  • Patent number: 5670041
    Abstract: A method for minimizing localized corrosion of fluid containers that occurs as a consequence of most non-chemical procedures for removing scale deposits is described. It counteracts the unavoidable side-effect of the lowering of the local pH in the vicinity of the bubbles of CO.sub.2 that are generated during an electromagnetically-induced controlled precipitation procedure. The method is a simple and facile procedure for curbing the localized corrosion occurring as a result of most non-chemical procedures for removing scales. The method is desirably performed by an induction coil wrapped around a fluid container such as a pipe encrusted with scale through which hard water is flowing. A pulsing electrical current is successively applied through the coil and halted, preferably for 3 to 10 minutes each. When the current is applied, a transitory induced magnetic field is generated in the solution, and scale encrusted on the fluid container dissolves in the solution.
