Abstract

The organic coating systems for protection against internal corrosion of pipelines have recently received considerable attention due to their importance in maintaining the integrity of oil and gas infrastructure. Natural gas pipelines in Qatar are subject to both corrosion and erosion due to the detrimental actions of seawater and sand. The present investigation focuses on evaluation of protective properties of a set of multiphase coating systems in the environment encountered inside of off-shore natural gas pipelines. These coatings are multifunctional coatings systems that promise to provide simultaneous corrosion protection and wear resistance. The coatings ranged in thickness and amount of abrasion-resistant ceramic filler. The sweet oil and natural gas environment in Qatar was simulated by a carbon dioxide (CO2) saturated solutions with 2000 ppm CI & ions at pH 4, at 60°C and atmospheric pressure. Two types of defects were intentionally introduced into the coatings by tribology tester and their response to corrosion environment was studied. The surface topography before and after defects introduction was evaluated by 3-D profilometry. A stereoscope was employed to characterize the morphology of studied coatings. The electrochemical performances and degradations of coated steel panels in tested solution were characterized by electrochemical impedance spectroscopy (EIS) and open circuit potential (OCP) measurements. Different formulations of the organic coating systems had shown a significant change in the impedance response, with immersion time. The data from EIS measurements were fitted into equivalent circuits and the values of their components were calculated and used to understand the interactions between the coating systems and the solution interfaces.
