“…For the pipeline damage detection based on stress wave method, Wang and Chen [17] developed a distributed computer system/network to detect and locate leakage caused by illegal drilling on the pipeline for the purpose of stealing petroleum. Baby et al [18] found that there was inner diameter cracking in pipeline girth welds using creeping waves. Guo and Kundu [19] designed a new sensor and proposed a technique to detect anomalies inside the long pipe wall at a specific depth by selecting an appropriate lamb wave mode.…”

Abstract.To study the feasibility of detecting pipeline multi-cracks damage using piezoceramic transducers, the electromechanical impedance method and the stress wave based active sensing method were used respectively to perform the damage detection of pipeline with multi-cracks. In this research, the lead zirconate titanate (PZT) type transducers were used due to its strong piezoelectric effect and low cost. During the experiments, two artificial cracks on the pipeline specimen were created, ranging from 0 mm to 9 mm, and seven different operating conditions were generated for each artificial crack. In the monitoring test, for the electromechanical impedance method, the damage index based on Root Mean Square Deviation (RMSD) was used, and for the active sensing method, the damage index based on Wavelet Packet Energy Loss (WPEL) was used. In addition, the relationship between the crack depth and RMSD as well as the relationship between the crack depth and location and WPEL were analyzed. The results show that RMSD and WPEL indices increase with the increase of the depth of pipeline cracks. In addition, the WPEL index increases with the appearance of new cracks. Quantitative analysis of pipeline crack damage can be realized by electromechanical impedance method, and localization analysis on the pipeline multi-cracks damage can be achieved by stress wave method based on sensor arrays.

“…Most of the defects begin on the exterior surface of pipe strings and grow as longitudinal cracks [3][4]. But in some key positions, such as girth weld, transverse cracks are the common defects on pipe strings [5][6]. As the crack grows up, it can lead to the failure of pipe string and bring about serious accidents and injuries [7][8].…”

Abstract. Pipe strings (such as drill pipe, tube, pipeline, riser) are critical facilities in oil & gas industry, which are highly susceptible to cracks caused by stress corrosion and fatigue damage. The most common defects are longitudinal and transverse surface cracks on pipe strings in oil & gas industry. Conventional nondestructive testing (NDT) methods are inadequate for these surface cracks on pipe strings. In this paper, a full 360 circumferential current induced by a coaxial excitation coil is present for inspection of longitudinal and transverse surface cracks on pipe strings. The finite element method (FEM) is employed to obtain characteristics signals by analyzing the distorted electromagnetic field above the cracks. The induced circumferential current test system is set up and crack inspection experiments are carried out. The results show that both longitudinal and transverse surface cracks can be detected effectively at one pass scanning on pipe string using the induced circumferential current.

“…Low energy consumption and great cost-effectiveness are features for guided wave-based damage inspection approach [4][5][6][7][8]. The investigations of using Rayleigh surface wave and creeping wave for the detection of surface defects have been studied [9,10]. The use of Rayleigh surface waves or creeping waves; however, has a limitation, that wave amplitude is significantly affected by the surface condition of tested sample.…”
