Detection and Identification of Dents in Pipelines using Guided Waves
Publication: Publication Date: 1 January 2016Testing Method: ,
Dents are one of the primary failure modes in
pipelines, and dent detection is a critical technology
to ensuring pipeline safety. An experimental
study for detection and identification of
dents in pipes using ultrasonic guided waves was
carried out. For revealing the relationship between
the characteristics of reflected guided waves and
the geometric features of dents, the dented region
was represented by a series of circumferential
cross-sections and a quantitative parameter; the
so-called deformation rate was defined to evaluate
the effect of the extent of the dent on the reflection.
Both single- and double-sided dents were
mechanically simulated in hollow aluminum pipes
and then experimentally tested by exciting and
receiving the longitudinal L(0,2) mode. The results
show that the L(0,2) reflection coefficients from
both types of dents increase monotonically with
their respective deformation rates at all selected
frequencies. The radial displacement of the L(0,2)
mode may be a primary factor influencing the
sensitivity of the dent detection. It is shown that
the L(0,2) reflection coefficients decrease markedly
at lower frequencies while decrease slightly at
relatively high frequencies. Furthermore, the
tendency of the curve of reflection coefficient with
frequency is similar to that the radial displacement
of the L(0,2) mode versus frequency. These characteristics
indicate that the wideband L(0,2) mode
provides a viable technique for detection and identification
of dents in pipelines
