通过环境和实验室腐蚀试验方法对油罐底板实际腐蚀状况进行评估, 利用极值统计分析测试最大腐蚀速度, 运用常温和加温方式来体现最严重底板腐蚀状态, 针对具体油罐计算出了实验室腐蚀试验的加速度, 为今后工作提供了可借鉴的经验。 The actual corrosion status of tank floor was evaluated by environmental and laboratory corrosion test methods. The maximum corrosion rate was measured by extreme value statistical analysis, and the most serious corrosion status of floor plate was expressed by room temperature and heating method. Experiments for specific tank The acceleration of chamber corrosion test provides experience for future work.
