A corrosion coupon is a simple and very effective tool that gives a quantitative estimate of corrosion rates that take place within a specific environment. 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 equipment failure
Corrosion coupons provide a cost-effective means of monitoring that allows corrosivity measurement in a system in the most accurate manner. This is usually done through the observation of the corrosion rate in mils per year of a coupon exposed in the system. With this, valuable data can be extracted about the life expectancy of materials.
