超声导波技术在天然气集输站场管道缺陷检测中的干扰因素分析

天然气集输站场管道缺陷检测在天然气生产管理及安全环保上扮演着重要角色。近年来,国际上发展出以超声波入射在管壁中形成导波传播来对管道进行长距离全面快速检测的方法,既可有效检测管道中存在的缺陷,大大降低管道设备风险指数,又可减少管道检测成本。对超声导波检测技术在天然气集输站场的管道检测中遇到的一些情况进行了分析总结。

Analysis on Interfering Elements in Detection of Pipeline Defects at Natural Gas Gathering & Transferring Station with Ultrasonic Guided-wave Technology

Detection of pipeline defects at the natural gas gathering ＆ transferring station plays an important role in management of natural gas production and safety ＆ environment protection. In recent years, a new detection method for this purpose has been developed in the world, i.e., getting ultrasonic wave incoming the pipe wall to form guided-wave so as to realize long distance, overall and quick detection of the pipeline. This detection process features effective defect inspection, significant reduction of risk index of the pipeline equipment, and cutting down costs of pipeline detection itself. All that involved in the paper are analysis and summary of some operation situations of the said pipeline detection with the ultrasonic guided wave process.
