摘要/Abstract

摘要：

针对常压储罐底板检测等日常维护作业中存在的成本高、检测效率低、质量不稳定等问题，开发了一套储罐底板超声相控阵检测系统。该系统采用机械扫查装置辅助实现局部腐蚀损伤的在线高效检测，为保障储罐长周期安全运行提供了技术支撑。提出一种轮式相控阵全聚焦成像算法，提高了检测精度与图像质量。实验结果表明：在12 mm碳钢底板检测中，可稳定检出符合JB/T 10765—2023标准规定的底板下表面深度为20%板厚的人工缺陷；焊缝内表面裂纹检测灵敏度可达5 mm（长）×0.5 mm（深）；缺陷检测图像信噪比相比常规方法增大约10.4 dB。

Abstract:

To address the issues of high cost， low detection efficiency， and inconsistent quality in routine maintenance operations such as inspection of atmospheric storage tank bottom plates， an ultrasonic phased array inspection system was developed for tank bottom plates. A mechanical scanner was employed to facilitate online， efficient detection of localized corrosion damage， providing technical support for ensuring the long-term safe operation of storage tanks. A wheeled phased array TFM imaging algorithm was proposed， and the inspection accuracy and image quality were enhanced. Experimental results show that， in inspecting a 12 mm carbon steel bottom plate， the system may stably detect artificial flaws on the bottom surface with a depth of 20% of the plate thickness， as specified by the JB/T 10765—2023 standard. The detection sensitivity reaches 5 mm（length） × 0.5 mm（depth） for surface-breaking cracks in welds. And the signal-to-noise ratio of defect images is improved by 10.4 dB compared to conventional methods.

Key words: storage tank bottom plate, wheel-mounted phased array, scanning system, total focusing method（TFM） imaging
