Abstract:
In accordance with embodiments of the present disclosure, a slickline for use in well drilling and hydrocarbon recovery operations includes a cable and an intermediate layer disposed around the cable. The slickline also includes a doped polymeric coating layered around the intermediate layer. The doped polymeric coating is a different material from the intermediate layer, and the doped polymeric coating includes a polymeric material doped with an element that is detectable within the doped polymeric coating via a detection machine for purposes of determining wear or other aspects about the conditions of the slickline.
Abstract:
A self-wrapping, textile sleeve for routing and protecting elongate members from exposure to abrasion, thermal and other environmental conditions and method on construction thereof. The sleeve has an elongate wall constructed from interlaced yarns having interstices between adjacent yarns. At least one of the yarns is heat formed at one temperature to form the wall as a self-wrapping wall curling about a longitudinal axis of the sleeve. The wall has an inner surface providing a generally tubular cavity in which the elongate members are received. The wall also has an outer surface with a cured layer thereon. The cured layer is cured at the one temperature at which the yarns are heat formed into their self-wrapping configuration, wherein the cured layer fills the interstices between adjunct yarns to form an impervious layer on the wall.
Abstract:
A method for manufacturing a flexible composite belt or cable, in the method, one or more parallel reinforced plastic profiles (11) are manufactured by pultrusion, continuous lamination or other continuous method. After surface treatment, the reinforced plastic profiles (11) are guided at a short distance from one another to coating treatment, which is carried out by extrusion or lamination or pultrusion. in the coating treatment, the reinforced plastic profiles are enveloped with a coating material (12) improving wear resistance which joins the reinforced plastic profiles (11) together and forms the coating of a finished belt or cable (10). Finally, the finished belt or cable (10) is wound on a reel.
Abstract:
A high traction synthetic rope comprising a braided sheath (8) adhered to a synthetic strength member (7) by means of a first synthetic portion (9) and portions of material (23) adhered to the outside surface of the braided sheath by means of a second synthetic portion (21), where the portions of material (23) are formed of a substance that differs from a substance mainly forming the second synthetic portion (21) and exhibits greater friction when wet or with greasy conditions and measured on an iron surface than does the substance mainly forming the second synthetic portion. Also methods of manufacturing such a high traction synthetic rope are disclosed. The rope shows reliable traction on driven rotating elements during wet/greasy conditions.

Abstract:
A rope having a cut-resistant jacket which includes a core comprised of a plurality of sub-ropes. The sub-ropes may be in a parallel strand configuration. The sub-ropes and the strands thereof may be made of fibers of a synthetic material, such as polyester, nylon, polypropylene, polyethylene, aramids, or acrylics. A cut-resistant jacket surrounds the core and is made from a material that has increased strength and/or abrasion resistance over the material of the core. The cut-resistant jacket may comprise steel wires and may further comprise braided steel wires or rope. The braided steel wires or rope may be covered with a plastic material for increased corrosion resistance. A filter layer may be disposed between the core and the cut-resistant jacket and may be wrapped around an outer surface of the core prior to the cut-resistant jacket being formed.
Abstract:
According to some embodiments, a cable protection system to at least partially shield a cable from heat, fire, an impact or other potentially harmful event or occurrence comprises a first encompassing member configured for placement around the cable or cable bundle, wherein a first void is defined between the first encompassing member and an outside of the cable or cable bundle. The system additionally includes a second encompassing member positioned around the first encompassing member, wherein a second void is defined between the first encompassing member and the second encompassing member. Further, the system comprises one or more fill materials positioned within the second void. In some embodiments, the fill material comprises vermiculite, ceramic and/or one or more other materials. The first void permits the cable protection system to be slidably moved relative to the cable or cable bundle.
Abstract:
A method and apparatus to produce a non-helically wound subsea umbilical is disclosed. The apparatus to produce a non-helically wound umbilical may be portable to facilitate manufacturing of subsea umbilicals in remote locations. This apparatus is smaller and more economical to build and operate than conventional cabling machines that currently are used by many manufactures to produce helically wound subsea umbilicals.
Abstract:
The invention relates to a coated metal surface including successively, starting at the metal, at least one layer of polyurethane and at least one layer of thermoplastic polymer, it being possible for a binder to be placed between the polyurethane and the thermoplastic polymer.It is useful for covering pipes, electrical cables, telecommunication cables and stay wires.
Abstract:
A hoist rope for an elevator is formed from synthetic, non-metallic materials. The hoist rope includes a plurality of load-carrying strands with each strand encased within a coating layer. The coating layers provide protection against wear and provide sufficient lubricity to permit relative movement of the strands to equalize loading on the strands. The plurality of strands are surrounded by a jacket. The jacket provides sufficient traction with a traction sheave, transfers traction loads to the strands while permitting movement of the strands, and provides a flame retardant characteristic to the hoist rope. In one embodiment of an passenger conveyor system, the hoist rope is engaged with a traction sheave having a sheave liner the material for the jacket and sheave liner are selected to optimize the coefficient of friction between the hoist rope and traction sheave.
