Abstract
A pipe having at least two steel pipe elements with internal lining that are assembled together end to end, with the ends of the two pipe elements being welded together. A tubular junction sleeve is interposed inside the pipe at the abutting ends of the two pipe elements so that the end terminal portions of the sleeve are at least in part in leaktight contact with respective ones of the terminal portions at the ends of the internal linings of the two pipe elements. The leaktight contact zone is a zone of fusion welding together the materials in mutual contact constituting at least a portion of each terminal portion of the sleeve and of each respective terminal portion of the lining. At each of the terminal portions of the sleeve in the leaktight contact zone, the tubular junction sleeve presents a Joule effect heater wire arranged in a double spiral on the outer surface of each terminal portion at the ends of the sleeve.
