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.

Metal Samples 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.

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.

Corrosion coupons are one of the longest 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.

A corrosion coupon is a simple and very effective tool that gives a quantitative estimate of corrosion rates that take place within a specific operating system. These coupons also offer a visual signal of the corrosion type that may be occurring in the system under observation.

This tool can greatly help in precise corrosion rate monitoring in any critical environment. It is beneficial in terms of:

• Repair costs
• Maintenance
• Measurement of material failure

Corrosion coupons are also known as corrosion monitoring coupons.

Corrosion coupons are generally used in weight loss tests. Properly selected, such coupons will provide quantitative estimates of corrosion rates as well as physical evidence of the type of corrosion occurring in the process environment. In order to provide reproducible data, selected coupons must have a uniform shape, size, surface area, and surface finish. Coupons should be fabricated of an alloy that is similar in composition to the process equipment of interest.

NACE has published a Recommended Practice RP-0775 entitled Preparation and Installation of Corrosion Coupons and Interpretation of Test Data in Oil Production Practice.
