%X This article depicts in detail a kind of guided-waves transducer, used for pipes detection and some relative manufacture techniques of the transducer. Experiments of generating and receiving guided waves on a pipe and a plane with these transducers are carried out. The result indicates that these transducers can effectively generate and receive guided waves.
