  • Patent number: 10189225
    Abstract: A high pressure hose having steel wires with different load elongation properties, which are introduced into the subsequent reinforcement layers of the hose. The difference in load elongation is quantified by the E-ratio of the wire that is equal to the tensile strength divided by the elongation at break. The steel wires of the radially outermost steel wire reinforcement layer have the highest E-ratio, while the radially innermost steel wire reinforcement layer has the lowest E-ratio. The E-ratio of any steel wire reinforcement layer is not lower than the E-ratio of any inner laying steel wire reinforcement layer. The E-ratio of the steel wires can be influenced by either a thermal treatment or by a mechanical treatment. In the mechanical treatment crimps or bends can be introduced into the wire by guiding them through a preforming device.

  • Patent number: 8919389
    Abstract: A tubular structure and method for making a tubular structure are provided, where the tubular structure includes at least one layer of braided strands. In general, at least one portion of the braided strands exhibits a braid pattern of crests and troughs (e.g., a wave pattern, which may include sinusoidal, square, and/or sawtooth waves) along a length of the tubular structure. The wave pattern can be created by rotating the mandrel onto which the tubular structure is braided during the braiding process, such as by angularly oscillating the mandrel about its longitudinal axis or about its transverse axis. As a result, the tubular structures may have increased radial strength, collapse resistance, torque transmission, column strength, and kink resistance. The tubular structures may be used in medical devices, such as stent-grafts, as well as in other medical and non-medical devices, such as in hoses, tubing, filters, and other devices.

  • Patent number: 8789562
    Abstract: Provided is a flexible tube which is used to load fluid from a floating facility on the sea onto a tanker, which is suitable for transport of cryogenic fluid such as LNG, and which is capable of quickly and reliably detecting leakage of the fluid in the tube. Also provided is a structure for detecting leakage of fluid in a tube. A water impermeable and heat insulating layer is provided on the outer periphery of a heat insulating layer. The water impermeable and heat insulating layer, together with the heat insulating layer, thermally insulates LNG flowing through a corrugated tube from the outside of a flexible tube. Unlike the heat insulating layer, the water impermeable and heat insulating layer is poor in liquid permeability, and fluid such as LNG hardly permeates the water impermeable and heat insulating layer. That is, the water impermeable and heat insulating layer serves as a water impermeable layer between the inside and outside of the water impermeable and heat insulating layer.

In order to ensure a reliable and enduring joint between inner pipe and joint element, it is proposed in accordance with the invention, that the radially projecting collar of the joint element is defined by a ring-shaped end face (20) and by a thereto joined ring step (22) extending radially towards the inside of the pipe and recessed axially from the ring-shaped end face, and wherein the plastic material of the inner pipe (10) engages in the ring step (22) from the inside of the pipe.

  • Patent number: 8056585
    Abstract: The invention relates to a flexible pipe for transportation of fluids and gasses, e.g. useful in water transportation, and in offshore transportation of crude oil e.g. from seabed to an installation or between installations. The flexible pipe of the invention comprises a new type of armouring layers which is made from a combination of one or more profiled wires and one or more metal strips. A folded strip is an endless unit with at least one fold and a width which in unfolded condition is at least 6 times its thickness, such as at least 10, such as at least 15, such as at least 25 times its thickness or even up to 100 or 500 times its thickness. A profile is a preshaped non-folded cross sectional profile. The profile may preferably have a width of less than 6 times its thickness. The term ‘endless’ is used to indicate that the tapes and profiles are very long compared to their other dimensions.

  • Patent number: 8048351
    Abstract: A hose for use in bio-pharmaceutical applications includes an innermost tubular layer made from a fluoropolymer material. The tubular layer has an inner, relatively smooth and pure surface that defines an opening for transfer of various media. A layer of silicone is disposed next to an outer surface of the innermost tubular layer through use of, for example, an extrusion method. The outer surface of the tubular layer may first be modified by various treatments or chemicals to facilitate the adhesion of the silicone layer thereto. The silicone material may be solid or foamed. A reinforcement layer may be disposed adjacent to an outer surface of the silicone layer. The reinforcement layer may be formed of a wire braid having gaps. An outer jacket of silicone may be attached to the reinforcement layer and to the inner silicone layer through the gaps in the reinforcement layer.

  • Patent number: 7954518
    Abstract: The disclosure pertains to installing a plurality of tear cords between a metal tube and a protective jacket. The multiple cords facilitate ease of removal of the protective jacket by creating a panel of the jacket that is detached from the remainder by pulling on the multiple tear cords. The resulting widened space can be used to remove the tube from the remaining protective jacket. The jacketed tubes may be used in a hydrocarbon production downhole well bore. The tubes may be used to furnish hydraulic fluid or chemicals into the well bore. The contents may be pressurized or under vacuum. The jacketed tubes are hermetically sealed. The tubes, which may be 1 inch in diameter, are joined using compression fittings. Tear cords are used to facilitate removal of the protective jacket without damage to the tube surface thereby facilitating the placement of compression fittings and maintaining the integrity of the tube wall.

    Abstract: A flexible pipe for fluid transport especially in offshore application has a first extruded tube having nylon and a first layer having aromatic polyamide disposed about the first tube. A plurality of rings composed of stainless steel are disposed about the first layer. Each of the rings has first ends with circumferential lips and second ends with circumferential grooves interconnecting together. These lips and grooves permit adjacent ones of the rings to tilt relative to one another by about 1.5-degrees for every 4-inches of flexible pipe. A second extruded tube having fiberglass is disposed about the plurality of rings, and an exterior jacket having nylon is disposed about the second tube.

  • Patent number: 7913719
    Abstract: The multi-layer tape wrapped tubing for effectively impeding the diffusion of vapor is made in a continuous in-line process and has three distinct layers: an inner tubing layer, a middle diffusion barrier layer and an outer jacketing layer. The inner tubing layer comes into contact with liquid and vapor. Vapor that might ordinarily diffuse through the tubing is impeded by the diffusion barrier layer. The diffusion barrier layer is a laminate comprising a diffusion barrier film with a very low vapor diffusion rate sandwiched between layers of thermoplastic. The diffusion barrier layer is wrapped around the inner tubing one or more times. The outer jacket layer is a polymeric jacket which is extruded onto the diffusion barrier layer wrapped inner tubing.
