The line extends across north and east China and connects the area around Bohai Sea with Yangtze River Delta. The main pipeline is expected to be put into operation at year-end.

The pipeline will put an end to the coal-dominated energy structure in the areas alongside.

Ji-Ning line is China's first pipeline featuring digital technologies. World advanced technologies are applied in it, including remote sensing technology, geologic information system (GIS), large database, virtual reality technology, web application technology, project management, enterprise resource planning, exploring a new idea and method of in the design and operation management of long-distance pipeline.
