ABSTRACT:
A device electrically connects fluid-carrying pipelines, particularly subsea pipelines carrying viscous fluids and/or containing organic residues, allowing for the application of electricity through same, with the purpose of heating those pipelines, so as to prevent or eliminate deposits of organic residues onto the internal walls of the pipelines. The device permits also the utilization of electricity in combination with the simutaneous injection of special fluids. Basically, it includes an electrically conducting pipe (5) which is introduced in a terminal pipe (1) carrying viscous fluid, which is put in contact with the internal steel layer (3) of the terminal pipe (1) by means of electrically conducting fastening element (8).
