pourbaix diagram for hp 13cr stainless steel in the aggressive Oilfield Environment characterized by high temperature high co2 partial pressure and high salinity
Electrochimica Acta, 2019Co-Authors: Yang Zhao, Tao Zhang, Dake Xu, Guanxin Zeng, Fuhui WangAbstract:Abstract The Pourbaix diagram for HP-13Cr stainless steel (SS) in the aggressive Oilfield Environment has been revised. Extrapolation of thermodynamics data to elevated temperatures has been performed with the revised model of Helgeson. The area of the corrosion of HP-13Cr SS and the pH value of Environment have been calibrated on the Pourbaix diagram using electrochemical measurements and surface analysis. The results indicated that the quinary Pourbaix diagram (Fe-Cr-H2O-Cl--CO2) can be obtained by the overlap of three ternary Pourbaix diagrams, i.e., Fe-Cr-H2O, Fe-Cr-Cl- and Fe-Cr-CO2 and the operational area located in the passivity region composed of Cr2O3 and Cr(OH)3(s).

investigation of the rotation speed on corrosion behavior of hp 13cr stainless steel in the extremely aggressive Oilfield Environment by using the rotating cage test
Corrosion Science, 2018Co-Authors: Yang Zhao, Tao Zhang, Dake Xu, Xuanpeng Li, Cheng Zhang, Guanxin Zeng, Fuhui WangAbstract:Abstract The influence of rotation speed on the scale film and pitting mechanism of HP-13Cr SS in high temperature (>180 °C), high salinity (Cl− concentration >60,000 mg/L) and high CO2 pressure (>4 MPa) Oilfield Environment was investigated using surface analysis and electrochemical techniques. The results delineated rotation speed decreased the mechanical properties and volume fraction of the amorphous Cr(OH)3(s) of the scale film. As a result, rotation speed increased the both nucleation susceptibility and growth probability of pitting, the serious pitting corrosion occurred and the geometry changed to shallow-disk shape.

Eco-friendly 2-Thiobarbituric acid as a corrosion inhibitor for API 5L X60 steel in simulated sweet Oilfield Environment: Electrochemical and surface analysis studies
Scientific Reports, 2019Co-Authors: Bashir J. Usman, Zuhair M. Gasem, Saviour A. Umoren, Moses M. SolomonAbstract:The corrosion inhibition efficiency of 2-Thiobarbituric acid (TBA) for metal substrate (API X60 steel) in 3.5% NaCl solution saturated with CO_2 gas was probed using various techniques namely, LPR (linear polarization resistance), EIS (electrochemical impedance spectroscopy), and PDP (potentiodynamic polarization). The effects of TBA concentration (25–100 ppm), solution pH (4 and 6), temperature (25–80 °C), and immersion time (2–72 h) on the inhibition efficiency were examined. SEM (scanning electron microscopy) and XPS (X–ray photoelectron spectroscopy) were deployed to explore the corrosion retardation mechanism. TBA exhibited protection efficiencies exceeding 90% for all experimental conditions considered. The excellent anticorrosion performance by TBA was retained up to 72 hours of immersion time. PDP results exhibited that TBA behaved as a mixed type inhibitor. Results from kinetics and thermodynamics analyses indicate that TBA chemically adsorbed on the steel surface following Langmuir isotherm model. The composition of the adsorbed TBA film has been analyzed by XPS.
