Definitions

  • the present invention relates to a device for continuously producing a spiral tubular structure in stapled strip.
  • the applicant company has developed and markets flexible tubular pipes with high mechanical properties, in particular with regard to tensile strength and pressure resistance, for various applications, and in particular for the exploitation of seabed oil. exerted, both from the outside on the pipe, and from the inside by the products, in particular the hydrocarbons, transported.
  • Such conduits generally comprise at least one layer formed of a tubular structure of stapled strip wound in a helix, the turns having a section substantially in the form of an S or Z allowing their mutual attachment.
  • Such a tubular structure is thus used in pipes of the “rough bore” type for producing the internal carcass of the pipe which then constitutes a vault for the latter.
  • connection is also made, for certain applications, to use at least one other tubular layer formed of a spiral structure of stapled strip forming a hoop intended to reinforce the resistance of the pipe to internal and external pressures.
  • the stapled strip fret or frets are usually separated from the inner vault by a sheath made of thermoplastic material.
  • the pipe is generally supplemented by one or more layers of armouring son and comprises an outer thermoplastic sheath for sealing and protecting against corrosion.
  • fret bore in which the internal layer is a thermoplastic sheet, one or more frets are also used, each formed of a spiral structure in stapled strip.
  • Spiral tubular structures in stapled strip also find applications in other types of flexible or rigid pipes.
  • the coil must therefore be mounted for this purpose in a cage capable of rotating around the longitudinal axis, means being further provided for rotating the coil in the cage around a transverse axis. It is also necessary to rotate the extractor mechanism around the same longitudinal axis, which is then mounted in a rotating cage which must be driven in synachronism with the cage containing the take-up reel.
  • a device comprising on the one hand a circular plate rotating about a horizontal axis coinciding with the longitudinal axis of the tubular structure to be formed, comprising, on a same side, a support member for a flat strip supply reel, a set of motorized profiling rollers for driving the strip and imparting to it a section substantially in the form of an S or Z, means for guiding the strip between the supply coil and the set of profiling rollers, a tubular mandrel mounted coaxially on said plate in the vicinity of the center thereof and on the other hand a longitudinal drive mechanism of the formed tubular structure, arranged downstream of said turntable to drive the structure formed towards a take-up reel.
  • the present invention proposes to provide a device avoiding these drawbacks and allowing to produce tubular structures of easily adjustable diameter, without a central core or around a flexible or rigid central core.
  • the device according to the invention is characterized by the fact that it comprises, on a plate, a plurality of pressure rollers mounted idly, adjustable in position around the mandrel and distributed around a mandrel near its axial end to ensure application on the latter of the profiled strip leaving the profiling wheels as well as the stapling of the successive turns and the extraction of the stapled structure formed, the mandrel being driven in rotation with an opposite speed and preferably less than the speed of rotation of the plate, for example a speed of the order of 10% thereof allowing the mandrel to slide relative to the strip during winding in order to avoid seizing thereof.
  • the tubular product formed does not rotate on itself, this being obtained in practice by adjusting the speed of rotation of the profiling wheels as a function of the speed of rotation of the circular plate and the diameter of the tubular structure. formed.
  • Diameter changes can be easily made by simply changing the mandrel and moving the crazy pressure rollers around it.
  • the device further comprises, between the plate and the drive mechanism, a set of support elements, such as V-shaped pads, resting on the periphery of the structure formed. so as to tighten the turns.
  • a set of support elements such as V-shaped pads
  • Such a set of support elements is particularly advantageous when the spiraling of the stapled strip structure takes place around a core because such an assembly allows the tightening of the turns to the diameter of the core.
  • the core is then fed through an axial opening provided in the plate and through an axial internal cavity of the mandrel. It is understood in this case that the core supply coil, when the latter is flexible, also does not need to be driven in rotation about the longitudinal axis since the core itself is not driven in rotation.
  • the set of support elements when provided, is mounted on a rotating frame animated with a speed of rotation greater than that of the plate.
  • the set of profiling rollers is mounted on a support articulated on the plate and tiltable relative thereto, the inclination of the support determining the angle of winding of the turns of the strip of the structure. formed.
  • the drive mechanism can be of any suitable type, for example with motorized rollers or of the trichenilla type, this mechanism helping to immobilize the formed structure in rotation.
  • the device illustrated in the drawing comprises a circular plate 1 driven in rotation in the direction shown diagrammatically by the arrow in FIG. 2, around a horizontal axis 2 by drive means not shown.
  • the plate 1 On one of its faces, the plate 1 has different components which will be described below.
  • the assembly 8 comprises two blocks having, in the example illustrated each, six motorized profiling wheels, the blocks being separable from each other as shown diagrammatically by the arrows in FIG. 2.
  • the assembly 8 can be displaced by translation in the plane of the plate so that the strip exiting from the set of rollers is disposed tangentially with respect to the external surface of the mandrel 10.
  • the set of profiling rollers 8 is also mounted, as can be seen best in Figures 1 and 3 on a support 9 articulated on the plate 1 and tiltable relative thereto by an angle a variable, the inclination of the support 9 relative to the plate 1 determining the winding angle strip turns formed as best seen on examining Figure 3.
  • a tubular mandrel 10 around which the spiraling of the strip takes place.
  • the mandrel 10 is driven in rotation, by drive means not shown, so as to be driven by an opposite speed of rotation and lower than the speed of rotation of the plate, this speed possibly being for example of the order of 10% of the speed of the platter.
  • the profiled strip exiting from the set of knurls 8 is applied to the periphery of the mandrel by a plurality of idle pressing rollers 11 distributed around the mandrel 10, ensuring the stapling of the successive turns formed, their tightening and extracting them from the mandrel.
  • the spiral tubular structure in stapled strip 12, thus formed, is extracted by a longitudinal drive mechanism, of the trichenilla type 13 making it possible to contribute to the immobili rotation of the structure formed and the adjustment of the winding pitch.
  • the device comprises, at the edge, between the plate 1 and the drive mechanism 13, a set of support elements 14 made up of V-shaped pads, 15, constrained by springs. 16 and mounted on a frame 17 driven in rotation, by means not shown, about the axis 2.
  • the speed of rotation of the rotating frame 17 is greater than the speed of rotation of the plate 1.
  • the device in use has been shown to produce a carcass of stapled strip in the form of a carcass without an inner core.
  • the first turns are wound on the mandrel, then once the turns have reached the drive mechanism 13, the latter pulls the formed carcass at a speed proportional to the speed of rotation of the plate 2 allowing the continuous production of a spiral tubular structure in stapled strip which is wound around a take-up reel, not shown, arranged downstream of the drive mechanism.
