摘要: 为研究超声相控阵检测技术应用于压力管道对接环缝检测结果的可靠性,选取φ273 mm×13 mm的20号钢管对接环焊焊缝进行研究。焊缝区域分成长度相同的6个区域,其中分别预埋5种缺陷。使用相控阵设备、射线装置和衍射时差法超声检测设备,分别对焊缝进行检测。采用相控阵设备测量各缺陷的相关数据,并与射线检测所得缺陷长度和x轴定位数据进行对比,同时与衍射时差超声检测法所测缺陷自身高度数据进行对比。结果表明,相控阵超声检测技术应用于压力管道焊接缺陷检验可靠性较高;在焊缝返修和缺陷记录方面,相控阵超声检测技术的综合能力优于衍射时差法超声检测技术和射线检测技术。

Abstract: In order to study the reliability of phased array ultrasonic testing for pressure pipe girth welds. In this paper, φ273 mm×13 mm and No. 20th steel pipe are selected and welded by butt ring welding, The weld area is evenly divided into 6 the same length areas and preburied five different defects. Phased array equipment, X⁃ray equipment and diffraction time difference ultrasonic testing equipment were used to detect the weld seam respectively. The relative data of each defect are measured by phased array equipment, and compared with the data of defect length and x⁃axis location obtained by X⁃ray detection, and with the data of defect height measured by Diffraction Time⁃difference Ultrasound Detection. High reliability of PAUT technology for welding Joint inspection of pressure pipeline. For rework and defect recording, PAUT technology is superior to TOFD ultrasonic detection technology and RT technology.

Key words: Pressure pipeline, PAUT, Weld defects, Reliability
