| 摘 要： | 基于可靠性理论,提出了一种预测管道腐蚀剩余寿命的新方法,即管道腐蚀可靠性寿命预测方法。该方法包括建立腐蚀管道的失效状态函数、腐蚀速率等变量的概率分布模型、管道失效概率和可靠度随时间的变化规律;然后根据管道所处地区级别和风险等级给定目标可靠度,确定管道的腐蚀剩余寿命。运用此方法预测了新疆采油一厂红浅注汽管道的腐蚀剩余寿命,为该管道腐蚀检测周期的确定提供了科学依据。

| Abstract: | Based on the reliability theory,presented a new method for the remaining life prediction of corroded pipeline.The method includes establishing the limited state function of corroded pipeline,the probability distribution models of variables such as corrosion velocity and the failure probability or reliability verse the service time of corroded pipeline.The remaining lifespan of corroded pipeline can be calculated,as long as the acceptable failure probability or target reliability is determined according to the environmental conditions and risks for the pipeline.The new method has been utilized successfully in the injecting pipeline of Xinjiang oilfield,and the inspection interval of this pipeline can be decided as a result of the remaining life prediction. |
