A heat-generating pipe arrangement utilizing skin effect current includes a ferromagnetic pipe and an insulated conductor line passing through the interior of the pipe and having such a circuit therewith that current is concentrated and passed only through the inner surface of the pipe when an alternating current is passed through the circuit. The heat-generating pipe is spaced apart from the outside wall of a pipeline to be heated by interposed spacing means whereby a small clearance of about a millimeter is created and maintained over the entire length of the ferromagnetic pipe to protect the pipeline from being damaged by a possible arc in the event of a failure of the insulation on the conductor inside the ferromagnetic pipe. |
