The transportation of oil and gas through pipelines is an integral aspect of the global energy
infrastructure. It is crucial to ensure the safety and integrity of these pipelines, and one way …

The use of guided waves is now widespread in industrial NDT for locating metal loss in
pipelines, that manifests as pitting, corrosion and general wall thinning. In this paper, a …

The present study explores mode conversion of shear horizontal (SH) guided wave when it
im**es on smooth defects in plates. The fundamental (SH0) and the first higher (SH1) …

The fundamental circumferential shear horizontal (CSH0) wave is of practical importance in
monitoring corrosion defects in large-diameter pipes due to its virtually non-dispersive …

Utilizing the SMART Layer technology as a basis, a real-time active pipeline integrity
detection (RAPID) system is developed for built-in in situ assessment of the health of new …

The circumferential 0-mode shear horizontal (CSH0) guided waves have great advantages
for the detection of cracks in pipelines due to the small attenuation of acoustic signals …

In this paper, SH (shear horizontal) guided waves propagating in the circumferential
direction of pipeline are modeled in 3 dimensions, with the aim for axial cracking detection …

We propose a new method for wall-thinning inspection based on mode conversion of shear
horizontal (SH) guided waves, which is represented as group velocity change. Group …

The electromagnetic ultrasound detection technology provides an efficient method to inspect
the structural health status. For the pipeline structure, the guided ultrasonic wave …

This study develops an optical fiber–guided laser ultrasonic system and baseline-free
damage detection method that enables structural health monitoring of pipelines employed …
