Global and local parameters for characterizing and modeling external corrosion in underground coated steel pipelines: A review of critical factors

External corrosion assessments of pipeline systems encompass two critical factors: time and space (location). Field measurement databases, laboratory testing, and theoretical prediction studies have been reported, based on continuous monitoring, survey and on-site characterization techniques, and controlled and simulated laboratory-scale environment studies. Theoretical models have identified several critical factors in assessing external...
