The phase I of Mengxi SNG pipeline project includes three pipelines, one trunk line and two branches, passing through Tianjin city and nine counties in Northern China.
The pipeline is 366.51km long crossing large and medium-sized rivers in 35 locations, railways in 9 locations and highways in 51. The pressure of the pipeline is 10MPa, pipe material is L485M.
Among them, Langfang Branch line starts from Bazhou off load station, dia. 914mm, 10MPa design pressure and 28.499km in length. A new station (Yongqing off load station) and two monitoring valve chambers are set. Xionggu Pipeline Automatic Machines complete welding of 2010 joints till the middle of December 2021. Video monitoring and digital management (acquisition and upload of pipe joint temperature and welding data) are adopted to effectively improve the welding quality and efficiency.
