9. Harmless treatment of pipeline
Oil and gas pipelines will be damaged by natural environment and human factors during operation, resulting in pipe body defects or leakage accidents. Non-stop pipeline repair is an effective way to extend its service life and reduce the operating cost of pipeline companies. For old oil and gas pipelines that cannot be dismantled and recycled, nitrogen sweeping, steam purging and grouting should be used for harmless treatment to reduce hidden dangers caused by residual oil and gas in the pipeline.
