超声导波在加热炉炉管检验中的应用

针对石油化业中管式加热炉壁厚减薄采用常规测厚方法检测存在的问题,提出了采用超声导波长距离全截面壁厚检测技术。利用该技术对对炼油厂多台管式加热炉炉管危险部位进行检测,举例焦化装置加热炉与常减压装置加热炉的导波检测应用,并通过对检测数据的分析与现场验证,发现了多处安全隐患,并指导用户进行处理,最终得出超声导波技术能有效实现管式加热炉辐射段炉管壁厚检测。

According to the problem of the conventional thickness measurement method for the furnace wall thinning in petrochemical industry, this paper proposed a new NDT named ultrasonic guided to detect the presence of the wall thickness. Utilizing the technique for detection of dangerous parts of the refinery furnace tube on the coker furnace and the furnace of crude oil distillation unit, guided wave inspection were applied for example, and through analysis of test data and field-proven, many potential safety hazard were found, this paper guide the user to process correctly. It concluded that the ultrasonic guided wave technology could effective realization radiation section of the furnace tube wall thickness detection.
