surfaces of the profile. When the profiles are brought together, the recesses form a cavity in which a locking element can be inserted, the function of which is to prevent displacement of the K-profiles at right-angles to the axial direction of the pipe when exposed to axial, compressive forces. The locking element can be I-shaped, circular or configured as a wire with a C-shaped cross-section. The locking element can also be made either of a rigid or an elastic, deformable material. With a C-shaped locking element, the whole of the cavity, which is formed by the recesses, is not filled out. A channel is thereby formed through which undesired fluids can be led away or through which cleaning fluids can be introduced.
    • 公开了柔性铠装管及其使用方法。 在示例性实施例中,柔性铠装管包括被压力铠装包围的内衬。 内衬可以通过将具有多个凹部的轮廓接合在一起而构成。 在一个实施例中,轮廓被配置为K型材,其具有布置在轮廓的相邻表面中的凹部。 当型材被接合在一起时,凹槽形成一个可以插入锁定元件的空腔,其功能是防止K型材在暴露于轴向时垂直于管道轴向移动, 压缩力。 锁定元件可以是I形,圆形或配置为具有C形横截面的线。 锁定元件也可以由刚性或弹性可变形的材料制成。 通过C形锁定元件,由凹部形成的整个空腔未被填充。 由此形成通道,通过该通道可以将不期望的流体引出或通过该通道可以引入清洁流体。
