| Abstract: | The detection of pipeline crossing section has always been one of the difficult problems in pipeline inspection and detection.In this paper,the Teletest Focus+MK4 guided wave equipment of TWI group in the United Kingdom is used to comprehensively select six crossing sections of a long-distance pipeline in service,such as rivers,gullies,expressways,canals,etc.,with diameters ranging from DN200 to DN350.The practice shows that the single side detection distance of the crossing section pipeline is about 100m,and the inner and outer wall defects of the pipe body can be fully covered;the reliability of guided wave detection can meet the requirements of practical engineering. |
