沿海地区成品油储罐防腐技术的应用实践

Application Practice of Anti-Corrosion Technology for Oil Product Storage Tanks in Coastal Areas

针对沿海地区成品油储罐受空气环境温度、湿度及氯离子浓度、紫外线强度等因素影响,易发生储罐腐蚀,轻则导致油品跑冒滴漏,重则导致生产安全事故及环境污染事件的状况,在简要介绍了国内钢制储罐外壁腐蚀机理研究现状的基础上,分析了沿海地区环境情况对钢材腐蚀的影响,介绍了钢制储罐常用防腐涂料的选用原则和常用涂料性能,提出了施工工序和技术指标要求以及质量控制要点,为同类工程施工提供了参考。

In view of the situation that the oil product tanks in coastal areas are prone to corrosion due to factors such as ambient air temperature,humidity,chloride ion concentration,and ultraviolet intensity,which may lead to oil leakage,or even production safety accidents and environmental pollution events,based on a brief introduction of the current research situation of the corrosion mechanism of the outer wall of steel tanks in China,the impact of the environmental conditions in coastal areas on steel corrosion is analyzed.The selection principle and performance of common anticorrosive coatings for steel tanks are introduced,and the construction process,technical index requirements and quality control points are put forward,which can provide a reference for the construction of similar projects.Key words:coastal areas,oil product,steel tanks,anti-corrosion,technology,application,practice.4 Promotion and Application of Explosion=Proof Hanging Basket in Oil Tank Construction.Yan Chengxin.Abstract:The structure,application and existing shortcomings of the common hanging basket and scaffold used in the construction of oil tanks in the oil depot are pointed out,the concept,characteristics,working principle,technical parameters,installation,application and precautions of the explosion-proof hanging basket are introduced,and the construction benefits of the explosion-proof hanging basket and the scaffold are compared from the aspects of construction period and engineering costs.Explosion-proof hanging basket is used in oil tank construction,which is low-cost,labor-saving and safe,which is recommended to be popularized.
