Abstract: A device for the production of a transformer is disclosed, comprised of at least two electrically conductive windings (A, B, C) adjacent to one another, and a ferromagnetic core (11; N2; N3) linked to the two electrically conductive windings, formed by wound strip-shaped ferromagnetic material. The device comprises guide members (9) configured and arranged so as to define a closed path linked to the two electrically conductive windings, along which one or more strip-shaped ferromagnetic materials can be wound from at least one coil (R; R1-R18).

Abstract: A novel method and apparatus to apply a corrosion protection in the form of a zinc (or other sacrificial anodic material) tape to a tubular member such as pipe or coiled tubing to used as an underground or underwater pipeline or flow line is disclosed. The zinc tape is applied with sufficient heat and pressure to form a metallurgical bond between the zinc tape and underlying metal pipe. This allows the zinc tape to act simultaneously as a continuous protective metal barrier to the normal scrapes and nicks the pipe experiences during installation and as a sacrificial anode. The novel apparatus preheats the zinc tape with a nozzle containing heated gas such as nitrogen as it approaches the pipe surface. At the point of contact with the pipe surface, the nozzle continues heating the tape and pipe surface while a plurality of pressure rollers exert sufficient force on the zinc tape to form a metallurgical bond between the zinc tape and the pipe surface.
