At the end of the fixed period, the corrosion coupon is removed from the process environment and analyzed for the time averaged General Corrosion Rate, Pitting Corrosion, sessile bacteria and solids if required. Of importance with corrosion coupon monitoring is the placement within the process and within the infrastructure to provide representative results. Corrosion coupons provide an economical approach to internal corrosion monitoring and material evaluations. Rysco Corrosion Services are available to provide equipment sales, manufacturing, data interpretation, lab analysis, and field services in support of weight-loss corrosion coupons.
