INDUCED AC INFLUENCE ON PIPELINE CORROSION AND COATING DISBONDMENT. FINAL REPORT, NOVEMBER 1993-SEPTEMBER 1994
Gas transmission pipelines often share a common corridor with electric power transmission lines. Magnetic-field coupling from the power line can induce AC voltage between the pipeline steel and the earth. With induced AC voltage on the pipeline, conditions that influence AC-enhanced corrosion and the efficacy of recognized cathodic-protection criteria are unknown. A preliminary laboratory investigation of general and pitting corrosion-rate enhancement by superimposed 60 Hz voltage, and the effectiveness of a recognized cathodic-protection criterion has been made.
