METHOD AND APPARATUS FOR PURIFYING INNER WALL OF METAL PIPING SYSTEM BY ELECTROLYTIC POLISHING

摘要

1. Method for cleaning the inner walls of metallic pipework systems by electropolishing using mobile electrodes, wherein the electrolyte is filled into the pipework system, with the electrode applied to a sector of the pipework wall by means of about 5 MPa high pressure, and the cathode moved in the pipework system by means of the high pressure jet.
