最大腐蚀深度预测算法的分析与实现
|
摘要
石化行业涉及各种化工原料和产品,大多使用地面立式金属储罐装载。金属储罐受多种因素影响会不可避免地发生腐蚀,其中储罐底板腐蚀最为严重。基于极值理论的最大腐蚀深度预测符合Gumbel分布,可以有效计算其剩余寿命。实验表明,基于极值理论的最大腐蚀深度预测算法是一种更加科学、可靠的方式。
The petrochemical industry involves a variety of chemical raw materials and products, most of them useground vertical metal tank loading. Metal storage tanks are affected by many factors, and the corrosion of tank bottomplate is the most serious. Based on the extreme value theory, the prediction of the maximum corrosion depth is in line withthe Gumbel distribution, which can effectively calculate the remaining life. The experimental results show that the maxi-mum corrosion depth prediction algorithm based on the extreme value theory is a more scientific and reliable method.
