Abstract: A system to convey a fluid, in particular a fluid containing hydrocarbons, has a first pipeline, which is made of an electrically conductive material and has an internal diameter; a second pipeline, which is made of an electrically conductive material, has an external diameter smaller than the internal diameter, and is placed inside the first pipeline at a distance from the first pipeline so as to form an annular gap between the first and second pipeline; an electrically conductive layer placed in the annular gap at a distance from the first pipeline; an electrically insulating layer placed between the second pipeline and the electrically conductive layer; and a power source to apply an electrical potential difference between the second pipeline and the electrically conductive layer.
