发明名称 Electrical heating system for subsea flexible pipelines.
摘要 <p>This invention relates to an electric heating system for subsea flexible pipelines (13) including the circulation of an electric current through the metallic armourings (31) of the flexible pipeline (13), generating energy and dissipating a certain amount of heat to the pipeline (13) and to the fluid flowing therein, maintaining the temperature differential between the environment and the production line, so as not to interrupt the fluid flow. <IMAGE></p>
