The Beijing-Xinjiang Expressway pipeline project traverses deserts and Gobi deserts, facing uninhabited areas with no roads, water, electricity, signal, or rescue services, creating a harsh construction environment. After 75 days, we were fully responsible for the pipeline installation and acceptance. The 330-kilometer water transmission project successfully completed pressure testing on the first attempt, ensuring the smooth completion of the Beijing-Xinjiang Expressway and achieving a major feat in pipeline history. This demonstrates the company's strong construction capabilities in harsh environments.
