摘要
加氢裂化工艺管道中,使用的不锈钢材质为TP347,而这种不锈钢在高温高压及应力作用下易发生晶间腐蚀和氢致开裂.为了及时发现这类问题,文章对现有的超声导波、声发射、分布式光纤测温等管道监测技术进行了研究,探讨了红外热成像监测技术的可行性.并现场验证红外热成像监测技术的可靠性,为管道故障的自动诊断和预测提供重要支持.
Abstract
The stainless steel material used in the hydrocracking process pipeline is TP347,which is prone to intergranular corrosion and hydrogen induced cracking under high temperature,pressure and stress.In order to timely detect such problems,this article conducts research on existing pipeline monitoring technologies such as ultrasonic guided waves,acoustic emission,and distributed fiber optic temperature measurement,and explores the feasibility of infrared thermal imaging monitoring technology.And on-site verification of the reliability of infrared thermal imaging monitoring technology provides important support for automatic diagnosis and prediction of pipeline faults.
