Pipe　inspection　is　an　important　issue　from　the　perspective　of　power　plant　thermal　equipment　safety.　It　is　difficult　to　inspect　pipe　with　the　conventional　non-destructive　methods,　because　of　a　high　temperature　and　a　limited　accessibility　in　the　region.　The　fundamental　torsional　guided　wave　is　very　effective　for　long　range　crack　of　pipe　inspection,　because　of　its　non-dispersive　characteristics.　In　order　to　generate　non-contact　T(0,　1)　mode,　array　of　fundamental　torsional　mode　electromagnetic　acoustic　transducers(EMATs)　is　designed　and　developed.　Using　the　transducer,　T(0,　1)　mode　is　generated　and　detected　in　the　thick-wall　pipe　with　small　diameter.　By　optimizing　the　element　connections　of　array　of　EMATs,　when　the　elements　are　connected　in　parallel,　the　generated　signal　energy　not　only　can　be　improved,　but　also　other　modes　can　be　inhibited.　Meanwhile,　the　frequency　response　characteristic　is　tested　and　the　artificial　defect　along　the　circumferential　direction　of　the　sample　pipe　is　detected.　The　transducer　can　achieve　identification　and　accurate　location　of　crack　in　the　circumferential　direction　of　the　sample　pipe.　This　proposed　method　provides　a　certain　foundation　for　generation　and　detection　T(0,　1)　mode　and　non-contact　detection　of　cracks　in　the　pipe.　©　2015　Journal　of　Mechanical　Engineering.
