9 spreads of Xionggu automatic welding machines serve Meng'xi LNG pipeline project. Meng'xi pipeline phase I project has a total length of 413.5km and a pipe diameter of 1016/914mm. Eight new stations, one reconstructed station, 19 valve chambers and one dispatching center are built along the line. The project starts from Tianjin LNG Lingang off load station and ends at Baoding Dingxing off load station. 

It is China's first clean energy “artery” leading directly to Xiong'an new area. The project is listed as the “natural gas interconnection plan” of the National Development and Reform Commission, and is interconnected with the natural gas trunk lines of the national pipeline network such as Shaanxi Beijing second and third line, Sino-Russia eastern line and Beijing Tianjin Hebei branch network, Promote the layout of natural gas infrastructure around the Bohai Sea, solve the "bottleneck" problem restricting the export of LNG natural gas in Tianjin, so that the 6.6 billion m3 / a allocated gas of Tianjin floating LNG terminal can be timely absorbed and released through the Meng'xi pipeline. Xionggu internal welding machine and dual torch external welding machine have participated in construction of the project since May 2021.
