- 摘要:
管道缺陷常规检测技术需剥离管道外防腐层后逐段检测，存在一定局限性。利用超声导波沿管道轴向长距离传播、全壁厚覆盖的特性，基于Comsol软件建立含90°弯管的集输管道模型，分析模型中导波在不同管道位置的能量分布，结合反射系数指标和匹配追踪算法，实现管道缺陷的定量分析，并探究弯管及其后直管段缺陷的检测灵敏度。结果表明，超声导波经过弯管时，在弯管外弧侧出现能量聚集现象，弯管外弧侧缺陷的定位精度最高，相对误差仅为2.61%；反射系数随缺陷周向宽度增加呈线性变化，随径向深度增加呈指数变化；匹配追踪算法能有效分解缺陷前后端的叠加回波信号，当缺陷轴向长度超过20 mm时，误差进入稳定区域。现场验证了3个管架支撑座处的管道腐蚀缺陷，超声导波检测结果相较于实际测量值的误差均在3.5%以内。研究成果可为集输管道完整性管理提供理论依据与工程应用经验。
The conventional detection technology for pipeline defects requires the inspection section by section after stripping the external anti-corrosion layer of the pipeline, which has certain limitations. By taking advantage of the long-distance axial propagation and full wall thickness coverage of ultrasonic guided waves along the pipeline, a gathering line model with a 90° bending pipe was established based on Comsol software. The energy distribution at different pipeline positions in the model was analyzed. Combined with the reflection coefficient index and the matching tracking algorithm, a quantitative analysis of pipeline defects was achieved, and the detection sensitivity of defects in bending pipes and subsequent straight pipe sections was explored. The results show that when the ultrasonic guided wave passes through the bending pipe, an energy accumulation occurs on the outside of the bending pipe. The positioning accuracy of the defect on the outside of the bending pipe is the highest, with a relative error of only 2.61%. The reflection coefficient changes linearly with the increase of the circumferential width of the defect and exponentially with the increase of the radial depth. The matching tracking algorithm can effectively decompose the superimposed echoes at the front and back ends of the defect. When the axial length of the defect exceeds 20 mm, the error enters a stable area. The ultrasonic guided wave detection results of the corrosion defects of three pipe rack support seats were verified on site. Compared with the actual measured values, the error is within 3.5%. The research results can provide a theoretical basis and engineering application experience for the integrity management of gathering lines.
