| 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. |
