Armoured, flexible pipe and use of same

Abstract

A flexible armored pipe, which comprises an inner liner, which is surrounded by a pressure armor, is built up by the joining together of profiles, which have a number of recesses. According to the invention, the profiles are configured as K-profiles (10, 16, 17), which have recesses (10a, 10b, 10c, 10d), which are arranged in adjoining surfaces of the profile. When the profiles are brought together, the recesses form a cavity in which a locking element (12, 14, 18) 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 this is exposed to axial, compressive forces. The locking element can be I-shaped (14), be circular or be configured as a wire (18) 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 hereby formed through which undesired fluids can be led away or through which cleaning fluids can be introduced.
