CA 2049906
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 simultaneous 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).
Un dispositif servant à la connexion électrique des pipelines transportant des fluides, particulièrement les pipelines sous-marins transportant des fluides visqueux et/ou contenant des résidus organiques, ce qui permet l'utilisation de l'électricité pour chauffer les pipelines, de manière à prévenir ou à éliminer les dépôts de résidus organiques sur les parois internes des pipelines. Ce dispositif permet également l'utilisation de l'électricité avec l'injection simultanée de fluides spéciaux. Il comprend fondamentalement un tuyau conducteur (5) introduit dans un tuyau de terminal (1) transportant le fluide visqueux et mis en contact avec la couche interne d'acier (3) du tuyau de terminal (1) au moyen d'un élément de fixation conducteur (8).
