Abstract:
An elevator tension member is presented that has one or more steel cords as strength members that are encased in a jacket of thermoplastic polyurethane elastomer. The thermoplastic polyurethane elastomer is selected on the basis of its thermal properties in that the glass transition temperature of the hard phase (Tg HS) is above 90°C. In preferential embodiments that thermoplastic polyurethane elastomer has a crystallisation temperature (Tg) that is at least 20°C higher than Tg HS. In other preferential embodiments the sum of Tg HS and Tc is higher than 200°C. Such thermoplastic polyurethane elastomers exhibit an unexpected increase in useful lifetime when compared to conventionally used polyurethanes. Moreover the invention provides a simple method to select an appropriate thermoplastic polyurethane elastomer.
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 jacket (2) for a load-bearing, lengthy body (3), wherein the jacket (2) is comprised of a plurality of braid elements (12) which, when braided, enclose at least a portion of the lengthy body (3), and wherein the braid element (12) is comprised of a braided ribbon. A method of forming the jacket (2) is also described.
