Corrosion Inhibitor of API Pipeline Steels: A Review
摘要
Crude oil and natural gas are essential hydrocarbon resources extensively utilized in various energy sectors worldwide. The transportation of these resources from production sites to refineries relies heavily on pipelines, which must meet stringent standards for strength, durability, and corrosion resistance. High-strength low-alloy (HSLA) steels are the preferred materials for oil and gas pipelines due to their superior mechanical properties, weldability, and resistance to cracking and corrosion. The American Petroleum Institute (API) standards, widely recognized globally, categorize pipeline materials into PSL 1 and PSL 2, with grades ranging from A25 to X120. Maintaining the integrity of API pipelines is crucial to ensuring the safe and efficient transportation of oil and gas. However, corrosion, a major threat, can lead to leaks, environmental damage, and safety risks. One effective method for preventing corrosion in metals and alloys is the use of inhibitors. This review offers a succinct synopsis of the many kinds of corrosion inhibitors. This paper reviews the effectiveness of various corrosion inhibitors, including natural and synthetic compounds, in protecting API pipeline steels in harsh environments. This review explains how different green inhibitors, organic and inorganic inhibitors, polymer inhibitors, and some of the other inhibitors that have been deployed thus far function in protecting the API pipeline. Moreover, this article can be significant for advancing knowledge and guiding industry practices. By synthesizing existing research, this review provides valuable insights into the strengths and limitations of various inhibitors, aiding in informed decision-making. Highlighting eco-friendly inhibitors promotes environmental sustainability, while comparing cost-effectiveness supports economic efficiency. Additionally, this review enhances safety by identifying the most effective corrosion control methods, fosters innovation by showcasing emerging trends, and offers a holistic perspective on corrosion inhibition. This work is indispensable for researchers, engineers, and industry professionals striving for optimal pipeline protection.
