Corrosion Coupon

SMARTCORR®  two-inch coupon corrosion monitoring system consists of Access Fitting, Coupon Holder, and Coupons. Corrosion coupons are one of the widest used methods for the study of corrosion and its effects. They are relatively small, easily inserted and retrieved, and are an economical means of determining cause and effect of corrosion.

Corrosion and erosion metal loss monitoring coupons are specially made for corrosion and erosion studies and are manufactured to the most demanding standards. Generally, corrosion coupons should be of an alloy the same as, or similar in chemical composition to the pipeline or vessel that is being monitored. We manufacture monitoring corrosion coupons in any configuration, and from any materials, whether provided by us or by the customer. Evaluation of welds can be made by utilizing corrosion monitoring coupons with weld beads applied, or evaluation of scale by use of strip scale coupons. All coupons are certified in writing to show serial numbers, weights (furnished in grams to four decimal points), dimensions, material, and surface finishes. SMARTCORR® coupons are individually packaged in moisture resistant, vapor phase inhibited envelopes with a corrosion free shelf life of one year.
