Corrosion Coupons
Accurate monitoring of corrosion rates in any environment is critical when viewed in terms of the maintenance and repair costs associated with corrosion and material failure. Test coupons provide an inexpensive means of on-line monitoring that will allow you to effectively measure the corrosivity within your system. By observing the mils-per-year corrosion rate of an exposed coupon, valuable information can be provided regarding the material’s life expectancy.

Perisco can make coupons in any size, shape, or material you need. Coupons can be stenciled with alloy and sequence numbers for proper identification. Mill test reports, identifying element compositions of materials used, are provided on all orders.

Note: When ordering test coupons, please be ready to provide the sales person with information regarding the type of material you are testing, the style and size of the coupons you require, surface finish desired, and if applicable, mounting hole size and location.
