摘　　要：针对长输管道工程感应加热弯管母管入厂验收中遇到的母管焊缝热影响区夏比冲击吸收能数值离散性异常、管体屈强比超标及原材料替代等问题进行了分析讨论。基于热模拟方法形成了适用于多种特定母管的个性化感应加热弯管的热煨制工艺,并完成批量工程建设用X80高强度感应加热弯管生产。同时列举了多个力学性能及成分指标存在明显偏离母管工程规范的案例,验证了现行感应加热弯管母管选材规范允许采用热模拟评定方法验收的正确性和可行性。The problems of Charpy impact absorption energy in heat⁃affected zone(HAZ)of base pipe weld,excessive yield ratio of pipe body and substitution of raw materials are analyzed and discussed.Based on the thermal simulation method,a personalized induction heating bending process suitable for a variety of specific pipe is formed,and the production of X80 high strength induction heating bending pipe for batch construction is completed.The correctness and feasibility of the thermal simulation evaluation method in the current material selection specification for induction heating bending pipe are verified by several cases where the mechanical properties and composition indexes are obviously deviated from the engineering specification.
