    摘要: Aspects of the present disclosure relate to methods of coating a coiled tubing string, methods of conducting tubing operations using a coated tubing string, and associated apparatus thereof. In one implementation, a method of conducting a coiled tubing operation, includes forming a tubing string. The tubing string has a central annulus, an inner surface, and an outer surface, and the tubing string is formed from a metallic material. The method also includes coiling the tubing string onto a spool, and moving a coating into the central annulus. The method also includes curing the coating onto the inner surface of the tubing string to form a layer of the coating on the inner surface of the tubing string.

    摘要: A component of an exhaust system for an internal combustion engine. The component comprises an exhaust system structure having an interior through which exhaust gases flow and an exterior, and a thermal insulating wrap for thermally insulating at least a portion of the exterior of the exhaust system structure. The thermal insulating wrap comprises an aqueous mixture comprising an inorganic binder and inorganic filler particles, and a fabric comprising inorganic fibers. The fabric is impregnated with the aqueous mixture so as to form a pliable binder wrap. The pliable binder wrap is wound completely around at least a portion of the exhaust system structure. It can be desirable for the component to further comprise at least one thermal insulator comprising inorganic fibers, where the thermal insulator is disposed between the pliable binder wrap and the exterior of the exhaust system structure.
