摘　　要：石油石化设备在使用过程中结垢严重会引起效率低下,腐蚀穿孔,不能正常使用,甚至引起安全事故,清洗技术能较好地解决这些问题。以热煤炉、原油换热器为例,介绍了装置的结垢状况,分析了结垢原因以及产生的影响;以东营输油站的热煤炉、原油换热器结垢清洗为例介绍清洗技术的工业应用;详细介绍了清洗的方法、步骤,化学清洗过程中用药量的控制,采取的必要措施,以及清洗后达到的效果;热煤炉通过采用化学清洗取得良好的效果,原油换热器通过高压水清洗取得良好的效果。清洗技术在降低设备腐蚀,提高设备使用效率,保障设备安全运行,延长设备使用寿命上起到了积极的作用。BP artificial neural network algorithm was applied to establish the failure prediction model of corroded pipelines based on BP artificial neural network. With artificial neural network fitting limit state equation, a large amount of limit state function values generated from artificial neural network function mapping relationship are used as analytical data. The random sampling by Monte Carol is applied, and the probability of a wide range of statistic data is analyzed. The reliability index of corroded pipelines is obtained through the probability analysis to get mean value and standard deviation of the state functions of limit, which has solved the reliability analysis problem for corroded pipelines.
