摘要:
为了准确评估腐蚀损伤后的 API J55级HFW套管剩余强度，以在石油钻机中使用了70 000 h的套管为研究对象，通过加工不同损伤程度的人工缺陷对管道进行压力试验，研究了套管腐蚀损伤后管道内的最大允许压力评估标准，并进行了有限元数值模拟。采用ASME B31G标准、修订后的ASME B31G标准、CHoi’s 结论的三种表达式估算了腐蚀损伤后管道的剩余强度值，并与有限元分析结果进行了比较。结果表明，腐蚀损伤缺陷的深度小于管体的50%时，不会影响其结构的完整性；有限元模拟计算结果与试验结果吻合；利用有限元方法进行腐蚀损伤预测时很大程度上取决于其参考应力值。
Abstract:
In order to accurately evaluate the residual strength of API J55 HFW casing after corrosion damage, the casing used in oil drilling rig for 70 000 h was taken as the research object, and the pipeline pressure test was carried out by processing artificial defects with different damages. The maximum allowable pressure evaluation standard in the pipeline after corrosion damage was studied, and the finite element numerical simulation was carried out. The residual strength of the pipeline after corrosion damage is estimated by three formulas of ASME B31G standard, revised ASME B31G standard and CHoi’s conclusion, and compared with the results of finite element analysis. The results show that when the depth of corrosion damage defect is less than 50% of the pipe body, the structural integrity will not be affected. The results of finite element analysis simulation are in good agreement with the experimental results. When using the finite element method to predict the corrosion damage, it largely depends on the reference stress.
