Parametric Study of the Corrosion of API-5L-X65 QT Steel Using Potentiostat Based Measurements in a Flow Loop

Low-carbon steel is widely used in industrial pipelines, and corrosion studies are focused mostly on erosion-corrosion, its prediction control. In this paper, the rate pipelines modeled using a flow loop measured by linear polarization resistance method (LPR) 3-electrode setup for API-5L-X65 QT steel. Optical microscopy SEM conducted to examine surface of sample products. The effect NaCl concentration studied at different pH, temperature range, velocities with dissolved oxygen content solution maintained 6 mg/L (6ppm). found be varying from 1 mil per year (0.0254 mmyr?1) 10 mils (0.254 mmyr?1), increases velocity reaches maximum Reynolds Number above 10,000. Further increase fluid shows insensitive, uniform predominant region.
