An electrochemical study of three API steels: X52, X65, and X80, exposed to seawater and sediment from seabed is presented. Two seabed samples were collected at 60 meters depth near a platform (seabed A) and at a distance of 500 m (seabed B) from the same platform of the Sonda of Campeche, Mexico. In both samples, the seawater and sediment were separated in order to characterize their corrosiveness in an electrochemical cell of 100 mL. The physicochemical and electrochemical responses were deter...

The effect of different cathodic potentials applied to the X70 pipeline steel immersed in acidified and aerated synthetic soil solution under stress using a slow strain rate test (SSRT) and electrochemical impedance spectroscopy (EIS) was studied. According to SSRT results and the fracture surface analysis by scanning electron microscopy (SEM), the steel susceptibility to stress corrosion cracking (SCC) increased as the cathodic polarization increased (Ecp). This behavior is attributed to the an...

The purpose of this paper is to study the effect of heat treatment (HT) applied to an API X60 steel in corrosion resistance and stress corrosion cracking (SCC) susceptibility through slow strain rate tests (SSRT) in NS4 solution and congenital water (CW) to assess external and internal SCC, respectively.,API X60 steel was heat treated at a temperature of 1,200°C for 30 min followed by water quenching. Specimens from this steel were machined according to NACE TM 198. SSRT were performed in a cons...

Purpose The purpose of this paper is to study the corrosion rate for X52, X60, X65, X70 and X80 steel immersed in Mexican oilfield produced water. For the electrochemical characterization of the five steels rotating disk electrodes, 20°C, 30°C and 45°C of experimental temperature and 0, 500, 1,000 and 2,000 rpm of rotation speed were taken into account. The temperature dependence was analyzed using Arrhenius law. Thus, Rct values obtained from EIS data in comparison with the corrosion rate obtai...

Se ha llevado a cabo un estudio de la susceptibilidad al agrietamiento por corrosion y esfuerzo (SCC) del acero de tuberia API X70 expuesto a una solucion sintetica de agua del suelo a temperatura ambiente y a presion atmosferica y se han utilizado pruebas a baja velocidad de deformacion (SSRT). Las mediciones de ruido electroquimico (EN) se registraban durante las SSRT con el objetivo de estudiar el proceso de SCC. Adicionalmente, se llevaban a cabo las curvas de polarizacion (PC) para evaluar ...

Purpose The purpose of this paper is to study the susceptibility to corrosion processes of X60, X65 and X70 steels immersed in sand-clay soil with pH 3.0, using electrochemical techniques, scanning electron microscopy (SEM), energy dispersive spectroscopy and X-ray diffraction (XRD). Design/methodology/approach Natural acidic soil sample was collected as close as possible to buried pipes (1.2 m in depth) in a Right of Way from south of Mexico. Both steels and soil were characterized through SEM ...
