China Petroleum Pipeline Bureau successfully opera

On March 23, the maintenance and 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 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 to complete the opening and interconnection of the connecting line between the Sichuan East gas transmission pipeline and Fuling - products, which are widely used in the construction, decoration, logistics and packaging industries. The hot work connection project of pressurized opening is the first time that the Sichuan East gas transmission pipeline is under the high pressure of 67 MPa. As the transmission medium of the construction pipeline is natural gas and 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 that it is 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 progress of hot work, the maintenance and emergency repair company prepares the hot work plan and emergency plan in advance, and arranges full-time HSE personnel to be on duty in the upstream and downstream valve chambers to monitor the pipeline operation status in real time. At the same time, the full-time HSE personnel at the construction site shall monitor the oxygen and natural gas content at any time, and compare them with two combustible gas detectors 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 East Sichuan gas transmission pipeline and the Fuling Wangchang gas transmission pipeline indicates that the East Sichuan 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 the process of industrialization and urbanization, optimizing the energy industrial structure and energy conservation and emission reduction
