The most popular successful operation of China Pet

On March 23, the maintenance and emergency repair company of CNPC Pipeline Bureau successfully completed the connection between SINOPEC Sichuan East gas transmission pipeline and Fuling Wangchang gas transmission pipeline suitable for most manufacturers

on March 23, the maintenance and emergency repair company of China Petroleum Pipeline Bureau successfully completed the connection between SINOPEC Sichuan East gas transmission pipeline and Fuling Wangchang gas transmission pipeline

the construction site of this project is located in Wangchang Town, Shizhu Tujia Autonomous County, Chongqing. The project requires that the connection line between Sichuan East gas transmission pipeline and Fuling - products are widely used in the construction, decoration, logistics and packaging industries. Otherwise, the test results will be affected. The hot work connection project of pressurized opening is the first time that the Sichuan East gas transmission pipeline has been constructed under the high pressure of 67 MPa. As the transmission medium of the construction pipeline is natural gas, and it is in the peak period of gas consumption in Sichuan and Chongqing, the construction period is tight and the safety risk is high

the maintenance and emergency repair company of the pipeline bureau carried out preliminary excavation, pouring cement buttresses, leveling the site, laying steel plates, supporting Larsen piles, etc. After the safety and environmental protection department of Sinopec Sichuan Chongqing Management Office confirms to be qualified on site, the construction conditions are met and the hot work permit is handled on site. On March 12, the construction party began to enter the site for operation

in order to ensure the smooth operation of hot work, the maintenance and emergency repair company prepares the hot work plan and emergency plan in advance, arranges full-time HSE personnel to be on duty in the upstream and downstream valve chambers, and monitors the pipeline operation status in real time. At the same time, the full-time HSE personnel at the construction site shall monitor the oxygen content and natural gas content at any time, and use two combustible gas detectors for comparison to ensure operation safety. Before assembly and welding, the supervisor shall confirm the cleanliness of the pipeline, and the construction personnel shall operate in strict accordance with the welding 4 composite Portland cement process specification to ensure the construction quality

the successful connection between the Sichuan East gas transmission pipeline and the Fuling Wangchang gas transmission pipeline marks that the Sichuan East gas transmission pipeline has a new strong power, improves the connection of resources, rational allocation and the safety and reliability of gas supply, and is of great significance to accelerating China's industrialization and urbanization, optimizing the energy industrial structure and energy conservation and emission reduction
