Around the pipeline underground, the environment of soil was very complicated, and the pipe shall be easy to be corroded and destroyed, so the reasonable use of outside antisepsis technology can decrease the accident and prolong the lifetime of pipeline. The necessity was explained and the principle of choosing the technology was introduced.
