Application of Radiographic Detection in Soldered Joint of Buried Polyethylene Pipes for Gas

  • 摘要: 聚乙烯材料衰减系数比金属材料小,理论上可以用射线检测方法对其进行检测。通过试验,选择合适的曝光脉冲数和焦距,对含3种人工缺陷的聚乙烯管道焊接接头进行射线检测,发现对于体积型缺陷的检出率高,而对于面积型缺陷较难检出,说明射线检测适用于检测聚乙烯管道焊接接头中的体积型缺陷。
    Abstract: The attenuation coefficient of polyethylene material is smaller than that of metal material and theoretically it is possible to use a ray detection method. Through the experiment, in which the appropriate number of exposure pulses and focal lengths were selected, three kinds of artificial defects in soldered joint of buried polyethylene pipes were tested by radiation and it was found that the detection rate for volume type defects was high, whereas it was difficult to detect the area type defects. It is shown that ray detection is applicable while detecting volume defects in soldered joint of polyethylene pipes.
