摘要： The invention relates to a method for monitoring the thermomechanical behaviour of a subsea pipe (2) carrying pressurised fluids and produced by assembling unitary pipe elements (4), the method comprising a step of determining a mechanical signature specific to each unitary pipe element, consisting in using a measuring cable (16) provided with a fibre optic sensor using Brillouin backscattering to measure the deformations in each unitary pipe element when it is subjected, while ashore, to different mechanical stresses of predetermined directions and intensities, and to establish a stiffness matrix associated with the mechanical signature of each unitary pipe element; a step of determining a thermal signature specific to each unitary pipe element by measuring the temperature changes in said unitary pipe element when it is subjected, while ashore, to different electrical heating power values, and establishing a thermal transfer function associated with said thermal signature of each unitary pipe element; and a monitoring step consisting in recovering the variations of the optical signal injected in the sensors when the pipe is in service, and determining the changes in the mechanical and thermal signatures of each unitary pipe element.

摘要： The invention relates to a method for monitoring the mechanical behaviour of an subsea pipe (2) carrying pressurised fluids and produced by assembling unitary pipe elements (4), the method comprising a mechanical calibration step that consists in using a measuring cable provided with an optical fibre sensor to measure the deformations in each unitary pipe element when subjected, while ashore, to different mechanical stresses of predetermined directions and intensities, and, on the basis of these measurements, establishing the mechanical signature of each unitary pipe element; and a monitoring step consisting in using a measuring cable (18) provided with a fibre optic sensor using Brillouin backscattering and positioned in the shape of a helix with a constant pitch (p) on each unitary pipe element, the direction of the pitch of the helix alternating in two adjacent unitary pipe elements, to recover the variations of the optical signal injected in the sensors when the pipe is in service, and, from the variations of the signal and the mechanical signature of each unitary pipe element, determining the stresses that each unitary pipe element is subjected to.

摘要： The invention relates to a pipe (1) comprising at least two pipe elements (11, 12) provided with a plastic internal liner (2) and assembled end to end. The ends of the two pipe elements are soldered (5) to each other and the ends of the plastic internal liners (2) of each of the pipe elements are connected by means of a tubular connection sleeve (3) which consists of an anti-corrosive material and co-operates with the ends (2a, 2b) of the liner by engagement by means of a notched surface (32). The ends of the liner (2) have a reduced thickness (2a, 2b) and are locked onto the steel wall of the pipe by adhesion (4a, 4b).
