Problems solved by technology

Therefore, it is no longer homogeneous and the mechanical properties of the structure are not uniform
[0029] In theory, a diabolo-shaped and / or roll assembly made of flexible material could improve the situation, but these configurations also create offsets, do not accommodate diameter changes or are not compatible with softening strips. required high temperature

Embodiment Construction

[0077] In the following, the expressions "outer (outer, outer)" and "inner (inner, inner)" refer to an axis radially farther from the flexible tube and an axis radially closer to the flexible tube, respectively.

[0078] The expressions "front" and "rear" are to be understood axially with respect to the axis AA' of the tube, the expression "front" is to be understood as relatively farther from the middle of the tube and closer to one end thereof, the expression "rear" is to be understood as Relatively closer to the middle of the tube and farther from one end thereof. The middle of the tube refers to the point of the tube equidistant from the ends of the tube.

[0079] figure 1 Shown is the use of a manufacturing facility 11 according to the invention (at figure 2 Schematically shown in ) the first flexible tube 10 made.

[0080] Flexible tubing 10 includes figure 1 The middle section 12 is shown in the middle. The flexible tube includes an end end piece (not shown) at ea...

Abstract

Disclosed are a device for compacting a tubular structure, an associated installation and a method. The device (128) comprises a compaction roller assembly (150) supported by a support member, said roller assembly (150) comprising: a straight central shaft (160) having a longitudinal axis (B-B'); and a plurality of compaction rollers (162), mounted parallel to each other about the central shaft (160), each compaction roller (162) having a peripheral surface which is rotatable about the central shaft (160) about a roller axis (C-C'). The longitudinal axis (B-B') of the central shaft (160) is parallel to the central axis of the support member. Each roller axis (C-C') is inclined at a non-zero angle (alpha) of inclination with respect to the longitudinal axis (B-B') of the central shaft (160).

Description

technical field [0001] The invention relates to a compacting device for compacting a tubular structure, the compacting device comprising: [0002] - a support element defining a channel for the passage of a cylindrical surface for receiving the tubular structure, the channel having a central axis intended to be coaxial with the cylindrical surface, the support element and the cylindrical surface being mounted for rotation relative to each other about the central axis ; [0003] - at least one pinch roller assembly supported by the support element, the pinch roller assembly comprising: [0004] * Straight central axis with longitudinal axis; [0005] * A plurality of pinch rollers mounted parallel to one another about a central axis, each pinch roller having a peripheral surface that rotates about a roller axis about the central axis. [0006] Tubular structures are, for example, composite layers of flexible tubing for transporting fluids through bodies of water. Backgroun...
