Abstract

Defect quantification and signal processing is the important and fundamental problems in ultrasonic guided wave inspection of pipelines. However, the existing methods struggle to accurately identify low SNR guided wave and quantify defects. To overcome this disadvantage, a quantitative detection of small defect in pipeline using synchronized Lorenz equations and guided wave was proposed. Firstly, a method for the quantification and localization of small defects in pipes was developed using the relationship between reflection coefficients, section loss rates and signal amplitudes. Then, two synchronized Lorenz equations were constructed to identify small defects echo. Theoretical derivation and simulation studies showed that the synchronization error can accurately identify the amplitude and peak arrival time of guided waves under strong noise. Finally, experimental research on guided waves inspection of pipeline showed that it could quantitatively identify a pipe small defect with a section loss rate of 2 %. The errors in the defect size and location identification were less than 5 % and 2 %, respectively. Compared to existing study, this study improved the sensitivity of guided waves inspection for the small defect in pipe and its applicability under noise interference.

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
