Abstract:
A cover including an elongate body, capable of being applied to be facing an outer surface of the pipe, and at least one longitudinal interaction element for interacting with the pipe, supported by the elongate body. The elongate body is reversibly deformable under the effect of its own weight, the elongate body having a length of more than 10 m. The cover treats solid build-ups within a fluid-transport pipe in a simple, straightforward and inexpensive manner.
Abstract:
The coupling includes a rigid inner shell (60) and an electric connecting line (68A, 68B), designed to heat a fluid flowing in the inner shell (60). The coupling (10) includes a rigid outer shell (62) positioned around the inner shell (60), the outer shell (62) and the inner shell (60) delimiting an intermediate space (64) between them containing the electric line (68A, 68B) and a thermally insulating layer (66) positioned in the intermediate space (64).
Abstract:
A method for assembling a rigid pipe intended to be placed in a body of water, the rigid pipe including a metallic inner tube, a thermally insulating insulation jacket formed from an assembly of insulating parts and an outer layer. The method includes the steps of providing the metallic inner tube, forming the insulation jacket, and forming the outer layer around the insulation jacket. The method includes a step for providing a plurality of helical insulating parts and a step of mounting the helical insulating parts around the inner tube in order to form the insulation jacket.
Abstract:
A pipe (18) having an inner fluid confinement assembly (30) including a corrugated inner tube (40) having an axis (A-A′), a tensile armour (42) arranged around the inner tube (40) and a heat-insulating assembly (44) arranged around the tensile armour (42). The pipe includes a ballast assembly (32) mounted around the inner assembly (30). The ballast assembly (32) includes a plurality of collars (70A) mounted externally on the inner assembly (30) to form a support layer (70), at least one outer armour (72) and at least one ballast ring (74A) engaged around the outer armour (72).

Abstract:
A coupling that includes a rigid inner shell, a rigid outer shell positioned around the inner shell to define an intermediate space that contains an electric line and a thermally insulating layer, and an electric connecting line for heating fluid that flows in the inner shell.
Abstract:
The pipe includes at least one tubular sheath delimiting a passage for circulation of the abrasive material, at least one tensile armor layer externally positioned with respect to the tubular sheath, the armor layer including a plurality of filiform armor elements. It further includes a protective internal layer positioned inside the tubular sheath in the circulation passage, the protective internal layer including an elastomeric matrix and a longitudinal reinforcement assembly embedded in the matrix.
Abstract:
A device comprises an assembly for attaching to and moving on the production line. The attachment and movement assembly comprises at least two clamps that can be actuated selectively to clamp the production line, the attachment and movement assembly comprising an active mechanism for moving the clamps longitudinally relative to each other. The attachment and movement assembly comprises a tilting mechanism for tilting the clamps relative to each other, between a position in which they are parallel to each other and a position in which they are tilted with respect to each other. The tilting mechanism comprises a flexion bar capable of switching from a straight configuration in the parallel position of the clamps to a curved configuration in the tilted position of the clamps.
Abstract:
A clamp comprises a plurality of pads; a belt for clamping the pads that is maneuverable between an unclamped configuration and a configuration clamping the pads against the production line; a clamping actuator for the clamp, mounted on a first point of the clamp, the clamping actuator having a grasping member for a second point of the clamp, the grasping member being movable between a deployed position and a retracted position moving the second point towards the first point. The spacing-apart mechanism is able to move the grasping member between a spaced-apart configuration of the second point in the deployed position of the grasping member and a grasping configuration in an intermediate position between the deployed position and the retracted position.
Abstract:
A method including the following steps: assembling sections of metal tube end-to-end so as to form an inner tube having a continuous passage for circulation of fluid; positioning a thermally insulating sleeve around each section of metal tube, the thermally insulating sleeve comprising at least one longitudinal groove; introducing a continuous functional line into at least two longitudinal grooves in at least two adjacent sections of tube; and filling in each longitudinal groove in order to cover the continuous functional line.
