“…When the shear stress is large enough, the resultant mechanical effect will change, therefore, the effect of impact angle on flow corrosion also cannot be ignored. Khayatan et al 11 studied that the maximum erosion and corrosion rate of pure titanium (CP-Ti) occurred at an impact angle of 40°, and its rate is significantly higher than the pure erosion rate under the positive synergy of all impact angles. Burstein et al 12 also showed that the Al activity decreased with the increase of the fluid impact angle, and the increase of impact angle would decrease the electrode area under high velocity flow field and increase under low velocity flow field.…”

The self-designed flow system was used to study the flow corrosion of X100 pipeline steel in simulated formation water environment by electrochemical measurements as well as computational fluid dynamics (CFD) simulation. The effects of fluid flow velocity and fluid impact angle on X100 steel were determined. When the fluid flow velocity changes between 0.5-2.0 m/s, X100 steel is controlled by activation, and as the flow velocity increases, the self-corrosion current I corr increases, the corrosion rate increases; when the impact angle increases from 30°to 90°, the self-corrosion current I corr decreases and the corrosion rate decreases. CFD simulations show that at different flow velocities and impact angles, the velocity field distribution on electrode surface is different. At the minimum impact angle of 30°, the electrode area has the largest flow velocity and shear stress, therefore the corrosion damage is the most serious.

“…Corrosion under fluid flow, which will cause wall thinning and an even perforation of pipelines, is a major issue in oil and gas production [1][2][3]. Corrosion under fluid flow usually gives rise to the premature failure of flow parts and the bankruptcy of oil and gas enterprise, resulting in tremendous pecuniary loss, environmental pollution, and security, lurking peril [4,5].…”

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.
