  • Patent number: 11226057
    Abstract: Techniques for implementing a pipe segment that includes a tubing inner barrier layer that defines a pipe bore through the pipe segment, a venting tubing annulus implemented around the tubing inner barrier layer, in which the venting tubing annulus includes a first solid material implemented to define a venting fluid conduit, a tubing intermediate barrier layer implemented around the venting tubing annulus, a reinforcement tubing annulus implemented around the tubing intermediate barrier layer, and a tubing outer barrier layer implemented around the reinforcement tubing annulus. The reinforcement tubing annulus includes a second solid material that is different from the first solid material and is implemented to define a reinforcement fluid conduit. Additionally, the venting fluid conduit facilitates venting fluid that permeates from the pipe bore through the tubing inner barrier layer out from the pipe segment before the fluid contacts the second solid material in the reinforcement tubing annulus.

  • Patent number: 11058844
    Abstract: The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.

  • Patent number: 8997795
    Abstract: A flexible hose (1) has at least two textile reinforcement inlays or inserts (5, 6, 7) and an inner layer (2) made of elastomeric material. The flexible hose can assume various curvature geometries and, on the other hand, is still pressure-resistant because a textile reinforcement inlay (5) made of a peripherally closed, tubular knitted or woven fabric is applied to the elastomeric inner layer (2). A textile layer (6), which is rubber-coated on both sides, is wound as a further textile reinforcement inlay onto the tubular knitted or woven fabric (5).

  • Patent number: 8910667
    Abstract: An expandable hose is provided formed of a sidewall formed of a spirally wound flexible member which defines an axial passageway surrounding a center axis of the formed hose. Both side edges of the flexible member in the spirally wound position are engaged with a cap member which provides a skeletal structure to maintain the axial passageway open and to bias the hose back to a collapsed length from the extended length. A fold formed in the spirally wound flexible member allows for increased distance between the two side edges and an increased maximum extended length. A telescopic pole engaged with the formed hose provides an improved extendable vacuuming tool.

  • Publication number: 20140318662
    Abstract: An elongate tape and method of producing an elongate tape are disclosed. The tape is suitable for forming a helically wound layer of interlocked windings in a flexible pipe body, and is configured for interlocking with adjacent windings, wherein the tape has a cross-sectional profile including: a first surface that in use forms a radially inner surface of the helically wound layer; a further surface, in use forming a side wall extending radially outwards, away from the first surface, and for forming a contact surface with a region of an adjacent winding; and a transition surface joining the first surface and further surface, wherein the transition surface comprises a curved surface, and wherein the curved surface has a larger radius of curvature in a region proximate the first surface than in a region proximate the further surface.

  • Publication number: 20140305532
    Abstract: The invention concerns an unbonded flexible pipe for subsea transportation of fluids, the pipe comprises from inside and outwards a carcass, an inner sealing sheath, a pressure armor, and a tensile armor. The pressure armor comprises at least one helically wound elongate and interlocked element in the form of a strip with a cross-sectional profile comprising a planar mid section and a first and a second interlocking edge configured to have an angle to the planar mid section and to protrude in a direction away from the inner sealing sheath to provide a channel between the first and the second interlocking edges, the pressure armor further comprises at least one helically wound elongate and non-interlocked elongate element where windings of the non-interlocked elongate element are placed at least partly in the channel such that displacement with respect to the helically wound elongate and interlocked element is limited by the first and the second interlocking edges.
