Yusop, supervisor Mechanical engineering Also available in printed version Crude oil pipelines on the topside offshore platform structure suffers aggressive corrosion attacks from salt sea water. Current painting on the pipe is only last for nine months and there after required costly repainting. The aim of this project is to evaluate the performance of graphene as a nanofiller in zinc-rich epoxy coating to reduce corrosion as compared to virgin paint. Carbon steel pipe (ASTM A106 Gr. B) was obtained from PETRONAS Carigali Sdn. Bhd., Sarawak and used as samples. Zinc-rich epoxy was used as the base paint and mixed with graphene filler at different percentage (0%, 1%, 3% and 5%) to coat the steel samples. Metallurgical analyses were carried out on the samples using Field Emission Scanning Electron Microscopy (FESEM), and Energy Dispersive X-ray Spectroscopy (EDX). An Open Circuit Potential, TAFEL Polarization and Electrochemical Impedance Spectroscopy (EIS) tests were conducted to evaluate the corrosion performance of the coated samples. The results from the experiment show that the virgin zinc-rich epoxy coating on carbon steel pipe can provide corrosion rate at 0.124mmpy for 80?m thickness and reduced to 0.024mmpy for 240?m coating thickness. The higher percentage of graphene filler provides better corrosion resistance. Considering the cost of graphene, coating thickness of 80?m with 5% graphene filler gives six times better protection as compared to virgin zinc-rich epoxy coating at the same thickness of the coating layer shafika UTM 95 p.
