Description
A corrosion coupon is a small, pre-measured metal sample used to evaluate the rate and type of corrosion occurring in a specific environment. Typically, these coupons are made from the same material as the equipment or pipeline being monitored. Therefore, the corrosion data accurately reflects real-world conditions. As a result, engineers can make informed decisions about maintenance and corrosion prevention strategies.
Once placed in the system, they are exposed to the operating conditions for a set period. Afterward, they are retrieved and analyzed for weight loss, pitting, or other signs of degradation. Ultimately, corrosion coupons provide valuable insights that help industries implement effective corrosion control measures and maintain equipment longevity.
After retrieval, they are analyzed for weight loss, pitting, or other signs of degradation, providing valuable data on corrosion rates and potential risks. Corrosion coupons are widely used in industries such as oil and gas, water treatment, and chemical processing to assess the effectiveness of corrosion control measures and optimize maintenance strategies.

Corrosion Coupon Applications
Corrosion coupons are widely used in industries where metal structures, pipelines, and equipment are exposed to harsh environments that can cause material degradation. In the oil and gas industry, they are placed inside pipelines and storage tanks to assess the impact of corrosive substances such as hydrogen sulfide, carbon dioxide, and water.
By regularly analyzing these coupons, companies can effectively determine the effectiveness of corrosion inhibitors and protective coatings, thereby helping to prevent costly failures and extend the lifespan of critical infrastructure. Similarly, in water treatment facilities, corrosion coupons are also used to evaluate the aggressiveness of treated water on distribution systems, thus ensuring that pipes and tanks remain in good condition over time.
In the chemical processing industry, corrosion coupons help monitor the impact of acidic or alkaline solutions on plant equipment, allowing for proactive material selection and maintenance planning. Power plants also use corrosion coupons to assess the effects of high temperatures, steam, and cooling water on boiler systems and heat exchangers.
Additionally, in marine environments, where metal structures are constantly exposed to saltwater and humidity, corrosion coupons help evaluate protective coatings and cathodic protection systems. Furthermore, by using corrosion coupons in these various industries, engineers and maintenance teams can collect valuable data to improve corrosion prevention strategies, enhance safety, and ultimately, reduce repair costs.
