原油储罐高防腐体系的分析及研究

Analysis and Study on the Heavy-duty Anticorrosion of Crude Oil Tanks

根据对本地区原油储罐腐蚀性环境的研究,归纳出储罐内部和外部腐蚀因素。介绍了储罐防腐蚀设计中涂层保护和阴极保护并用所存在的问题,提出利用长链多官能团硅烷偶联剂表面处理技术结合重防腐涂料(无溶剂纳米环氧树脂涂料、负离子吸收型导电涂料等)的解决方案。拟定建立原油储罐全面防腐蚀体系,为沿海储罐防腐蚀工作提供可行性依据和理论参考。

On the basis of the research on the corrosion environment of crude oil tanks in the area, the corrosion factors of the interior and exterior of the tankswere summarized, and the questions about the interaction of coating protection and cathodic protection in the anticorrosion design for crude oil tanks were introduced in the paper. It proposed a new solution which combined surface treatment technology, which used long-chain and multifunctional silane coupling agent, with heavy corrosion protection coatings such as solvent-free nano-modified epoxy resin coating, anion absorbed conductive coating and so on. This corrosion protection system of crude oil tanks provided feasibility foundation and theory reference for the anticorrosion of crude oil tanks in coastal areas.
