    摘要： An insulating section and a method for insulating a length of pipe in northern regions subsequent to installation of the pipe is provided by a prefabricated pipe insulation system comprising (a) forming a cylindrical metallic outer jacket longitudinally flanged for seaming, (b) applying a layer of synthetic insulating foam to the interior of the outer jacket thereby forming insulating sections of insulating material adhering to an outer jacket, (c) placing said sections end-to-end longitudinally and circumferentially along the length of pipe, (d) providing batten straps, adaptable to mating with the longitudinal seam, around the pipe circumference and extending between adjacent seams of insulating sections, and (e) securing the insulating section against the pipe and the circumferential battens by forming the longitudinal seam which incorporates the battens. The pipe insulating system provides a means of forming pipe insulation sections in a mobile unit near the pipe location and is particularly applicable in northern regions to insulate newly laid or existing pipelines.

    摘要： A process for making thin metal tubing as a sheath for electrical cable or as a conduit, wherein very thin metal foil is continuously converted into tubular sheathing as over an electrical cable core, the longitudinal edges of the foil being overlapped and welded, with the immediate application thereafter of a thermoplastic copolymer coating which is tightly adherent to the metal surface of the sheathing, the composite metal foilplastic tubing having substantially increased mechanical strength.
