摘要 文章针对某采气厂加热炉管,在进行全面检测的基础上对其腐蚀机理进行了分析,对腐蚀缺陷剩余强度进行了计算,采用有限元、优化设计方法对炉管的剩余寿命进行了预测,最后给出了炉管的综合评价。 The corrosion mechanism was ana- lyzed based on the overall testing and inspection on the heater tube,the residual intensity of cor- rosion defection was calculated,and the residual life—span of the heater tube was predicted by the method of finite element and optimum de- sign.Finally,the synthetic evaluation of the heater tube was provided.
