The Dongdong crude oil pipeline project has a total length of 373 kilometers and 104 directional drills across the entire line.
The Zihe directional drill contracted by the Shijian Company is the longest in the construction of the crossing project, and it is also one of the most critical lines in the entire project.
The length of the pipeline is 1871 meters and the diameter of the pipeline is 762 mm
