High-frequency guided wave detection of surface cracks in pressure equipment

  • 摘要: 在役承压设备母材内外表面裂纹是一种危害性较大的缺陷,通常采用磁粉、渗透、涡流、射线、常规超声技术对其进行检测,常规检测技术已较为成熟,但也存在一定的局限性。设计并加工了尺寸为1 300 mm×520 mm (长×宽)的裂纹试板,采用高频导波技术对承压设备内外表面模拟裂纹进行检测。结果表明,高频导波技术在承压设备母材内外表面裂纹检测中具有较强的可行性,灵敏度高,检测范围大,检测效率高;在检测距离为600 mm时,可发现深度为0.5 mm的裂纹;针对深度为1 mm的裂纹,可检出的最大距离为593 mm;针对深度为5 mm的裂纹,可检出的最大距离为1 023 mm。
    Abstract: The internal and external surface cracks of the base material of the pressure-bearing equipment in use are a kind of more harmful defect. For this type of defect, magnetic powder, penetration, eddy current, radiation, and conventional ultrasonic detection are usually used. Conventional inspection technology is relatively mature, but it also has certain limitations. In this paper, high-frequency guided wave technology is used to test and research the internal and external surface simulate cracks of pressure-bearing equipment, and a 1 300 mm×520 mm crack test plate is designed and processed. The results show that the high-frequency guided wave detection technology has high feasibility in the internal and external surface cracks of the base metal of the pressure equipment, with high sensitivity, large detection range and high detection efficiency; when the detection distance is 600 mm, the depth of 0.5 mm can be found; For cracks with a depth of 1 mm, the maximum distance that can be detected is 593 mm; for cracks with a depth of 5 mm, the maximum distance that can be detected is 1 023 mm.
