Improving the Coating Properties of Petroleum Product Pipelines Using Nanomaterials

Abstract

In this research, coating mixtures of several percentages were prepared using aluminium oxide or alumina powder AL₂O₃. Pieces of petroleum derivatives pipes were selected and formed with equal dimensions (2x2x2) mm with several (5) pieces. The mixtures were prepared using the liquid mixing method and ultrasonic technology to stimulate the composites (coatings) from a percentage of (5%) to a percentage of (20%) of (AL₂O₃). Then they were mixed and added to the paint used in coating the pipes by immersion. The Tafel method was used to calculate the corrosion rate (electrochemical method) and the soil immersion method, and the results were compared between the two methods. The results showed a significant improvement for the samples reinforced with a percentage of (10%), the lowest corrosion rate, compared to the pure model and the coated model free of additives and the rest of the percentages.
