Abstract
A segment is fitted by screw-fastening for implementing a fluid transport pipe for transporting a fluid, the pipe including an inner wall and an outer wall, the segment including an inner tube and an outer tube that define an annular space between them. The segment includes in particular one heating duct placed in its annular space and opening out at either end of its annular space, the annular space being designed to be closed hermetically in order to enable it to be brought to a reduced pressure. A method of manufacturing the segment and a method of implementing the fluid transport pipe is described.
