摘要:
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.
摘要:
An end fitting (200) for terminating an end of a hose comprising a tubular body of flexible material arranged between inner and outer helical wires, characterized in that the end fitting comprises: an inner member (202) adapted to be disposed at least partially within the hose; and a hose engaging member (208) adapted to press against the inner member 202 to retain the hose between itself and the inner member (202). The end fitting also includes a separate means for retaining one or more layers of the hose, the retaining means comprising an outer retaining member (232) adapted to press against an inner retaining member (230) to retain the or each layer of the hose between the outer and inner retaining members (232, 230) of the retaining means.

摘要:
This invention relates to a process for the manufacture of an elongated tube, the process comprising the following steps: (a) forming a rotating temporary tube (1), the tube having a first end at which the tube is continuously produced and a second end opposite to the first end, by continuously supplying a flat, elongated metal strip to a guiding body, which guiding body is forming a helix from the strip in such a way that consecutive windings of the helix do not overlap, and helically welding the consecutive windings of the helix formed by the guiding body to each other, (b) cutting cylinders from the second end of the rotating temporary tube (1); and (c) welding the cylinders obtained in step (b) to each other to form the elongated tube. The invention further relates to the use of the elongated tube in a process for the manufacture of an elongated, multilayered tubular body.

摘要:
The invention concerns a method for the construction of a long pipeline using a mobile pipeline producing unit, the mobile unit being able to produce specific lengths of the pipeline, each specific length being a fraction of the length of the long pipeline, the method comprising placing the mobile unit at a first position at the stretch of the projected long pipeline, producing a specific length of pipeline in one direction of the projected long pipeline, producing a second specific length of pipeline in the opposite direction, moving the mobile production unit to a second position at the stretch of the projected long pipeline, producing a third specific length of pipeline in a direction of the long pipeline, producing a fourth specific length of pipeline in the opposite direction, optionally moving the mobile production unit to a further position at the stretch of the projected long pipeline, producing a further specific length of pipeline in a direction of the projected long pipeline, producing another further specific length of pipeline in the opposite direction and optionally repeating this process one or more further times, and connecting all produced specific lengths. The invention further relates to pipelines made according to the method described above and to the use of the pipelines in the transport of gas and/or liquids, especially crude oil and natural gas.
