The guided ultrasonic waves have become interesting alternatives to classical pulse-echo nondestructive testing in industrial piping systems. These guided waves have the capability to travel for several meters along pipes, bringing back to the emitting transducer information about possible defects. For this reason, researches were conducted in many laboratories of the world for the last decades. In our country such preoccupation is relatively recent. Benefiting from a national research project, our team has also developed original software to solve the dispersion curves of tubes. These dispersion curves provide the travel velocity of the guided waves, which are functions of frequency. In most cases, for a given frequency, there are many propagating waves with specific stress-displacements patterns, which are called guides modes. Using these velocities, the experimentalist can adjust the receiver to detect the selected mode, which can be used to detect defects. The present paper presents the capabilities of the specialized software pack "Tubewave", developed by our team, for homogeneous, isotropic tubes, immersed in air or other light fluids.
