“…Furthermore, Mostafapour et al used analytical modeling to locate leakage in a high pressure pipe, and then validated with experiments [ 13 ]. Current challenges of the AE method include the attenuation of propagating elastic waves in relatively long structures, the requirement of a large number of sensors for covering the entire range of pipeline, the interference of background noise and proper selection of wave velocity due to dispersive characteristics of pipes [ 14 , 15 ].…”

Phononic crystals have the ability to manipulate the propagation of elastic waves in solids by generating unique dispersion characteristics. They can modify the conventional behavior of wave spreading in isotropic materials, known as attenuation, which negatively influences the ability of acoustic emission method to detect active defects in long-range, pipe-like structures. In this study, pipe geometry is reconfigured by adding gradient-index (GRIN) phononic crystal lens to improve the propagation distance of waves released by active defects such as crack growth and leak. The sensing element is designed to form a ring around the pipe circumference to capture the plane wave with the improved amplitude. The GRIN lens is designed by a special gradient-index profile with varying height stubs adhesively bonded to the pipe surface. The performance of GRIN lens for improving the amplitude of localized sources is demonstrated with finite element numerical model using multiphysics software. Experiments are conducted using pencil lead break simulating crack growth, as well as an orifice with pressured pipe simulating leak. The amplitude of the burst-type signal approximately doubles on average, validating the numerical findings. Hence, the axial distance between sensors can be increased proportionally in the passive sensing of defects in pipe-like geometries.

“…Detection technology based on distributed fiber sensors is widely used at present to detect pipeline leaks [9][10][11][12][13][14][15][16][17][18][19][20]. In this method, a fiber is arranged along the pipeline to determine whether the pipeline is leaking and to locate the leaking position by detecting the vibration or temperature change caused by the leak.…”

Natural gas pipeline leaks can lead to serious and dangerous accidents that can cause great losses of life and property. Therefore, detecting natural gas pipeline leaks has always been an important subject. The negative pressure wave (NPW) method is currently the most widely used leakage detection method. Generally, this method uses pressure sensors to detect NPW signals to assess the leak and determine the location of the leakage point. However, the installation of a pressure sensor requires penetrating the pipeline structure, so the sensor intervals are often distant, leading to large signal attenuations and the ineffective detection of small leaks. An NPW method based on fiber Bragg grating (FBG) strain sensors is proposed in this paper which detects NPWs by monitoring the annular strain of the pipeline. Moreover, due to the advantages of nondestructive installation FBG strain sensors can be arranged closer along the distance of the pipeline, the attenuation of the NPW is small and the detection of leaks is improved. This method is tested through experiments and compared with a pressure sensor-based method; the experimental results verify that the proposed method is more effective in detecting natural gas pipeline leaks.

“…Extensive usage of the pipeline and piping system will lead to continuous damage towards the system as the number of accidents has increased significantly due to the increase in the number of ageing pipelines that are still in-service [1]. Continuous operation throughout the day and night of the piping system will be hindered by defects in the system, such as corrosion, weld defects and third-party damage [2]. As a result, consequences such as economic, environmental, and human losses are done due to these defects.…”

Piping systems are important in the oil and gas plant’s operation, but continuous damage is harming the piping system due to extensive usage resulting in the increase of accident cases. API 570 Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems has proposed an in-service piping inspection practice to ensure the in-service piping is functionable by identifying the remaining life of the piping system. However, the in-service piping inspection process is numerous and complicated where certain steps may be skipped, and data collected may lost along the process. The in-service piping inspection framework followed by a work-aid tool is developed in this study based on API 570 to guide the user the piping inspection process along with providing a depository database for document storage. Validation test is conducted by collecting feedback from professional piping engineer using System Usability Scale followed by conducting a case study using secondary data and sample attachment to test the functionality of the work-aid tool. The work-aid tool can guide the piping inspection process and provide a systematic documentation method for corresponding inspection documents. Case study in the industry is recommended to test the usability of the tool in the industry.
