The South Trunk Pipeline of Shandong pipeline network is 493 km long, with a design pressure of 10 MPa. The annual gas transmission capacity of the phase 1 is 9.6 billion cubic meters. The pipeline will effectively connect Sinopec's existing pipeline network in Shandong Province, Shandong coastal LNG terminal resources and other gas transmission pipelines in the province, and realize the interconnection of multiple resources and pipelines.

The south Trunk Natural Gas Pipeline project started on March 31st, 2021. Facing challenge of tight construction period and heavy tasks, Shengli Oil Engineering & Construction Co. established a team of professional operators of pipeline automatic welding machines, the operators have been well trained for many times with skills of efficiently operating pipeline automatic welding machine before the beginning of this project. Moreover, pipeline welding machines are well prepared. Both of them are bound to make a good job of the construction in the project.
