摘要
对已服役近10万小时的烷基苯加热炉炉管材料进行了试验研究,并对炉管腐蚀产物进行电子探针分析,探讨了加热炉炉管的腐蚀机理.采用FTA技术,对加热炉炉管进行故障树分析,找出影响炉管失效的主要因素,探讨了加热炉炉管的失效模式,提出了失效模式相关的寿命预测数学模型,并对加热炉炉管进行了寿命预测.
An experimental research on the Alkylbenzene heater tubes material which has been operated for about 100 thousand hours is carried out. In addition, the corrosion product of heater tube has been examined by using an electronic probe and probe into the corrosion Mechanism of heater tubes. Based on the fault tree analysis on the heater tubes by using the FTA technology, the paper finds the main factors affecting the failure of the heater tubes, discusses the failure model of the heater tubes, put forward the mathematical mode of life prediction and failure model of the heater tubes.
