The invention relates to a segment designed to be fitted by screw-fastening for implementing a fluid transport pipe for transporting a fluid, which pipe comprises an inner wall and an outer wall, the segment comprising an inner tube and an outer tube that define an annular space between them, the segment comprising in particular one heating duct placed in its annular space and opening out at either end of its annular space, said annular space being designed to be closed hermetically in order to enable it to be brought to a reduced pressure. The invention relates further to a method of manufacturing said segment and a method of implementing said fluid transport pipe.
A segment designed to be fitted by screw-fastening for implementing a fluid transport pipe for transporting a fluid, which said pipe comprises an inner wall and an outer wall, said segment comprising an inner tube and an outer tube that define an annular space between them, wherein said segment comprises at least one heating duct placed in said annular space and opening out at either end of said annular space, said annular space being designed to be closed hermetically in order to enable it to be brought to a reduced pressure.
A fluid transport pipe for transporting a fluid, which pipe is made up of adjacent segments designed to be fitted by screw-fastening for implementing a fluid transport pipe for transporting a fluid, which said pipe comprises an inner wall and an outer wall, said segment comprising an inner tube and an outer tube that define an annular space between them, wherein said segment comprises at least one heating duct placed in said annular space and opening out at either end of said annular space, said annular space being designed to be closed hermetically in order to enable it to be brought to a reduced pressure.
A method of manufacturing segments designed to be assembled together end-to-end by screw-fastening for the purpose of implementing a fluid transport pipe comprising an inner wall and an outer wall, which method comprises the following steps for fitting each segment:
