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

摘要: 天然氣集輸站場(chǎng)管道缺陷檢測(cè)在天然氣生產(chǎn)管理及安全環(huán)保上扮演著重要角色。近年來(lái),國(guó)際上發(fā)展出以超聲波入射在管壁中形成導(dǎo)波傳播來(lái)對(duì)管道進(jìn)行長(zhǎng)距離全面快速檢測(cè)的方法,既可有效檢測(cè)管道中存在的缺陷,大大降低管道設(shè)備風(fēng)險(xiǎn)指數(shù),又可減少管道檢測(cè)成本。對(duì)超聲導(dǎo)波檢測(cè)技術(shù)在天然氣集輸站場(chǎng)的管道檢測(cè)中遇到的一些情況進(jìn)行了分析總結(jié)。

Abstract: 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.
