摘　　要：目前我国化工工业装置中转化炉炉管大多采用HP40材料,这种材料在高温服役过程中,经过长时间的高温蠕变后退化并产生损伤,损伤会逐步发展称为裂纹,最终导致炉管破裂。国内外的相关学者对转化炉炉管的高温蠕变损伤寿命评估进行了相关的研究,并逐步形成了Larson-Miller参数法,但这一方法缺少对工况载荷不确定性的考虑。文章参考前人的研究方法,结合蠕变损伤计算方法对多工况情况下的转化炉炉管剩余寿命进行分析评估。At present,HP40 material is widely used for reformer tubes in chemical industrial plants in China.In the process of high-temperature service,this material degrades and damages after a long time of high-temperature creep.The damage will gradually develop into a crack,which eventually leads to the rupture of the furnace tube.Relevant scholars at home and abroad have carried out relevant research on the high-temperature creep damage life assessment of reformer tubes,and gradually formed the Larson Miller parameter method.However,this method lacks consideration of the uncertainty of working load.This paper refers to the previous research methods,combined with the creep damage calculation method.Finally,the analysis and evaluation of the remaining life of reformer tubes under multiple working conditions are completed.
