摘　　要：针对采油树阀门法兰钢圈槽的检测工艺问题,利用相控阵超声检测技术可形成具有不同角度的扇扫扫查方式。在模拟试块上进行反复试验,通过对检测工艺的研究与分析,确定采油树阀门法兰钢圈槽的检测工艺。工艺验证证明,研究的检测工艺可有效避开法兰上螺栓工艺孔对钢圈槽侧壁和底部进行检测,采用斜入射扇扫方式及精确的声束角度设置可以检测到位于在工艺孔下方的钢圈槽底部缺陷,以及不同大小缺陷的回波幅度。回波幅度和扫查中所形成的缺陷面积及实际缺陷大小呈正比关系。In response to the issues encountered during the detection process of the flange steel ring groove of Christmas tree valves,a phased array ultrasonic detection technology-based fan scanning inspection method with varying angles was devised.A series of experiments was conducted on simulated test blocks.Following an in-depth examination of the detection process,the procedure for examining the flange steel ring groove of Christmas tree valves was established.The process validation experiment demonstrates that the detection process studied and analyzed in this article can effectively circumvent the bolt process holes on the flange,thereby enabling the detection of the side walls and bottom of the stel ring groove.By employing the oblique incidence fan scanning method and precise sound beam angle setting,the echo amplitude of defects of varying sizes situated below the process holes can be discerned,and the defect area formed in the scan is directly proportional to the actual defect size.
