| Abstract: | 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. |
