Assessment of a corroded pipe is crucial to determine when it must be repaired or replaced. However, the conventional corrosion assessment codes for failure pressure predictions pipes with circumferentially aligned interacting defects are conservative (underestimations more than 40%), resulting in premature repair replacements pipelines. Alternatively, numerical approaches may used, but they ti...

The impact of pre-corrosion on the performance an imidazoline-based corrosion inhibitor was evaluated with respect to inhibition uniform and localised in CO2-environments. Corrosion protection found be a function two factors, adsorption/film formation presence products. This effect most significant continuous FeCO3-rich layer high coverage steel surface, resulting only providing ?25 % overall a...

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 m...

abstract in this research, a radial basis function artificial neural network (rbf-ann) model was developed to predict the hot deformation flow curves of api x65 pipeline steel. the results of the developed model was compared with the results of a new phenomenological model that has recently been developed based on a power function of zener-hollomon parameter and a third order polynomial functio...
