An experimental study to evaluate shapes and sizes of defect under thick coating by
microwaves NDT is demonstrated. Specially fabricated thick fire protect coated steel panels …

We report an efficient nondestructive evaluation (NDE) method to measure the pipe wall
thinning (PWT) remotely using microwaves. A microwave vector network analyzer (VNA) and …

This paper addresses the interpolation issue of current spectral estimation methods in
microwave-based nondestructive testing and evaluation. We developed a spatial-frequency …

This study demonstrates that the reflection of microwave propagating inside a pipe enables
one to nondestructively detect and locate wall thinnings appearing inside the pipe. A signal …

This study investigates the potential of microwave technique for online monitoring and
evaluation of biofilms in the pipelines. A microwave vector network analyser and an in …

Metal pipes are used widely in many industries, including oil and gas transportation,
chemical industry and various kinds of power plants. Pipe wall thinning (PWT) is one of the …

High frequency electromagnetic guided waves are used to detect axial narrow slit or crack in
bend-section of the U-shape pipe. In the previous studies performed by the authors …

Research using microwaves (MWs) to detect pipe wall thinning (PWT) distinguishes the
presence of wall thinning, but does not accurately locate the discontinuities. Ultrasonic …

Rapid and reliable non-destructive inspections of piping systems play an important role in
the maintenance of large structures such as power and chemical plants. Whereas several …

This research investigates the application of microwave nondestructive testing (NDT) to oil
and gas pipe wall reductions (PWR) in manufacturing that are less than full-circumferential …
