油气管道AUT检测技术应用现状及存在问题

Current conditions and existing problems in application of AUT in oil/gas pipelines

  • 摘要: 全自动超声波检测(Automated Ultrasonic Testing,AUT)已在国内油气管道应用多年,国内逐步开展了设备及部件的国产化工作,并制订了相应的技术标准。通过对AUT检测技术在检测人员资质认证及培训、设备与校准试块应用以及技术标准等方面的应用现状进行分析,指出在实际使用过程中面临的诸多问题:在检测人员资质认证及培训方面,培训教材缺失、受训人员技术门槛偏低、高校专业培训不到位等;在设备发展方面,进口设备后续维修保养费用高,国产AUT设备质量、性能等参数尚需现场应用检验;在试块加工与验收方面,不能对试块的实际加工精度做出最终判定,业主的批准认可实际应用意义不大等。针对上述问题,提出了相应的改进措施。

     

    Abstract: Automated ultrasonic testing (AUT) technique has been applied for many years for oil/gas pipelines in China. In this aspect, gradual efforts are made in localization of relevant equipment and elements, and relevant technical standards are stipulated. Applications of AUT technique are facing many challenges in qualification and training of relevant operators, deployment of equipment and calibration test specimens, and availability of relevant technical standards. For example, qualification certification and training for relevant operators suffer from insufficiency of training materials, low technical levels of trainees and insufficient training programs in universities or colleges. As far as equipment is concerned, imported facilities may accompany with astronomical costs for operation and maintenance, while domestic AUT devices require on-site calibration in quality, performance and other parameters. Fabrication and acceptance of blocks may involve missing of ultimate judgment on actual processing accuracy and less significance of clients' authorization in application. Finally, necessary measures for improvements of above problems are proposed.
