摘要：

In　order　to　overcome　the　conventional　guided　wave　transducer＇s　unsuitability　for　piled　pipe　inspection,　a　non-axisymmetric　end　loading　(NEL)　transducer　is　designed　and　studied　in　this　paper.　Propagation　of　guided　waves　in　a　hollow　cylinder　and　the　circumferential　distribution　of　echoes　from　notches　are　studied　by　using　the　finite　element　(FE)　method　under　different　end　loading　conditions.　The　simulated　results　show　that　when　the　radial　angle　between　the　first　notch　on　a　pipe　and　the　NEL　transducer　is　zero,　the　energy　distribution　from　notch　echoes　is　a　maximum,　even　if　there　are　different　direction　notches　on　the　pipe.　A　specially　designed　clamp　is　developed　to　fix　the　NEL　transducer　to　the　pipe.　Finally,　the　simulated　and　experimental　results　show　that　the　circumferential　and　axial　location　of　the　notch　on　pipe　can　be　located　by　rotating　the　NEL　transducer　during　the　process　of　inspection.
