Detection, Localisation and Assessment of Defects in Pipes Using Guided Wave Techniques: A Review

Abstract

This paper aims to provide an overview of the experimental and simulation works focused on the detection, localisation and assessment of various defects in pipes by applying fast-screening guided ultrasonic wave techniques that have been used in the oil and gas industries over the past 20 years. Major emphasis is placed on limitations, capabilities, defect detection in coated buried pipes under pressure and corrosion monitoring using different commercial guided wave (GW) systems, approaches to simulation techniques such as the finite element method (FEM), wave mode selection, excitation and collection, GW attenuation, signal processing and different types of GW transducers. The effects of defect parameters on reflection coefficients are also discussed in terms of different simulation studies and experimental verifications.

Microwave Nondestructive Testing for Defect Detection in Composites Based on K-Means Clustering Algorithm

“…One of the main difficulties of tackling the problem relating to insulation is the inability to quickly detect and measure the severity of those areas that are suffering from various obscured defects such as corrosion, delamination, and cracks on the structure under insulation [3]. As these faults grow undetected, they can lead to critical system failures with many detrimental effects, including the risk to the safety of site workers [4], environmental disruption and economic effect on maintenance costs and production losses [5]. Therefore, a predictive inspection method evaluating the integrity of the structure is required to prevent these accidents using nondestructive testing (NDT) and to secure the safety and the health of the pipelines.…”

Experimental Study on Dispersion Effects of F (1,1) Wave Mode on Thin Waveguide When Embedded with Fluid

“…Waveguide based sensors have been used for wide range of measuring applications such as temperature, rheology, fluid level, etc., of the surrounding fluid [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Ultrasonic guided waves have been a relevant tool for non-destructive testing (NDT) and structural health monitoring (SHM) technologies due to their wide screening of the acoustic field and their ability to propagate long distances in large structures [ 9 , 10 , 11 , 12 , 13 ]. Ultrasonic guided wave-based waveguide sensors have the potential to resolve some of the major drawbacks of standard temperature (e.g., sensor drift, junction failure, etc.)…”

Weighted Structured Sparse Reconstruction-Based Lamb Wave Imaging Exploiting Multipath Edge Reflections in an Isotropic Plate

“…Lamb waves are ultrasonic guided waves in thin plates and have received great attention from researchers in the field of structural health monitoring (SHM) and nondestructive evaluation (NDE) [ 1 , 2 , 3 ]. Lamb waves are an attractive tool for SHM and NDE because of their ability to achieve large-scale and long-distance detection as well as their sensitivity to several types of damage such as crack, delamination and corrosion [ 4 , 5 , 6 , 7 ]. A typical Lamb wave-based SHM or NDE system usually consists of a sensor array to receive the responses to a specific excitation.…”
