摘要:
The invention concerns an elongated, multilayered tubular body (1) comprising an elongated, tubular inner hollow core (5), an elongated, tubular inner casing (4) and an elongated, tubular outer casing, the inner casing surrounding the hollow core, the outer casing surrounding the inner casing, the outer casing comprising at least two layers (2,3), each layer consisting of one or more longitudinally preformed, flat elongated metal strips, the preforming of the strips such that the strips have been bent helically in such, a way that the consecutive windings of the helix touch or almost touch to each other, each strip in one layer overlapping with other strips in other layers, the layers in the outer casing being bound to each other by an adhesive. The invention further concerns the use of the elongated tubular bodies in the transport of hydrocarbons as oil and/or natural gas optionally containing hydrogen sulphide and/or carbon dioxide or for the transport of gasses and/or liquids as carbon dioxide, hydrogen, water or steam.

Methods for repairing a defect in a pipeline. In some embodiments, the method includes filling the defect with a filler such that an outer surface of the defect is substantially flush with an adjacent outer surface of the pipeline, curing the filler, wrapping a reinforcing material around the pipeline over the defect region for a plurality of turns, coupling the reinforcing material to the pipeline, wherein a pressure load applied to an inner surface of the pipeline is transferred through the pipeline and the filler to the reinforcing material so as to increase a safe operating pressure of the pipeline, and electrically coupling the reinforcing material and the pipeline, whereby an electrical potential in the pipeline is transmitted to the reinforcing material.

A hose (10) comprising a tubular body (12) of flexible material arranged between an inner and an outer helically wound wire (22, 24). The hose (10) further comprises an elongate member having opposing longitudinal edges, the elongate member being helically wound around the tubular body such that the opposing longitudinal edges of the layer are in an adjacent or overlapping arrangement, wherein each longitudinal edge includes a formation capable of interengaging with a cooperating formation on the opposing longitudinal edge.

This invention relates to flexible tubular conduits or pipes particularly in situations where the conduits need to withstand relatively high pressures. In such cases, the conduits are reinforced by helically wound armor which is compliant in flexure, and profiled to allow each subsequent turn to interlock with the previous turn. The invention provides a locking mechanism (8, 9) located in the axial direction of the tubular conduit comprising one or more projections (8) on one or both radial sides and a corresponding number of sockets (9) on the opposing radial sides, such that the projections (8) of one turn of the winding (10) engaging in the sockets (9) of the next turn of the winding (10), each projection (8) having an enlarged head portion (11) connected to a body by a narrow neck portion (12), and each socket having a corresponding shape to hold the projection captive in the socket, the sockets (8) and projections (9) having dimensions to allow a limited relative rotation between the adjacent turns of the winding and to resist separation, closing, and relative radial movement of the respective turns.
