Abstract

PURPOSE: To perform an electrolytic protection treatment without allowing protective layers to peel by forming the protective layer consisting of a mixture of a malleable elastic material and a phenolic resin on the surfaces of a steel pipe.
CONSTITUTION: Mixed solns. consisting essentially of both of a malleable elastic material such as non-polar rubber like natural rubber or butyl rubber dissolved in a solvent and a phenolic resin added thereto at about 1:0.2W6 (weight ratio) are prepd. A metallic product such as steel pipe is treated by using such mixed solns., whereby a protective film is formed on the surfaces thereof. In spite of conduction of electricity of this coated metallic article for the purpose of electrolytic protection, it does not cause cathode peeling, and the sufficient corrosion preventive effect is obtained over a long period of time. This method is adapted to corrosion prevention of steel pipes and the like for pipelines.
