  • Patent number: 8505587
    Abstract: For use in the manufacture of reinforcement layers for flexible pipes which are capable of absorbing compressive or tensile forces, and which are used for the transport of oil and gas, a thermoplastic material is applied to a strength-imparting layer. The strength-imparting layers are reeled on reels, and following unreeling, are laminated by application of heat and in direct continuation applied to the pipe. The strength-imparting layer includes a polymer reinforced with at least 20% by volume of fibers. The thermoplastic is of a reversible type (it may change from being relatively soft, but non-sticky to being sticky by changes in temperature). The method allows manufacture of very strong reinforcements for flexible pipes which cannot be manufactured using solid material, e.g., steel, since high performing bending forces are required in shaping. A reinforcement element is provided which is capable of resisting instantaneous shock loads as the thermoplastic material is protective.

  • Patent number: 8256469
    Abstract: A method for the drainage of permeate gases from a flexible tubular pipe and a pipe embodied for carrying out the method. The pipe comprises at least one inner pressure sleeve, for the transport of hydrocarbons, which contain permeate gases which diffuse across the wall of the inner pressure sleeve. The pipe has an outer sleeve and several reinforcement layers, arranged in an annular zone between the outer sleeve and the inner pressure sleeve. The annular zone has transport ducts in which the permeate gases can circulate towards the removal. The method comprises a forced circulation of the permeate gases in the annular zone through the transport ducts towards the removal.

  • Patent number: 8087430
    Abstract: A leak detecting hose for transporting fluid. The hose has an inner and outer layer. The outer layer circumscribes the inner layer. A transition layer is located between the inner and outer layer, and the transition layer provides a flow path for the fluid in the hose when the inner layer is breached. A first conductive wire is placed in contact with the transition layer, and a second conductive wire is placed in contact with the transition layer. The conductive wires are adjacent to and spaced from each other. When the inner layer of the hose is breached, the first and second wires will contact the fluid in the flow path. The conductive wires are radially equidistant from the center of the hose and helically wound around the inner layer. The transition layer may include reinforcement material, which can have filaments that provide a flow path for the fluid.

  • Patent number: 8084108
    Abstract: A core having enhanced ID stiffness is provided. The core includes inner, intermediate, and outer wall zones. The intermediate zone is spring-like in that it minimizes deformation of the inner zone from a radial deflection of the outer zone by absorbing at least some of the deformation. Similarly, the intermediate zone minimizes deformation of the outer zone from a radial deflection of the inner zone by absorbing at least some of the deformation. The intermediate zone includes at least first and second intermediate layers and one or more intermediate support layers. The first and second layers include a number of plies and gaps that are offset from each other, i.e. the plies of the first layer are radially aligned with the gaps of the second layer. The intermediate support layers are between the first and second layers and extend radially across the gaps of the first and second layers.

  • Patent number: 8082954
    Abstract: A flexible pipe for transporting a fluid in a marine environment. The pipe comprises a liner for confining the fluid, an armoring layer surrounding the liner, and an outer protective sheath surrounding the armoring layer and allowing radial expansion and contraction of the armoring layers. The outer protective sheath comprises at least two protective layers of helically wound composite wires with essentially opposite winding angles and locally held together, providing a relatively flexible yet fixed structure of the outer sheath. The outer sheath is held together in an array of discrete spots or along linear or curved paths. Flexibility is maintained because the stiffness in shear in the wires of adjacent protective layers may be made much larger in areas being locally held together than outside these areas. This allows a change of angles between the wires of two adjacent layers of the outer protective sheath during elongation or shortening of the pipe.

  • Patent number: 8006722
    Abstract: A pipeline for conducting air for air conditioning in aircrafts includes a body portion formed with foamed plastics material or with a dense plastics material. The body portion defines a longitudinal axis and includes an outer surface carrying a wrapping for reinforcing the pipeline. The wrapping includes a plurality of adjacent contacting layers formed by at least one linear reinforcing element wound into a plurality of windings, with adjacent layers having windings angled in opposite directions to form a net-like structure of the wrapping. At least one of the spacing between the windings along the longitudinal axis or the angle of slope between the windings and the longitudinal axis varies in certain sections to change the winding density as a function of local mechanical load requirements on the pipeline.

  • Patent number: 7987875
    Abstract: A flexible, typically un-bonded, armored pipe, and a method manufacturing a flexible pipe. The pipe has a center axis and comprises an inner liner surrounded by a radial armoring and an axial armoring, the radial and axial armoring each comprising at least one armoring layer of armoring profiles wound with winding angles ?i relative to the center axis. The winding angle of the innermost armoring layer ?innermost is larger than the winding angle of the outermost armoring layer ?outermost. The outer radial armoring layer has sufficient strength and flexibility to prevent prohibitively large radial deformations of underlying axial armoring layers without considerably increasing the radial contact pressure on underlying axial armoring layer. At least one fibrous layer, comprising at least two fibrous cords wound on an underlying layer, surrounds the outermost armoring layer. The flexible pipe is useful in terrestrial and/or subsea transport of fluids at elevated temperature and/or pressures.
