ELECTRODE DEVICE FOR ELECTRICALLY HEATING UNDERGROUND DEPOSITS OF HYDROCARBONS

摘要

14-25432M/KH/81 An electrode device for electrically heating underground deposits of hydrocarbons in which an insulated pipe is disposed between an electrode and a main guide pipe. The two end portions of the insulated pipe are formed as flanges having outer circumferential surfaces counter tapered to diverge at a predetermined angle toward the end portions. Shock absorbers are disposed between fastening fixtures and the counter-tapered surfaces of the insulated pipe and the fastening mixtures are coupled to connectors on the main guide pipe and the electrode through bolts. If desired, the abutting surfaces of the main guide pipe and the electrode can be formed counter tapered similarly to the counter-tapered surfaces of the insulated pipe.
