November 20, 2023: Luzwei Pipeline Gas Shutdown for Connection and Nitrogen Purging Project to Resume Production

On November 20, 2023, our company received an urgent notification from Chengdu Natural Gas Chemical Plant, instructing us to arrive at the Erlongkou Pigging Station in Luzhou within 24 hours (by 6:00 PM on November 21) to carry out gas shutdown and connection work on the Luwei pipeline, followed by nitrogen purging to resume production. Promptly responding to the call, the Nitrogen Business Center mobilized immediately—completing the on-site assembly of the liquid nitrogen pump truck and assembling a highly skilled team by noon that same day. Despite facing the dual challenges of significant nighttime temperature drops and confined working spaces, the team proactively implemented preventive measures against cold weather, set up safety alerts, and installed an efficient lighting system. By 8:45 PM on November 21, they precisely kicked off the operation, working tirelessly for 12 consecutive hours until the task was successfully completed at 9:05 AM the next morning. Throughout the entire process, not a single equipment malfunction or safety incident occurred, demonstrating exceptional efficiency in restoring the energy pipeline to full operation—and further solidifying Host's unwavering commitment to delivering top-tier emergency response capabilities, always putting "customer first."
