高压注水管线弯头剩余强度评价

Evaluation of residual strength of elbow in high pressure water injection pipeline

鉴于高压注水管道刺漏的不确定性,无法精确预计管道穿孔的时限,采取了在常规最小理论壁厚值剩余评价方法基础上,尝试ASME B31G准则进行综合评价。

In view of the uncertainty of puncture and leakage of high-pressure water injection pipeline,it is impossible to accurately predict the time limit of pipeline perforation. Based on the conventional residual evaluation method of minimum theoretical wall thickness,an attempt is made to conduct a comprehensive evaluation according to ASME B31G criterion.
