ABSTRACT:
An apparatus for internally electropolishing tubes in which a plurality of elongate tubes are horizontally supported and rotatably driven about their length axes. An outlet fitting including an end dam permits rotation of the tube outlet end therein, allows escape of gases from the upper portion of the tube, and permits overflow of electrolyte liquid thereover and fixedly supports the end of a cathode rod. The cathode rod is formed as two aligned, axially adjacent partial length sections. The positive terminal of an electric current supply connects at a plurality of points to the tube along its length and connects at its negative terminal individually to the outer ends of the two cathode sections.
