Pipelines, the irreplaceable core of energy transmission, are playing a leading role. Energy pipelines, particularly transmission pipelines, are often built of metal and are prone to corrosion by nature. The stifling of energy pipelines is a prominent concern. Corrosion inhibitors are extremely useful, as they are often used to reduce the dissolving behavior of energy pipelines. Because of the simplicity of the process, synthetic chemicals are utilized in corrosion inhibition. In this paper, investigations through potentiodynamic polarization, and electrochemical impedance spectroscopy were used to test new corrosion inhibitors such as P-Tolyl sulfoxide compounds for corrosion on gas pipelines in sea water (EIS).The results indicate that these inhibitors show an protection performance and achieve the corrosion inhibition efficiency values of 82.68%, 79.04% for polarization studies, electrochemical impedance spectroscopy respectively. The surface analysis of gas pipeline was investigated using and energy dispersive X-ray (EDX) methods.
