1 Measuring Corrosion and Corrosion Control (CC) on Water Pipe Materials Graham E.C. Bell, Ph.D., P.E. Water/Wastewater Forum Corrosion: Why Should I Be Concerned? Corrosion 2010/San Antonio CC in the Water Industry is Fundamentally Different from CC in Oil & Gas Pipe Materials, Coatings and Linings CIP, DIP, Steel, and Reinforced/Pre-stressed/tension Concrete Mortar and Concrete Coatings and Linings Push-on NOT Welded Joints Lack of Regulatory Requirement for Corrosion Control and Monitoring. Cathodic Protection is the last resort of a desperate water corrosion engineer. Corrosion Control tends to be more passive and buried with the asset. Ferrous Pipe Materials Steel Pipe AWWA C200 Dielectric Coating AWWA C203 AWWA C210 AWWA C214 AWWA C222 Ductile Iron Pipe AWWA C151 AWWA C105 1
2 Mortar/Concrete Encased Steel Mortar Coated Steel Pipe AWWA C200+C205 Concrete Pipe AWWA C300 AWWA C301 AWWA C302 AWWA C303 Focus on Corrosion Monitoring Oil & Gas Corrosion Monitoring Focuses on Adequacy of Cathodic Protection for Compliance. Water Industry focuses on asset preservation and capital conservation Measuring -850 is not sufficient in the Water Industry Regulatory Compliance monitoring is fundamentally different. NACE standards focus on measurement of pipe or structure to electrolyte potential measurements (SP-0169). Asset Preservation and Capital Conservation Requires measuring corrosion damage or corrosion rate. Fundamentally, we need to measure corrosion current (i corr ) or mils lost. 2
3 Use of CP with Ferrous Water Pipe Materials is Spotty More common on NEW large diameter steel transmission pipelines with dielectric coatings. Retrofitting of existing ferrous pipelines occurs when leak rates become unacceptable. CP of DIP is a controversial subject. Most DIP is installed with out protection Small percentage with polyethylene encasement (PE) Even smaller percentage installed with PE and CP or even just CP. Surrogates Methods for Measuring Corrosion Coupons Probes Electrical Resistance (ER) Electrochemical Techniques Linear Polarization Advanced Electrochemical Methods Principals of Operation for ER Probes Thin cross section of metal corrodes. As metal thins uniformly, resistance of the strip increases. Changes in resistance of strip record metal loss (corrosion damage) Slope of line is the corrosion rate. 3

8 Linear Polarization Resistance (LPR) LPR is a measurement technique that provides a direct electrochemical measurement of corrosion rate in a conductive electrolyte (soil or water) The measurement is made from two small electrodes made from the material (metal or alloy) of interest. The determination of the corrosion rate is calculated from a series of electronic measurements The LPR Equivalent Circuit R P R P Electrode 1 R S Electrode 2 C dl C dl R P = Polarization Resistance R s = Solution Resistance C dl = Double Layer Capacitance The behavior of a metal in an electrolyte 8

12 Other Possible Electrochemical Measurements Electrochemical Impedance Spectroscopy (EIS) Electrochemical Noise (EN) Etc., etc.,. The point is that we can measure and estimate corrosion rates on ferrous metals very well and relatively accurately using surrogates. Design and Long Term Current Requirements for Water Pipe Materials Conclusions Motivation for Corrosion Control is Different in Water and Wastewater than it is in Oil & Gas Asset Preservation requires measuring corrosion rates rather than assuring compliance. We can measure corrosion rates using surrogates. Data need to be turned into actionable information. If you are not going to do anything, remain ignorant. 12
