China and Russia east line natural gas pipeline entry from Heilongjiang Province, through Heilongjiang, Jilin, Inner Mongolia, Liaoning, Hebei, Tianjin, Shandong, Jiangsu, the 8 provinces and municipalities and so on, and stop at Luzhi Liaison Station in the west line of Jiangsu Province. Design throughput is 380×108m3, and design pressure is 12/10MPa.
 
The trunk line of Heihe - Changling starts from Heihe, and stops at Changling transmission station. Set up 6 seats in the process station, and they are t he first station of Heihe (with the function of dividing and pressurizing), Wudalianchi sub transmission pressure station, clear water pressure transmission gas station, Daqing sub transmission station, Zhaoyuan sub transmission pressure station and Changling sub transmission station. Trunk line sets 28 line truncated valve chambers, inside, Class A monitoring valve room has 4 seats, and class B monitoring valve room has 8 seats, and monitoring valve room has 16 seats (with the function of remote control).

The pipe diameter is 1422mm, and the design pressure is 12MPa. In the Heihe-Changling section, large rivers along the main line pass through 7 seats engineering, medium rivers pass through 9 seats engineering.

Welding of natural gas pipeline mainly use efficient cutting gas, mixed gas, acetylene gas and industrial oxygen of Harbin liming company. Carry out the welding of natural gas pipeline, after connecting, using the high efficiency cutting gas to carry out anticorrosion, and then buried down to the ground.
