Abstract:
A reinforced hose (402) comprising an extruded core tube (404) having a circular cylindrical cross- section, a plurality of elongated reinforcement members (414), and a jacket layer (408). The plurality of elongated reinforcement members (414) are disposed within a wall of the core tube (404) and extend longitudinally between a first distal end of the core tube (404) and a second distal end of the core tube (404). The elongated reinforcement members (414) can extend in a substantially straight fashion or can extend in a helical fashion to thereby form a helix within the wall of the core tube (404). One or more of the plurality of elongated reinforcement members (414) has a greater rigidity than the wall of the core tube (404). A jacket layer (408) encapsulates the extruded core tube (404) and the plurality of elongated reinforcement members (414), and has a circular cylindrical cross-section that is larger than the circular cylindrical cross-section of the extruded core tube (404).
Abstract:
A slurry operation device with a monitoring system for detecting interior wear is disclosed. The slurry operation device is used to transfer or process solid material in a fluid, and has an enclosing cross-section. According to the invention the slurry operation device includes an interior wear layer (1) having an inner surface, adapted for contact with solid material in a fluid, and an outer surface; a support structure (3, 4, 5) wound, woven or braided about the outer surface; and an exterior cover layer (6) being disposed over the support structure. The monitoring system includes at least one moisture sensor (9) arranged to detect moisture in or at the support structure; and communication means (20) coupled to the moisture sensor for providing a signal representative of moisture detection in or at the support structure. A slurry operation plant including at least one slurry operation device according to above is also disclosed, as well as a method for installing the monitoring system for detecting interior wear of a slurry operation device.
Abstract:
Der Medienschlauch (2) dient zur Verwendung bei hohen Temperaturen und hohen Drücken insbesondere bei Verbrennungsmotoren, speziell zur Messung und Überwachung eines Fluids innerhalb des Verbrennungsmotors. Hierzu umfasst der Medienschlauch (2) einen Innenhohlraum (6), welcher von einer Flachdrahtwendel (4) umgeben ist, welche wiederum von einem Geflecht (8) umgeben ist, welches von einem Außenmantel (10) umhüllt ist. Der Aufbau bestehend aus Flachdrahtwendel (4), Geflecht (8) und Außenmantel (10) ist biegeflexibel und knickfest, temperaturbeständig bis über 150° sowie medienbeständig gegenüber Öl-, Schmier- und Treibstoffen. Zudem ist der Aufbau für einen Berstdruck größer 10 bar ausgelegt.
Abstract:
A unbonded flexible pipe with a length and a longitudinal axis is described. The pipe comprises an innermost sealing sheath defining a bore, at least one armor layer surrounding the inner sealing sheath and at least one optical fiber containing layer, wherein the optical fiber containing layer comprises at least one tape and at least one optical fiber arranged with a length of at least about 3 times the length of the flexible pipe.In an embodiment the optical fiber is incorporated into the at least one tape of said optical fiber containing layer to provide an integrated fiber tape where advantageously the optical fiber is arranged with S-shaped folds.
Abstract:
A hose (10) comprising a tubular body (12) of flexible material arranged between elongate inner and outer gripping members (22, 24), wherein the tubular body (12) comprises a sealing layer (18) arranged between inner and outer reinforcing layers (14, 16), and wherein the outer gripping member (24) is made of a flexible non-rigid material capable of being wound around the tubular body.
Abstract:
A flexible hose (10) construction with kink, crush, and burst resistance. The hose (10) is constructed of a tubular member (12) and a reinforcement strip (14) at least partially embedded in the tubular member (12). The reinforcement strip (14) is wound in a helical pattern encircling a central lumen (16) of the tubular body (12). The material forming the reinforcement strip (14) has a greater initial modulus than the material forming the tubular member (12).
Abstract:
An umbilical is shown that comprises a number of fluid pipes (4, 5, 6), electric wires (7) and/or optical conductors (8), filler material (2, 3) located at least partially around and between the fluid pipes (4, 5, 6) and the wires/conductors (7, 8), and they are collectively gathered in a twisted bundle by means of a laying operation. The umbilical further includes a protective jacket (1) that encompasses the fluid pipes (4, 5, 6), the wires/conductors (7, 8) and the filler material, and at least one load carrying element located in the cross section of the umbilical, optionally that one or more fluid pipes constitute load carrying elements. The fluid pipes (4, 5, 6), the wires/conductors (J, 8), the filler material (2, 3) and the at least one load carrying element, are alternately laid, i.e. by continuously alternating direction, in the entire or part of the longitudinal extension of the umbilical.

Abstract:
A flexible pipe formed by multiple layers of different materials, and one or more vent passages are provided in one of the layers for venting any gases permeating through the pipe.
Abstract:
An armoured flexible pipe consists of an inner liner (3), on the inside of which a carcass (1) is provided, while the outer side of the inner liner is surrounded by a layer of pressure armour and a layer of tensile armour, which in turn are surrounded by one or more layers of thermally insulating bands which are shielded from the surroundings by an outer sheath. With the object of ensuring a sufficiently low transport of heat through the walls of the pipe, on the outside of the pressure and tensile armour layers (5, 6, 7, 8) thermally insulating bands are provided, which bands are made of a polymer or a polymeric composition, such as a polymer containing at least 50 % polypropylene. The armoured flexible pipe according to the invention is especially advantageous for use in the extraction, transport or refining of mineral oil or related fluids.
