June 14, 2022 – Nitrogen Purging Project at Dayou Gas Transmission Station & Dongsheng Gas Transmission Station


On June 14, our company meticulously executed the nitrogen purging of the newly constructed D610mm pipeline (total length: 42 km) connecting the Nanchuan Dayou Gas Distribution Station in Chongqing to the Dongsheng Gas Distribution Station—preparing it for commissioning. Equipment debugging was completed at 7:00 a.m., and operations were officially launched on time at 8:10 a.m. After five hours of relentless, coordinated effort, the pipeline successfully passed its first inspection and was declared complete by 1:10 p.m. Throughout the project, the team maintained rigorous standards and worked seamlessly together, delivering flawless execution within the exacted timeline while ensuring exceptional quality—a performance that earned high praise from the client.
