Definitions
- the present invention relates to a flexible pipe capable of being used for the transport of fluids such as hydrocarbons for example.
- Some flexible pipes include, from the inside to the outside, an internal sealing sheath made of plastic, elastomer or other relatively flexible suitable material; an unsealed flexible metal tube which must resist the forces developed by the pressure of the fluid flowing in the pipe; one or more layers of armor and at least one external sealing sheath made of polymeric material.
- This type of flexible pipe is often called “smooth-bore" by specialists in the field.
- ⁇ -bore from non-smooth passage
- a non-waterproof flexible metal tube called a carcass, constituted by a profile wound in turns stapled to each other.
- others such as for example a stapled strip or a stapled form wire such as a T, U, S or Zeta wire, an internal sealing sheath of polymeric material, one or more layers of armor capable of resist the forces developed by the pressure of the fluid flowing in the pipe and the external forces to which the flexible pipe is subjected, and at least one external protective sheath of the polymeric type.
- the internal sealing sheath is directly extruded, continuously, onto said carcass which has interstices or gaps between the wound turns.
- the internal diameter of the internal sealing sheath be as close as possible and even equal to the external diameter of the flexible metal carcass.
- the internal sealing sheath which is extruded on the metal carcass, becomes contracts on the latter during cooling.
- shrinkage deformations which appear on the internal face of said internal sealing sheath and in particular on either side of the joints between the turns of the metal frame.
- shrinkage is due, it seems, to the differential shrinkage of the material used for the internal sealing sheath, due to the variation of the cooling gradient in the thickness of the internal sealing sheath, cumulated at l effect of the junctions of the turns of the metal carcass.
- the extruded plastic sealing sheath being in contact by its internal face on the metal carcass which is at room temperature, it follows that the cooling of said internal face is very rapid, which causes surface irregularities or shrinkage; this phenomenon is amplified at the junctions of the turns of the metal carcass, the differential constriction in these places causing variations in local thickness of the internal sealing sheath.
- the sealing sheath is made of semi-crystalline polymer, sensitive to the presence of surface defects causing the sheath to lapse, possibly going as far as breaking, as in. for example PNDF (polyvinylidene fluoride), this very often leads, in operation, to degradation of said sealing sheath (rupture) which then no longer ensures its sealing function.
- PNDF polyvinylidene fluoride
- a first solution consisted in having, between the metal carcass and the internal sealing sheath, a thin sacrificial sublayer (about 2 3 mm), in a suitable material such as PVDF, which then serves as a thermal shield.
- the internal sealing sheath is extruded on said sacrificial sublayer but ensuring that there is no "weld” or intimate connection between the sealing sheath and the sacrificial sublayer, so that the cracks that can spread from the inside of the underlay to the outside are blocked at the interface of the sealing sheath and the sacrificial underlay.
- the object of the invention is to propose, within the framework of a flexible pipe, a system for covering the carcass which serves as a heat shield for the extruded plastic sheath so as to avoid the formation of shrinkage, but which does not have the disadvantages of the above solutions and allows simple installation.
- the invention achieves its object by means of a flexible pipe of the type comprising from the inside to the outside a carcass produced by a metallic helical winding with a short pitch, providing overlaps, a covering layer serving as a thermal screen made up of ribbons.
- a taping machine for placing around the carcass several thin plastic ribbons with long pitch, preferably between 10 ° and 35 °. These ribbons are preferably wound with overlap, which ensures that the entire carcass is covered by this layer.
- This overlapping of the tapes can create a defect on the internal surface of the extruded sheath, but this possible defect is helical with a short pitch, and therefore without much influence on the sealing sheath.
- the overlap of the ribbons is typically of the order of 10% of the ribbon width.
- the ribbon is thick enough to act as a heat shield for the sealing sheath during extraction (until the internal surface of the sheath freezes) to avoid the formation of shrinkage, and yet quite thin to allow the indentation of the sealing sheath in the carcass gaps to allow hooking.
- the indentations form approximately 20% to 75% of the volume of the gap.
- the thickness of the tape is also depending on the material of which it is made but it is generally less than 1/5 th of the thickness of the pressure sheath and preferably of the order of 1 mm or even less.
- the tape Since the tape has no function in the behavior of the flexible pipe, it may very well degrade on contact with the extruded plastic sheath, as long as it nevertheless serves as a thermal shield until the surface internal of the plastic sheath freezes. It should therefore have a lifespan of about one minute.
- the tape In order to be able to lay this tape in great length and to avoid the risks of breakage during its installation (which would make it necessary to repeat the extrusion) or of uncontrolled elongation of the tape, the tape preferably has a tensile strength greater than 20 daN (tensile force imposed by the taping machine).
- This resistance can be ensured by the basic constituent material of the ribbon or by reinforcements, in particular metallic or textile reinforcements (of fibers or "rovings" in Kevlar® or carbon type), for example in the form of longitudinal reinforcements or of mesh.
- the width of the ribbons is preferably close to the external diameter of the carcass so as to ensure covering with 3 to 5 ribbons.
- the material of the covering tapes is chosen to have a relatively low flexural strength (modulus of elasticity) so as to deform at the joints to allow the desired creep when the sheath contracts.
- the material of the ribbons can be of the heat-shrinkable type, reinforced or not, which can improve the formation of the indentations.
- the ribbon may have longitudinal notches (which do not reduce the tensile strength of the ribbon), the indentation of the pressure sheath in the carcass being effected through these notches.
- the ribbons must be made of a material compatible with the pressure sheath, that is to say polyolefins, polyamides (preferably of polyamide 11 RILSAN® type), fluoropolymers (homo- or copolymers) modified or not (polyfluoride vinylidene "PVDF” or polyfluoralkoxyl) or hydrogen carbonated, fluorinated or silico-fluorinated elastomer (thermoplastic elastomer or thermoplastic urethane).
- the tape must have a lower flexural strength than the contraction force of the pressure sheath when it cools. The flexural strength of the tape depends on the hot module, the thickness of the tape.
- the force generated by the contraction of the pressure sheath depends on the thickness of the pressure sheath and the modulus of elasticity of this sheath and on the size of the back-up.
- a person skilled in the art knows how to determine the behavior of the pressure sheath during its cooling by using, for example, the ABAQUS software and therefore the maximum thickness of the tape to allow the indentation of the pressure sheath in the carcass.
- an example of a material suitable for the tape is a polyurethane polyester (TPU) known under the name ESTANE® 58271, the viscosity of which decreases rapidly under temperature. high (the layer can be removed in 30 days at 120 ° C).
- the tape In thin thickness in contact with the extradate (at an extrusion temperature above 230 ° C for a PVDF), the tape will have a duration of a few minutes, sufficient to allow the internal surface of the pressure sheath to freeze (solidification temperature close to 160-170 ° C for a PVDF).
- FIG. 1 is a partial perspective view of a flexible pipe of the "rough-bore" type comprising the covering tapes according to the invention
- FIG. 2 is a partial longitudinal section view of part of the flexible pipe of FIG. 1 showing the covering tapes and the sheath which covers them
- a flexible pipe 1 of the "rough-bore" type comprises from the inside to the outside:
- a flexible metal tube or carcass 2 produced by helical winding with short pitch (that is to say with a winding angle close to 90 °) of strip or metal wire of predetermined section, an internal sealing or pressure sheath 3 of polymer disposed around the carcass 2,
- a pressure vault 4 resistant mainly to the pressure developed by the fluid in the sealing sheath and constituted by the helical winding with short pitch (that is to say with a winding angle close to 90 ° ) around the internal sheath, one or more stapled metal wires (self-stapling or not); shaped wires have a Z or T section or their derivatives (teta or zeta), U or I,
- one or more plies of armor 5 wound in a long pitch for example two crossed plies of tensile armor whose armouring angle measured on the longitudinal axis of the pipe is less than 60 °,
- the tape 10a or 10b is pressed after extrusion of the sheath 3 in the gap forming a helical groove filled in by the extruded sheath 3, thus forming a helical indentation 13.
- the ribbons forming the covering layer are wound in a long pitch with a winding angle of less than 35 °.
- the covering layer can be produced by one or more ribbons arranged longitudinally along the axis of the pipe (the angle
- FIG. 3 shows various examples of covering tapes usable in the invention.
- the ribbon 10a of FIG. 3 comprises longitudinal reinforcements 14, for example made of Kevlar® or carbon, arranged within a plastic matrix.
- the reinforcements integrated into the material of the ribbon 10a are in the form of a trellis 15, for example metallic.
- the tape 10a has longitudinal incisions or notches 16 which allow the material constituting the sheath to pass through when it is extruded and facilitate the formation of larger indentations.
