  • a tubular conduit for use in conveying fluids with small molecular size or cross-section.
  • hot fluids and more especially hot methanol
  • umbilical cables comprising a plurality of sub-units.
  • These umbilical cables may comprise a mix of wire bundles, fibre optical bundles and conduits or pipes. Connections between platforms, pontoons or craft and remotely operated vehicles (ROVs) may also require the use of umbilical cables.
  • ROVs remotely operated vehicles
  • conduits for use in umbilical cables connecting an oil platform, pontoon or craft to an oil head have been provided with a plurality of layers.
  • the innermost layer, or carcass is generally in the form of an interlocking metal coil or interlocking formed helix, which provides flexibility whilst being able to resist collapse from external pressure.
  • a plastics extruded sheath surrounds the innermost layer to inhibit leakage of the fluid through the innermost layer.
  • the braided layers are generally constructed from aramid, more especially poly-para-phenylene terephthalamide (Kevlar ® ) , or metal.
  • an outer cover of synthetic plastics material surrounds the braided layer to provide an outer seal . Such constructions are relatively costly to produce .
  • the metal innermost layer being a coil or helix, creates a corrugated surface that causes vortices in fluid flowing through it . These vortices may produce flow induced pulsations and vibrations which can affect the flow-line integrity and produce misleading readings in up-stream flowmeters. Furthermore, where liquid passes around any bends in the conduit, significant wear of the inner surface of the innermost layer can occur due to the scouring effect created by the vortices. This can result in removal of the metal of the innermost layer.
  • a further disadvantage of the previously proposed construction is that the overlapping regions of the interlocking coil or helix of the innermost layer do not provide a barrier for the fluid, which passes through the conduit. Furthermore, the plastics extruded sheaths used in this previously proposed construction have interstices between the molecules that may be greater than the molecular size of methanol which therefore allow -the methanol to pass through the plastics material and ingress into any voids in the subsequent braided layers.
  • the methanol becomes trapped in the layers and must be vented away to prevent delamination of the total structure.
  • the venting of the methanol has been achieved by pin pricking the outer sheath.
  • the structural strength against collapse provided by the layers other than the innermost layer may be lost due to seawater permeating the layers.
  • GB 2385399A describes a fluid conduit and a multi- conduit umbilical comprising a flexible fluid hose encapsulated by at least one metallised layer to minimise permeation of fluid being transported in the fluid hose.
  • the level of encapsulation differs along the length of the hose.
  • Such a hose requires expensive metallisation processes and if the level of metallisation is insufficient or damaged, the hose cannot be used for the intended purpose .
  • PCT/NO99/00215 describes a flexible composite pipe and a method for manufacturing the same, wherein the pipe has an inner liner of thermoplastic material bonded to an intermediate reinforced polymer multi-layer component, which is bonded to an outer liner.
  • Such a pipe is not suitable for deep-sea applications as polymer reinforcements are unable to resist the high external pressure encountered at the depths required for deep-sea operation.
  • PCT/FR2006/000992 discloses a flexible conduit with an anti-wear jacket for transporting hydrocarbons, comprising at least two metal sheathing covers separated by a plastics anti-wear layer.
  • Such a conduit is expensive to construct and is relatively heavy due to the two metal layers.
  • the present invention seeks to provide a remedy to one or more of the foregoing disadvantages.
  • the present invention is directed to a tubular conduit for use in conveying fluids with small molecular size or cross-section, comprising a tubular deep-sea collapse-resistant steel reinforcement, a tubular lining of PEEK within that reinforcement, and an outer tubular sheath of plastics material surrounding the steel reinforcement to protect the steel reinforcement from exposure .
  • the outer tubular sheath is especially advantageous if the strengthening material is a steel which would rust if exposed to salt water.
  • PEEK is an acronym for polyetheretherketone or polyaryletheretherketone .
  • the conduit is flexible.
  • the tubular deep-sea collapse-resistant reinforcement which may be flexible, resists the external pressure experienced in deep-sea applications, for example, depths of four kilometres, and external pressures of 40 MPa (5800 PSI) .
  • PEEK may provide a smooth inner surface, which reduces the possibility of vortices being created within fluid flowing through the conduit.
  • the PEEK liner also inhibits the escape of fluids with small molecular size or cross-section flowing through the conduit, which may cause delamination.
  • successive portions of reinforcement overlap one another, progressing along the conduit.
  • the steel reinforcement comprises a coil, each successive turn of which overlaps the preceding one as viewed from one side of the coil .
  • Such a construction provides flexibility whilst maintaining the collapse-resistant strength of the steel reinforcement .
  • the steel reinforcement comprises tubular sections.
  • the conduit further comprises a seal embedded in the reinforcement .
  • the seal may be a coil seal, and may be an elastomeric thermoplastic, advantageously, polyurethane , which bonds to the reinforcement.
  • the pressure resistance is enhanced by providing a coil seal between successive turns of the coil where they overlap.
  • seawater cannot penetrate the conduit and penetrate beyond the reinforcement. If the seawater were to penetrate beyond the reinforcement it would render the reinforcement ineffective against collapse, as the high-pressure seawater would bear down upon the inner sheath.
  • a helical seal positioned between successive turns of the coil, the seal cannot be broken by cutting or abrasion and thus maintains a seal that inhibits the pressure reaching inwardly of the collapse-resistant reinforcement.
  • the plastics material of the outer sheath is at least partially embedded in the reinforcement.
  • the plasties material of the outer sheath extends into regions between overlapping portions of the steel reinforcement.
  • Such a construction protects the steel reinforcement from exposure to seawater when in use. The likelihood that a fracture due to mechanical damage extends through the plastics material in the regions between overlapping portions of the coil is substantially reduced in such a construction. Therefore, the likelihood of ingress of seawater into the conduit beyond the steel reinforcement is substantially reduced.
  • the steel coil comprises a helical strip, the cross-section of which is elongate comprising two substantially parallel portions which are offset relative to one another and a bridging portion connecting the parallel portions.
  • the cross-section may be considered to be generally x z' shaped.
  • Such a cross- section allows the strip to overlap itself as it is coiled onto the conduit, thus providing flexibility whilst also maintaining the collapse resistance.
  • the x z' shape provides the reinforcement with an increased sectional modulus, or i-value, over a flat elongate strip, wherein the sectional modulus is calculated from
  • the substantially parallel portions may be of unequal lengths.
  • the internal angles of the ⁇ z' are in the range from about 90° to about 160°, preferably, 135°.
  • the angle of the bridging portion may vary along the length of the coil to provide unequal convolutions.
  • Such a construction varies the amount of plastics material, or coil seal, partially embedded between overlapping portions of the coil .
  • the substantially parallel portions of the steel coil viewing the latter in cross-section, have further portions on their ends which are further from the bridging portion.

  • each parallel portion and its associated further portion is preferably 135°, but maybe be anything in the range from about 90° to about 160°.
  • the strip that is wound to form the steel coil is in the range from about 8mm to about 10mm wide and in the range from about 0.38mm to about 0.5 mm thick.

  • the steel of the reinforcement comprises carbon steel, preferably, galvanised carbon steel.
  • carbon steel armour may be used in preference to more expensive stainless steel.
  • the use of stainless steel may be considered mandatory since the effect of corrosion on the reinforcement may be catastrophic .

  • tubular lining of PEEK which is substantially impermeable to small molecules may be as thin as 0.7mm in thickness providing little more than a membrane for a bore of about 13mm, it may be up to 2 to 3mm in thickness, or even thicker, to provide additional resistance to collapse under external pressure. More generally the thickness may be up to about 20% of the bore diameter, or more. For a bore of 25mm, this equates to a thickness of about 5mm.
