Corrosion behavior of N80 carbon steel in CO2 environments: Investigating the role of flow velocity and silty sand through experimental and computational simulation
Source abstract
Abstract
The effects of flow velocity and silty sand on CO 2 corrosion of N80 carbon steel were studied using a small flow loop. Silty sand does not change the electrochemical characterization of corrosion but reduces the corrosion rate of steel. Under the low flow velocity, silty sand embeds in the sample surface, reducing active area for iron dissolution and delaying the formation of FeCO 3 in corrosion product layer. At medium and high flow velocity, silty sand erodes the sample surface, and wall shear stress damages the integrity of the corrosion product layer, but do not lead to greater corrosion rate.
