Definitions

  • the present invention relates to a device for carrying out continuous tubular structure consisting of a helical winding from at least one wire with a large cross-section, in particular but not exclusively a non-self-stapling thread, delivered by a spool of thread and the if applicable (i.e. when it comes to using a non-self-stapling wire) at least one stapling wire supplied by a spool of stapling wire, device which will later be called a spiraling machine.
  • a device according to the preamble of claim 1 is known from document EP-A-0 494 299.
  • the plaintiff develops and markets for different applications, and in particular for the oil exploitation of seabed, flexible tubular conduits having characteristics high mechanical properties, in particular with regard to resistance to traction and resistance to the pressures exerted, both from outside the driven only from the inside, by products, in particular hydrocarbons, transported.
  • a spiraling machine suitable for these relatively flexible straps which includes a circular plate rotating around a horizontal axis coinciding with the longitudinal axis of the tubular structure to be formed and supporting, on a same face where the helical winding is committed, a strip supply reel, guide rollers, a set of profiling rollers and pressure rollers cooperating with a mandrel of commissioning to form the turns of the winding.
  • the same spiral is included in the second document, it being specified that one can use simultaneously two coils delivering either two self-stapling wires or one wire not self-stapling and an additional wire ensuring stapling by combination with the first wire.
  • a first variant of the device inspired by document US-A-4,783,980 is described, as well as a second variant, inspired by document US-A-4,895,011.
  • profiled strips are unwound from stationary power coils and come to be wound externally in turns around the turntable, the inner coil of this winding being taken up by a deflection roller to send the tapes to the commit point.
  • flexible tubular conduits comprising a metal reinforcing ply such as a carcass internal or a web ensuring resistance to internal or external pressure called a pressure vault, said reinforcing ply consisting of the helical winding of a self-stapling wire of the shaped wire type having a solid Z-shaped section, such as the wires known as name of "zeta”.
  • Documents FR-A-2 052 057 and FR-A-2 182 372 describe such windings, respectively of relatively thick wire wound at low pitch and flattened section wire wound at wide pitch, and the means of making them; these include in particular means for giving permanent saber blade deformation to the wire before winding.
  • Shaped wires affected by the techniques described in these two patents, and in the current state of the spiraling technique, have a thickness which is at most 10 mm or exceptionally 12 mm.
  • the self-stapling wires constituted by a strip of section typically in S or Z can give satisfaction up to a certain level of forces or constraints involved, it appeared that to achieve the carcases or pressure vaults of flexible pipes, especially those intended for a more difficult environment (for example very high internal pressure, very large water depth, very large hose diameter, high dynamic loads), we had to develop tubular structures produced by co-winding a non-wire self-stapling and an additional element responsible for hanging the turns not self-stapling wire neighbors.
  • the non self-stapling wire is advantageously a wire of the relatively thick form wire of section preferably full with raised parts, the section of the wire being advantageously in T or in U, and no longer simply a profiled strip in the case of a self-stapling S or Z shaped carcass or wire in the case of a pressure vault;
  • the complementary element, which thereafter will simply call stapling wire is for example in U, or can even be formed by a second wire identical in shape to the first but arranged upside down and wrapped around the first wire (straddling two whorls next to the first wire), if the hooking reliefs of the wire form are provided for this purpose.
  • the manufacture of the spiral structure is only touched; it just says that we can spiral the T-wire as in the case of the unstapled wire of a pressure vault complementary or fret (that is to say generally consisting of a ribbon); this is certainly possible for the section T-shaped wires relatively small whose relatively low stiffness allows a routing and winding of the wire without particular problems of guidance, bending, bending, etc. This is no longer true when the sections of the shaped wires are considerable and induce rigidity itself considerable thread.
  • the section thickness of the wires self-stapling steel Z used goes from 4.8mm to 10mm, or even exceptionally 12mm.
  • the non-self-stapling T-wires that are targeted specially the invention have a thickness of 12mm, 14mm, 16mm or beyond.
  • the invention provides a device for continuously performing a tubular structure constituted by a helical winding from at least at least one wire with a large cross-section, in particular a staplable wire, in particular a non-self-stapling wire, delivered by a coil of wire and the case if necessary at least one stapling wire delivered by a spool of stapling wire, comprising a motorized circular cage rotating around an axis horizontal with which the longitudinal axis of the tubular structure coincides, the tubular structure forming at a committing point located in the vicinity of the downstream face of the cage, and means for longitudinal drive and receiving said tubular structure, in which the wire spool and the case if necessary, the spool of stapling wire is shipped in rotation with the cage and the downstream face of the cage supports at least one linear tractor (i.e.
  • a traction means acting on a linear section of wire on board for driving the wire delivered from said spool of wire, interposed between said reel and the committing point of the structure.
  • a tractor has two parallel gripping antagonistic surfaces and is typically a two-track tensioner (known as a "double track"), or possibly a set of two opposite roller trains.
  • the purpose of the tractor is to pull, advantageously in the regulated manner which will be seen later, the wire which arrives from the upstream of the cage under a traction very high considering the sections of wire involved, and to restore it in part downstream under adequate traction, which can even be chosen zero, or even negative (compression).
  • the rollers mentioned higher are mainly bending rollers (single rollers with inside the wire loop downstream of the tractor) and in the case of the wire pushed, these are, except for the last support rollers, essentially guide rollers (double rollers framing the wire), it being understood that at the point of commissioning, there are always bending rollers and / or support also serving as bending in pushed wire.
  • a sensor for positioning is provided on the wire path between the tractor (the bichenille for example) and the decintring / guiding rollers to control the drive speed of the tractor so that the traction of the wire downstream of the tractor remains within a set range.
  • the cage has a central passage through which the hose passes to the periphery of which the shaping wire constituting the pressure vault.
  • the cage is integral on its upstream face with a coaxial tube which supports the wire spool (s) and the wire spool (s) stapling.
  • the cage then advantageously comprises openings of passage of the wire and the stapling wire from its upstream face to its downstream face.
  • the cage has on its downstream face at minus a platform inclined with respect to the latter for supporting the tractor and organs in contact with the wire interposed between the tractor and the point committing (namely in particular the guide rolls and / or bending), so that from its passage in the tractor, the wire is only deformed by simple bending, i.e. bending in a plane which is the osculating plane, to the exclusion of any other deformation such as twisting or bending on edge.
  • two sons and two tractors in particular two double-deckers corresponding, each carried by one of two inclined plates opposite, in two symmetrical configurations with respect to the axis of the machine.
  • two reels of stapling wire are also provided.
  • each tray has the shape of a crescent partially surrounding said tubular structure over at least 180 °, the ends of the two crescents interlocking so as to wrap the flexible in two symmetrical sectors preferably greater than or equal to 90 °.
  • the inclination of the plate or plates is adjustable, for example between 0 and 10 °, so that you can make windings for several possible helix angles, depending on the cross-section of the wires and the diameter of the tubular structure.
  • the onboard bichenilles conform to the invention make it possible to reduce the traction over the length of downstream wire to a reasonable value, controlled to stay within a given range, so as not to damage the hose (plastic sheath) on which winding is carried out, traction in the wire inducing a force crushing of the inner layers of the hose on which the thread.
  • the wire and the machine according to the present invention can be used without pre-bending on edge.
  • the inclination, preferably adjustable, trays carrying the bichenilles allows this winding without bending on edge, that is to say without imposing over plastic deformations on edge (saber blade deformations) detrimental to the correct winding committing point.
  • the cage is driven by a powerful motor element (by example of the order of 250kW).
  • a powerful motor element by example of the order of 250kW.
  • the on-board mass i.e. the cage itself and the rest of the assembly turning point, is around a hundred tonnes, i.e. around ten times the mass embedded in conventional spirals
  • the machine of the invention is associated with an installation for conditioning the spools of shaped wire, in which the T-wire is correctly pre-bent (in particular to avoid unwinding tendency) and sharp.
  • the spiral itself has downstream of the coils a cutting device and straightener (scraper), the cutting device being disengaged during normal operation; if necessary, the machine can operate at upside down, with wire rewinding after bending and cutting.
  • the spiraling machine of the invention is above all designed to work with two drawn form wires and two stapling wires drawn, for a typical pipe vault application "rough bore” described in document API17B “Recommended practice for flexible pipes "published on June 1, 1988.
  • the speed of the bichenilles is controlled to the tension of the wire in its forming loop between the bichenille and the point committing.
  • the spiraling machine works with two shaped wires pushed and two stapling wires pulled.
  • the speed of the tracks is subject to the rotation speed of the cage.
  • the spiraling machine works with a wire of pushed form, arranged back towards the inside of the pipe, and a pulled wire placed back to the outside, which comes hang around the neighboring turns of pushed wire.
  • This mode of work can be used to make a carcass or a vault pressure.
  • the other two coils, which do not have to receive stapling wire can be used to receive wire commonly called hoop wire, the spiral of the invention thus allowing the realization in a single pass of the pressure vault and the hoop.
  • FIGS. 12 and 13 We will first describe, with reference to FIGS. 12 and 13, a example of flexible tubular pipe that the invention allows to manufacture.
  • Figure 12 shows a smooth bore pipe (at smooth internal passage) comprising from inside to outside a sheath sealing in plastic 101, in particular in polyamide, in fluoropolymer or crosslinked polyethylene; a pressure vault 102 constituted by the helical winding of a T-shaped wire 103 and a wire stapling 104 in U, or by the interwoven winding of two wires of form 103 and two stapling wires 104, the pitch of the helices formed by each wire then being twice as large as in the previous case; the case if necessary an intermediate sheath 115; a tensile armor made up of two crossed plies of metal wires 105, 106 and an outer sheath sealing 107.
  • Figure 13 shows in detail the consecutive turns of wire shape 103 and stapling wire 104.
  • the section of wire 103 affects the shape of a T with a thick bar, facing outwards, the bar of the T being on the side internal of the winding, the T having a fairly short central leg and two even shorter lateral projections on the same side of the T bar.
  • the height A (or thickness) is of the order of 12mm, 14mm, 16mm or more.
  • Two T-shaped turns neighbors are hooked by a stapling wire 104 of section substantially in U (reversed in figure 13) with short legs.
  • the threads which interest the invention are not however limited. precisely to the T-shapes described in this document.
  • the invention is particularly interesting with all the son of large, non-self-stapling section, i.e. most often characterized by plane symmetry and an absence of axial symmetry (unlike wires self-stapling in S or Z), without these geometric considerations limit the scope of the applications of the invention, in particular because the machine can also be used for winding wires self-stapling, or non-stapling son, for example section son rectangular such as the wires used to form the reinforcing plies say frets.
  • the spiraling machine which will now be described, in particular in reference to Figures 1 to 10, has the main purpose of making from two form wires and two stapling wires the pressure vault 102 around the sheath 101 of the pipe described above, but as will be seen further on, it can be used to make other types of windings.
  • the flexible element 2 will designate the tubular element which must be carried out at least partially by winding, whatever its manufacturing stage, possibly distinguishing when necessary between hose 2 'before winding (this is for example the only inner sheath 101) and the hose after winding 2 "(this is then example of the assembly of the sheath 101 and the pressure vault 102).
