| 摘 要： | 通过对长输原油管道直接式加热炉炉管温度分布和力学性能的测试分析,认为加热炉炉管 300℃以下只有腐蚀损伤,温度高于350℃时,炉管主要是蠕变损伤。在此基础上建立了基本方程,提出了加热炉炉管腐蚀损伤后的剩于强度和寿命及炉管蠕变损伤后剩于寿命评估方法。采用上述方法对在用加热炉进行了评估,并对评估结果进行了验证。

| Abstract: | It is concluded from the analysis of temperature distribution and mechanism perfonnance of the tubes of direct fired heaters on long-distance pipelines that the heater tubes are mainly subject to corrosion damage in the temperature below 300 oC and to creep damage in the temperature above 300 oC. On this basis, equations have been established, and techniques for evaluation of the residue strength and life of heater tubes after corrosion damage and creep damage have been proposed. The technique has been applied and results have been verified. |
