CORROSION “The deterioration of a material, usually a metal, that results from a reaction with its environment.”
pH OXYGEN RESISTIVITY TEMPERATURE COATING PROPERTIES ELECTROLYTE MOISTURE CONTENT ANODE MATERIAL ANODE LOCATION ANODE SIZE ANODE SHAPE STRUCTURE MATERIAL BACTERIA OTHER MINERALS IN ELECTROLYTE SOME VARIABLES IN THE CORROSION CONTROL PROCESS
CORROSION CONTROL MEASURES • MATERIALS SELECTION • DESIGN CONSIDERATIONS • PROTECTIVE COATINGS AND LININGS • CATHODIC PROTECTION • INHIBITORS
SOME CP DESIGN CONSIDERATIONS • ELECTROLYTE RESISTIVITY • SYSTEM LIFE REQUIREMENTS • COATING EFFICIENCY • CURRENT REQUIRED FOR PROTECTION • ECONOMIC FACTORS • PHYSICAL CONFIGURATION OF STRUCTURE • MATERIALS USED IN STRUCTURE. • ANODE CHARACTERISTICS
CP CONSTRUCTION CONSIDERATIONS • PREPARATION OF METAL SURFACE FOR COATING • PROPER SELECTION AND APPLICATION OF COATING • PROCUREMENT OF CP EQUIPMENT MEETING SPECIFICATIONS • SUPERVISION OF INSTALLATION BY QUALIFIED PERSONNEL • ENERGIZING, ADJUSTMENT, AND TESTING BY QUALIFIED PERSONNEL
MAINTENANCE AND REPAIR CONSIDERATIONS • WEEKLY RECTIFIER READINGS RECORDED AND SENT TO DISTRICT CP SPECIALIST FOR REVIEW • ANNUAL PROTECTIVE POTENTIAL SURVEY PERFORMED BY QUALIFIED PERSONNEL • NECESSARY SYSTEM ADJUSTMENTS MADE BY QUALIFIED PERSONNEL • NECESSARY REPAIRS MADE AS SOON AS POSSIBLE AND RETEST IF NECESSARY
SUMMARY • THERE ARE MANY FORMS AND MECHANISMS THAT CAUSE CORROSION. • PROPER CORROSION CONTROL SAVES MONEY, AND IMPROVES OPERABILITY AND SAFETY AND PROTECTS THE ENVIRONMENT. • CATHODIC PROTECTION IS A PROVEN EFFECTIVE METHOD OF CORROSION CONTROL. • CORROSION CONTROL IS COMPLEX, REQUIRING SPECIAL EXPERTISE FOR SUCCESSFUL DESIGN, CONSTRUCTION, AND MAINTENANCE
