摘要
介绍TP304H炉管的高温失效原理,并将其与多种耐热钢进行性能对比。结合裂解炉对流盘管中蒸汽过热炉管的使用工况特点,提出材料选择的方法和原则,并得出P91和304H两种材质耐热钢作为裂解炉蒸汽过热炉管材料的具体使用工况。
This paper introduces the failure mechanism of TP304H pipe,and compares its high temperature performance with those of several typical heat-resistant steel.Combined with the working condition characteristics of high temperature steam pipes in convection coil of cracking furnace,the material selection method and principle are proposed.The specific working conditions of P91 replacing 304H are provided.
