Validation of External Corrosion Growth-Rate Using Polarization Resistance and Soil Properties

The objective of this project is to estimate corrosion growth-rates, reduce assessment costs, and improve the selection of reassessment intervals of pipelines and increase their safety. This will be achieved by: (1) perform field tests and demonstrations using LPR and ER technologies; (2) correlate results with weight-loss of buried coupons; (3) evaluate soil parameters that affect corrosion; and (4) incorporate the measurements into a database and program that improves corrosion-rate estimates.
