Thickness loss coupons are metal strips that are used to measure the corrosion rate of a specific material or environment. They are a type of strip corrosion coupon that are commonly used in various industries, including oil and gas, petrochemical, and marine, to evaluate the corrosion resistance of materials, coatings, and treatments, and to monitor and control corrosion in real-world conditions.

Thickness loss coupons consist of a metal strip with a defined surface area that is exposed to the environment being tested. The strip is measured for thickness before and after being exposed to the environment, and the change in thickness is used to calculate the corrosion rate. The thickness loss is expressed as a function of surface area and time, typically in units of millimeters per year (mm/yr).

Thickness loss coupons provide valuable information about the corrosion rate of materials and the influence of environmental conditions, such as temperature, humidity, fluid flow, and the presence of inhibitors, on the corrosion rate. They are particularly useful for evaluating the corrosion resistance of materials with a uniform composition and for monitoring the corrosion rate over a longer period of time.

It is important to carefully control and monitor the conditions during thickness loss coupon tests to obtain accurate results and to determine the influence of different factors on the corrosion rate. Additionally, it is important to carefully select the coupon material and surface area, as well as the duration of the test, to ensure that the results are representative of the actual corrosion rate in the environment being tested. Accurate measurement of the thickness of the coupon after exposure to the environment is critical to obtain accurate results, and specialized equipment, such as a surface profilometer, may be required to achieve the necessary level of accuracy.

Some of the advantages of strip corrosion coupons include:

1. Easy to install and remove: Strip corrosion coupons are simple to install and can be easily removed for analysis.
2. Cost-effective: Strip coupons are a cost-effective way to monitor corrosion as they are relatively cheap compared to other corrosion monitoring methods.
3. Accurate measurement: Strip coupons provide an accurate measurement of the corrosion rate, allowing engineers to make informed decisions about corrosion control measures.
4. Versatile: Strip coupons can be used in a variety of environments, including corrosive liquids and gaseous atmospheres, making them a versatile tool for monitoring corrosion.
5. Repeatable: Strip coupons can be installed and removed multiple times, allowing for repeated measurements over time to track changes in the corrosion rate.
