ABSTRACT:
Apparatus and method are disclosed for polishing the inner surface of a metallic tubing. The apparatus includes a container for retaining electrolytic solution and pump means for circulating the electrolytic solution from the container through the metallic tubing to be cleaned. A dc power supply means is provided having a negative terminal which is coupled to a cathode member of a cathode assembly. The assembly also includes a porous material cover over the cathode member. The cathode assembly is sized for insertion within the tubing without completely blocking the flow of electrolytic solution through the tubing. Clamp means is provided for forming electrical connection between the positive terminal of the dc power supply and the metallic tubing to be cleaned. When the clamp means is secured to the metallic tubing and the cathode member is positioned within the tubing, electropolishing occurs on the inner surface of the tubing. Various specific methods are also described based upon the particular cathode assembly configuration used.
