Fault detection in small diameter pipes using ultrasonic guided wave technology
Fault detection in small diameter pipes using ultrasonic guided wave technology
Ultrasonic
guided wave technology is one of the more recent developments in the field of
non-destructive evaluation. In contrast to conventional ultrasonic, this
technology requires exposing only the areas where the transducers will be
placed, hence requiring minimal insulation removal and excavation for buried
pipes. This paper discusses how this technology can be used to detect defects
in pipes under different conditions. Here the experiments were performed on
small diameter pipes (<5 cm diameter); which were bare pipe, buried pipe and
bitumen coated pipe. The results were gathered to see the effectiveness of this
technology in detecting defects.
Experiments were conducted using two dry coupled piezoelectric transducers,
where one of them transmitted guided waves along the pipe and the other
received them. The transducers produced tangential displacement, thereby
generating the fundamental torsional mode T(0,1). In order to assess whether
having multiple transducers has any effect on the resultant waveform, the
receiving transducer was rotated around the circumference of the pipe.

Abstract
Ultrasonic
guided wave technology is one of the more recent developments in the field of
non-destructive evaluation. In contrast to conventional ultrasonic, this
technology requires exposing only the areas where the transducers will be
placed, hence requiring minimal insulation removal and excavation for buried
pipes. This paper discusses how this technology can be used to detect defects
in pipes under different conditions. Here the experiments were performed on
small diameter pipes (<5 cm diameter); which were bare pipe, buried pipe and
bitumen coated pipe. The results were gathered to see the effectiveness of this
technology in detecting defects.
Experiments were conducted using two dry coupled piezoelectric transducers,
where one of them transmitted guided waves along the pipe and the other
received them. The transducers produced tangential displacement, thereby
generating the fundamental torsional mode T(0,1). In order to assess whether
having multiple transducers has any effect on the resultant waveform, the
receiving transducer was rotated around the circumference of the pipe.
