根据大连长兴岛一期120万m3原油储罐所处的腐蚀环境及其要求,对其进行了防腐涂装体系设计,介绍了相关材料的主要技术指标和要求,并对GB 50393–2008《钢质石油储罐防腐蚀工程技术规范》规定的导静电涂料的面电阻率为108~1011提出了质疑。以国外相关标准为依据,认为导静电涂料的面电阻率为105~109更符合油品安全要求。
According to the corrosive environment of the 1.2 million m3 crude oil storage tank in Changxing Island of Dalian and its requirements, the anti-corrosion coating system design was introduced. The main technical indexes and requirements of the related materials were introduced. The steel of GB 50393-2008 “Steel Quality Petroleum Tank Anti-corrosion Engineering Specifications ”provisions of the static resistance of the coating surface resistivity of 108 ~ 1011 raised the question. Based on the relevant foreign standards, it is considered that the surface resistivity of the conducting electrostatic coating is more in line with the oil safety requirements from 105 to 109.
