Acidic corrosions for oil and natural gas pipelines have been investigated by studying the effect of sulfuric acid (H2SO4) on carbon steel surface sample. Three different concentrations of sulfuric acid (0.1, 1, and 2 M) and two distinct kinds of carbon steel were used in this research. The results demonstrates that when the concentrations of acid medium (H2SO4 solutions) increased, the corrosion rates also increased due to the effect of high concentration of the acid. In addition, kinetic of corrosion rates were studied in which the corrosion rates followed the pseudo first order from the values of R2 for the samples. Furthermore, polymer electrolyte liquid of polymethyl methacrylate (PMMA) has been used to decrease the acidity strength. The PMMA was indicated that the medium acidity decreased leading to supply further protection from corrosion. These results can be applied to successfully manage pipelines and improve the pipeline protection in acidic corrosion condition. Likewise, polymer electrolyte liquid PMMA oligomer should be considered as a novel form in polymer electrolyte field that might be employed in electrochemical devices for corrosion control purposes in acid media.
