carefully mount the coupons on the holder arms. . Even so, many facilities require coupon studies and below is the detailed procedure for installing and monitoring coupons. Use the table below to evaluate the results from your study. Store the coupon envelopes in the controller or in a dry place near the coupon rack. Flow rates in excess of 5 fps will erode soft metals such as copper and brass. . Cosasco standard corrosion coupons are furnished with a ground surface finish or directional sanded surface finish. All coupons are furnished as machined unless otherwise specified. The exception is Cosasco standard G10180 which is annealed. What Do, corrosion, coupons Do? Conversely, installing the coupon rack after the tower will result in lower corrosion rates.
It is designed to penetrate the seams and crevices.

These coupons also offer a visual signal of the corrosion type that may be occurring in the system under observation.
Inconsistent flow will cause higher corrosion results. Cosasco coupons are individually packaged in moisture resistant, vapor phase inhibited envelopes with a corrosion free shelf life of one year. Cosasco corrosion and erosion metal loss monitoring coupons are specially made for corrosion and erosion studies and are manufactured to the most demanding standards. Place the coupon into the original envelope without the plastic bag. . Hardware for these coupons is furnished with the corrosion coupon holders. . It prevents rust and corrosion in all metals, it protects vinyl and plastic surfaces from UV rays and improves the function of moving goodnites coupon parts through lubrication.
