Using an inhibitor to combat erosion-corrosion in carbon steel piping -- How much does it help?
- Univ. of Tulsa, OK (United States). Erosion/Corrosion Research Center
When sand, water, and CO{sub 2} gas are produced along with other production fluids, erosion-corrosion can occur in carbon steel piping and fittings. Metal loss rates in erosion-corrosion can be extremely high. The term ``threshold velocity`` is sometimes used to define a limiting flowstream velocity above which erosion-corrosion takes place. Threshold velocities depend on a number of factors such as temperature, solution composition (including pH), sand size, and pipe size. Sometimes desired production velocities are above threshold velocities and costly erosion-corrosion is a risk. But, in some cases, using a corrosion inhibitor can prevent erosion-corrosion damage by shifting threshold velocities to above production velocities. This paper describes how a laboratory flow loop and an erosion prediction model have been used to quantify the effect that using a corrosion inhibitor can have on the threshold velocity. Several examples of how the results of this research can be applied to oilfield problems are provided.
