Effect of Magnetic Field on the Corrosion of API-5L-X65 Steel Using Electrochemical Methods in a Flow Loop

Limited studies have been conducted on the effect of a magnetic field corrosion behavior steels. Investigating pipeline material in oil and gas industries will be beneficial regarding prediction control. In this work, process API 5L X65 carbon steel was investigated well-developed flow loop using potentiodynamic polarization curves electrochemical impedance spectroscopy (EIS). Using permanent magnets well-designed electrode set-up, mechanism studied at different orientations conditions NaCl solution. The surface morphology corroded samples scanning electron microscope, micro-morphologies deposits elemental composition were analyzed. results show that presence increases rate steel, velocities orientation significant influence anodic current. indicate negative shift Tafel curve, leading to an increase with introduction system. EIS charge transfer is decreased when applied. This work provides important direction terms understanding combined magnetism pipelines used industries.
