摘要： The invention relates to an unbonded flexible pipe for sub sea transportation of fluids. The pipe has a length and comprises a tubular inner sealing sheath (2) defining a bore and an axis (8) of the pipe. In a pipe length section it comprises a second sealing sheath (9) surrounding the inner sealing sheath (2) 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 (5) 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 (2). The first end of one of the primary and the secondary maintaining passages is arranged as an input end for a maintaining fluid and the first end of the other of the primary and the secondary maintaining passages is arranged as an outflow end for the maintaining fluid, and the primary and the secondary maintaining passages are in fluidic connection with each other at their second ends to provide a pathway for the maintaining fluid. The pathway for a maintaining fluid makes it possible in a simple and effective manner to keep the corrosion of elements - such as armouring elements in the annulus - relativly low, and accordingly the duration of the unbonded flexible pipe can thereby be increased.
摘要翻译：本发明涉及用于海底输送流体的无粘合柔性管。管道具有长度并且包括限定孔的管状内部密封护套（2）和管道的轴线（8）。在管道长度部分中，其包括围绕内部密封护套（2）的第二密封护套（9），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。该管道包括沿管道长度的第一和第二端部的至少一个次级保持通道（5）。副保持通道的轴向距离大于内密封护套（2）的轴向距离。第一和第二维持通道中的一个的第一端被布置为用于维持流体的输入端，并且另一个主维护通道和辅助保持通道的第一端被布置为用于维持流体的流出端，以及初级和次级保持通道在其第二端处彼此流体连接以提供维持流体的通路。用于维持流体的路径使得以简单有效的方式保持元件的腐蚀（例如环形空间中的铠装元件）相对较低，从而可以增加未粘合的柔性管的持续时间。
