Corrosion has a huge economic and environmental impact on virtually all facets of the world’s infrastructure, from highways, bridges, and buildings to oil and gas, chemical processing, and water and wastewater systems. In addition to causing severe environmental damage and threats to public safety, corrosion disrupts operations and requires extensive repair and replacement of failed assets. Localized corrosion of oil and gas pipelines occurs at discrete sites on the surface of the pipeline due to variations in the metallurgical, chemical and physical properties of these sites. This process of corrosion is extremely challenging and difficult to mitigate because it is very dynamic. Localized corrosion of oil and gas pipelines results in enormous economic losses and environmental damage. Although several mitigation techniques have been reported in the literature, a review on the mitigation of localized corrosion is lacking. The main objective of this review is to highlight the various available mitigation approaches of localized corrosion of oil and gas pipelines. Future challenges and research directions related to localized corrosion mainly in oil and gas pipelines are also discussed.

从公路，桥梁和建筑物到石油和天然气，化学加工以及水和废水系统，腐蚀几乎对世界所有基础设施的各个方面都具有巨大的经济和环境影响。除造成严重的环境破坏和对公共安全的威胁外，腐蚀还破坏了运营，并需要进行大量维修和更换故障资产。由于这些位置的冶金，化学和物理特性的变化，油气管道的局部腐蚀发生在管道表面的不连续部位。由于腐蚀过程非常动态，因此腐蚀过程极具挑战性且难以缓解。油气管道的局部腐蚀会导致巨大的经济损失和环境破坏。尽管在文献中已经报道了几种缓解技术，但是缺乏对局部腐蚀缓解的综述。这篇综述的主要目的是强调各种可用的缓解油气管道局部腐蚀的方法。还讨论了与油气管道中局部腐蚀有关的未来挑战和研究方向。
