Corrosion resistance of some welding-on metallic coatings for downstream oil production
equipment corrosion control is discussed. It is shown, that cathodic coating with satisfactory general corrosion resistance cannot be recommended for use owing to they are porous. Necessity of discriminate in corrosion control evaluating is underlined.
