Corrosion Behavior of Carbon Steel X36 in Solutions of Soils Collected from Different Areas Linked to the Main Pipe Network of a Water Distribution System in Jeddah City

The corrosion behavior of carbon steel X36 (CSX36) in solutions soils collected from different areas linked to the main pipe network a water distribution system Jeddah City (Obhour Al Shamaliyah, Ob-Sh; Shateie, Sh; Safa, Sf; Samer, Sa; and Jameaah, Ja) at an ambient temperature (23 ± 1 °C) was studied. monitored using various techniques, such as weight loss electrochemical (open circuit potential [OCP]; impedance spectroscopy; potentiodynamic polarization) measurements. Visual microscopic examinations surface morphology studied metals were evaluated discussed. rates all soil decreased with increase immersion period over 80 weeks. corrosivity based on measurements followed order Sh > Ja Ob-Sh Sa Sf. value OCP gradually shifted more negative values, indicating higher tendency corrode. For studied, Ecorr that process under cathodic control. values icorr 1/Rp tended resistivity decreased. Moreover, there good consistency between solution obtained spectroscopy PDP following order: A comprehensive assessment variables revealed are extremely corrosive, while rest noncorrosive.
