Abstract

Guided-wave testing technology has been used in pipelines for non-destructive testing and structural health monitoring (SHM). This study suggests an electromagnetic acoustic transducer (EMAT(that is bendable and noncontact and is based solely on coils. A planar coil in the shape of a racetrack is used in this transducer design and is fed with pulse current to create a constant magnetic-field, while a second plane meander coil is connected and outfitted with an RF pulse generator to pulse and receive the wave signals reflected from the surface of the pipe as a result of cracks or distortions. The transducer can generate, send, and receive guided waves in ferromagnetic pipes based on the magnetostrictive process without any connection to the tube. The flexible, non-contact, compact shape of the transformer and ease of maintenance properties define this proposed design. It is simple to use with pipes of various diameters. Due to the design's reliance just on size of a coil utilized, it can accommodate a range of diameters. It is further distinguished by being appropriate for smooth surfaces or when most surfaces have exterior coatings for pipes. [ABSTRACT FROM AUTHOR]
