用于置换输气管道空气的氮气隔离技术

Nitrogen Isolation Technology Used to Displace Air within Pipe for Newly-built Pipeline

    摘要
  • 摘要: 介绍了用于置换输气管道中空气的氮气隔离技术原理和检测方法, 对氮气隔离方法和直接用天然气置换空气的方法进行了比较。通过实例证明了氮气隔离技术的可行性, 提出了采用氮气隔离技术必须具备的条件和应该注意的问题。

     

    Abstract: The technological principle and inspection method of nitrogen isolation technology to displace air with in pipe for newly-built pipeline are introduced and a comparison to the air displacement method with natural gas has been made. The comparison result has shown that this technology is available.especially for the newly-built pipeline. Some requirements necessary and problems to be focused on in applying this technology have been provided.
