The West-to-East Natural Gas Pipeline crossed the Yellow River, the
second largest river system in China, through a tunnel Tuesday.
It
marks a major breakthrough in the construction of the project, one
of the four landmark projects in western China.
The 518-meter-long tunnel was laid 20 meters beneath the bed of
Yellow River. It is the first gas pipeline tunnel spanning the
Yellow River.
The success of the pipe laying provided experience for China
enlarge-bore pipelines across large rivers and laid a solid
foundation for gas transmission scheduled in the fourth quarter of
this year, said a project official.
The pipeline's construction, which will take about six years to
complete, began in 2001. In the first stage of the project, the
4,200-km-long pipeline will wind its way through eight autonomous
regions and provinces before entering Shanghai.
It
is expected to transfer over 12 billion cubic meters of natural gas
annually for industrial and domestic use to Shanghai and other
Yangtze River Delta areas from gas fields of the Tarim Basin in
Xinjiang, home to one of China's largest oil and natural gas
reserves with more than 200 billion cubic meters of proven natural
gas reserves.
