“…The impingement system has been extensively used [17][18][19][20][21][22][23][24][25][26][27] to study the influence of the different parameters on erosion-corrosion. The erosion-corrosion resistance of carbon steel in CO 2 containing environments has also been widely investigated [28][29][30][31]. This paper focuses on the impact of sand loading and velocity on the erosion-corrosion of mild steel by the impingement test in an aqueous slurry.…”

The presence of CO2, sand, and water in oil and gas reservoirs causes erosion–corrosion leading to material degradation in pipelines and fluid handling equipment that results in increasing maintenance and repair costs and a decrease in production. While the weight loss caused by erosion–corrosion is known to depend on flow velocity, angle of impact, sand loading and size and target material properties, field operators often limit the flow rate based on a critical corrosion velocity to protect the equipment. This study investigates the effects of sand loading and flow velocity on weight loss associated with erosion–corrosion in a mild steel sample using a submerged impingement jet. The weight loss by erosion, corrosion and their interaction for a flow velocity range of 10 m/s to 20 m/s and sand loading range of 300 mg/L to 600 mg/L, in a seawater environment, are presented. The results showed that the weight loss by pure erosion and erosion–corrosion interaction increases linearly with jet velocity and sand loading, and that erosion is dominant in all cases except at low velocity and sand loading. The scanning electron microscope (SEM) images after impingement tests were analyzed. In addition, correlations for the velocity and sand loading were derived using the design of experiment method (DOE).

“…Similar observations were made by Paolinelli et al [7] and Zhang et al [8] who reported that an increase in pre-corrosion time led to a decrease in inhibitor efficiency which was attributed to the formation of corrosion products. However Senatore et al [9] observed a notable synergistic interaction between the inhibitor and the corrosion product in providing protection against erosion-corrosion.…”

Performance evaluation of an imidazoline corrosion inhibitor in a CO2-saturated environment with emphasis on localised corrosion

et al. 2020

The ability of an imidazoline inhibitor to provide corrosion protection to X65 carbon steel in a CO2-saturated sodium chloride (NaCl) solution at 80 º C was evaluated. The performance of the inhibitor was investigated with respect to both generalised and localised corrosion behaviour using in-situ electrochemical measurements, ex-situ scanning electron microscopy (SEM) and non-contact surface profilometry. We demonstrate that the optimum inhibitor concentration required to minimise generalised corrosion is significantly lower than that required to minimise localised corrosion. This highlights the importance of systematic, post-test topographical measurements in the selection and optimisation of inhibitor dosage.

“…Particularly, when solid particles are entrained to corrosive flow medium, the pipelines bear erosion and corrosion simultaneously, and erosion-corrosion (E-C) will be aggravated [6,7]. Owing to the synergism between erosion and corrosion, which is the coupling between electrochemical and mechanical processes, it is challenging to authentically grasp the essential origins of the material failure and dependably forecast the lifespan of pipelines [8][9][10].…”

Electrochemical measurements and surface analysis are performed to comparatively study flow-accelerated corrosion (FAC) and erosion–corrosion (E-C) behavior at a 90° carbon steel bend. The corrosion rates are higher under FAC conditions than those under E-C conditions. For FAC, the corrosion is more serious at the inside wall. However, corrosion is exacerbated at the outside wall under E-C conditions. No erosion scratches are observed under FAC conditions and at the inside wall under E-C conditions, while remarkable erosion scratches appear at the outside wall under E-C conditions. The dominant hydrodynamics affecting FAC and E-C are remarkably different.
