摘要
论述了时间因素使管道金属力学性能发生变化的理由 ,并就管道金属的力学性能、金相组织等与管道使用时间的关系进行了研究 ,对确定石油。
It states that time can cause the metal mechanic properties change of pipeline.After researched the relationship between pipeline service circle and mechanic properties and microstructure of pipeline metal,the relationship is found which plays the practical direction roles in pipeline design and its service circle.
