Definitions

  • the present invention relates to a flat tape intended to reinforce a pipe for transporting a pressurized fluid, especially a flexible pipe for transporting hydrocarbons and gases.
  • this technique is adopted because it allows the overall gap to be distributed over a large number of tapes around the perimeter of the tube; this is because, owing to the manufacturing tolerances of the pipe on the one hand and the deformations of the pipe when in service (expansion owing to the effect of the internal pressure) on the other hand, gaps necessarily appear, the sum of which gaps gives an overall gap which must be distributed between the tapes; if there is a relatively large number of tapes, for example fifty or so, it is easier to control this overall gap since it is distributed over all the tapes, which gives an acceptable mean relative gap per tape, but which would not be acceptable with a much smaller number of tapes.
  • the way the tapes are positioned amongst themselves during the taping operations is less precise than when an armoring machine is used. There is therefore poor control of the gaps and the positioning of the tapes.
  • the external diameter of the internal tube varies because of the manufacturing tolerances, it is impossible to compensate for this variation when an already dimensioned wide tape is used, whereas with a narrower tape it is sufficient to modify the number of tapes loaded into the armoring machine.
  • the textile tape used to produce the reinforcements is a tape having edges that are thinned over a certain width so as to allow an overlap of the thinned edges that does not result in an appreciable overthickness.
  • the tape is formed from a central section of approximately rectangular cross section and from two longitudinal edges that are thinner than the central section.
  • the thickness of the edges is uniform and approximately equal to one half of the thickness of the central section; their width is advantageously between 5% and 15%, preferably in the region of 10%, of the width of the central section.
  • the thinning of the overlapping edges is known per se, in fields very remote from the invention, for example in assemblies of clinkered boards or from document JP 59035924 which discloses a multilayer resin tape for forming a transparent tube that will then be sectioned to form containers.
  • the tape is produced with thinning of the lateral edges and it is wound without any clearance on itself with welding of the edges. This is the constituent tape of the tube itself, but in no way a reinforcing tape of a pipe.
  • the tape is made of a uniform resin and is not a textile tape, the method of manufacture of which is completely different.
  • the subject of the invention is also the pipe whose reinforcement is obtained by winding flat textile tapes according to the invention, and, by virtue of which, it is possible to provide wider tapes and therefore have overall fewer tapes, advantageously less than 10 per reinforcing layer.
  • FIG. 1 is a perspective view of a pipe that includes reinforcing layers produced by winding a tape according to the invention
  • FIG. 2 is a perspective view of a first embodiment of a flat tape according to the invention.
  • FIGS. 3 and 4 are sectional views of a second and third embodiment of a flat tape according to the invention.
  • FIG. 5 is a sectional view of a winding of the tape of the second embodiment, showing the overlapping of the edges;
  • FIG. 6 is a sectional view of a fourth embodiment of the invention.
  • FIG. 1 shows a pipe 1 for transporting pressurized fluids, consisting of an internal tube 2 , for example an extruded tube, covered with a first ply 3 and with a second ply 4 of reinforcing tapes, and with an external sealing sheath 5 , which is also extruded.
  • the reinforcement plies 3 and 4 are produced by cross-winding of a flat tape 10 according to the invention, with a lay angle of approximately 55° (between 52° and 58°) with respect to the longitudinal axis of the pipe. As may be seen in the figure, the adjacent edges of the tapes 10 overlap.
  • the total number n of tapes 10 around the periphery is relatively small; this is preferably chosen to be less than ten, which, for a given diameter and a given lay angle, makes it possible to determine a preferred minimum average width of the tapes equal to ⁇ Dcos ⁇ /10 (the exposed mean width of the tape, defined as the width of the central section increased by the width of a single edge in order to take account of the overlaps, is taken to be equal to ⁇ Dcos ⁇ /n, where D is the outside diameter of the tube 2 , n is the number of tapes and ⁇ is the lay angle of the tape ply).
  • FIGS. 2 to 4 show three tape embodiments that differ by the arrangement of the thin edges.
  • the width of the edges relative to that of the central section of the tape has been exaggerated in the drawings.
  • the flanges 12 may be placed at mid-height of the edges of the central section 11 (FIG. 2), either so as to alternate at the top and bottom of the two edges of the central section 11 (FIGS. 3 and 5) or exclusively at the bottom (or at the top) of the two edges of the central section 11 , or in any other arrangement.
  • FIGS. 3 and 5 the arrangement shown in FIGS. 3 and 5 is that which lends itself most naturally to the overlapping of the edges 12 , the other arrangements are suitable in practice, owing to the flexibility of the tape and to its deformation during winding.
  • the tape of the invention is a textile tape formed from layers of filament rovings 14 held in place by binding means 15 . It is formed, for example, in accordance with the teaching of document EP 0 853 547, from layers of filament rovings 14 joined together and held in place by binding means 15 and a bonding material so as to maintain a high overall weave density, for example at least 39%.
  • the bonding material for example a thermoplastic, coating the filament rovings has not been shown.
  • the tape may also be formed only by the weaving of filament rovings with a weft yarn, but with no bonding material.
  • the weave density is advantageously kept high, for example at least 39%.
  • the filament rovings 14 used as warp yarn may be of any type, such as those made of aramid (Kevlar®, Twaron® or Technora®) or made of carbon, for example.
  • the edges 12 are made of the same material as the central section, simply with a smaller thickness, and therefore for example with a fewer number of layers of filament rovings.
  • the binding means (weft yarns) to be spaced out so as, when the pipe bends, to allow the wound tapes to untwist and their longitudinal fibers to be reorganized.
  • the tape 10 of the invention makes it possible to accommodate the overall clearance during taping, by at least partially overlapping the edges 12 of the adjacent tapes.
  • This at least partial overlapping of the edges 12 prevents the formation of through-gaps (over the entire thickness of the reinforcing layer) between two tapes.
  • a gap 13 smaller than the width l of the edge is formed, which gap is not a through-gap.
  • the outer gap 13 may result in a slight set-back of the outer sheath, but this is, however, blocked by the lower edge 12 partially overlapped by the upper edge 12 of the adjacent tape.
  • the mechanical properties of the edges 12 are identical to those of the central section 11 , the presence of a gap results in a slight degradation in the mechanical properties of the armor ply at this point, which may in principle lead to a lower burst pressure than that which would be obtained with an arrangement of conventional narrow tapes with no gap.
  • This drawback may be alleviated by providing different mechanical properties, these being higher at the edges, for example by modifying the nature or the degree of twisting of the filament rovings used, or by a different weave density.
  • the embodiment of the tape 10 of FIG. 6 differs from that of FIG. 2 in that, instead of being produced by several thicknesses of filament rovings, it is produced only by weaving in two dimensions (warp yarns and weft yarns), with a single thickness of filament rovings 14 , 14 ′.
  • the rovings 14 of the central part 11 are of larger size than the rovings 14 ′ of the thin edge parts 12 .
  • a tracer on the tape 10 for example a colored yarn 16 , which allows the position of the tape during winding to be displayed.
  • This yarn 16 is advantageously placed between the edge 12 and the central part 11 of the tape 10 (this yarn has been illustrated only in FIG. 6, but it may apply to all the embodiments) in order to define the interface.
  • this yarn has been illustrated only in FIG. 6, but it may apply to all the embodiments.
