Corrosion as a Real-time Process Variable

Corrosion evaluation methods used by expert corrosion engineers often involve analysis of sacrificial samples (coupons) placed in the pipeline. These samples are precisely weighed prior to exposure to the process media, analyzed for metal loss and other imperfections, and serve as the basis for determining general and localized corrosion rates for the process.
