摘要
燃气管道运营过程中,会受很多因素影响,使其失效,发生泄漏、造成事故,其中最常见的问题就是管体自身的腐蚀老化。文中提出用瞬变电磁法(TEM)检测埋地燃气管道,主要介绍了瞬变电磁法检测在役燃气管道的原理,并结合工程实例对燃气管道进行检测,以验证此方法的可行性。结果表明:利用瞬变电磁法检测埋地燃气管道腐蚀具有有效性和实用性,应进一步研究以提高检测精度与效率,为保障燃气管道安全运营提供新的方法。
Many factors lead to the invalidation in the process of operation which might result in leaks or causing an acci-dent,one of the most common problems is the corrosion and ageing of the pipeline itself. Using transient electromagnetic method （ TEM） to detect the buried gas pipeline was presented. The paper mainly introduced the principle of the TEM to detect the gas pipeline in service and combined with engineering example of gas pipeline detecting that verifies the feasibility of this method. Results show that using the TEM to detect the corrosion of buried gas pipeline has certain validity and practicability,which needs further research to improve the accuracy and efficiency,and can provide a new method to ensure the safe operation of gas pipeline.
