The pipeline transported about 120 million cubic meters of natural gas a day during the period, according to the company.
With a total length of 1,833 km and a designed annual gas transmission capacity of 60 billion cubic meters, the pipeline was put into service in December 2009.
The pipeline runs from the border of Turkmenistan and Uzbekistan, passes through Uzbekistan and Kazakhstan, and links up with China's West-to-East Gas Pipeline in Horgos, northwest China's Xinjiang Uygur Autonomous Region. It is China's first transnational gas pipeline.
The pipeline has been operating stably and safely for 4,730 days since it was put into service. It benefits over 500 million people in 27 provinces, municipalities, autonomous regions, and the Hong Kong Special Administrative Region.
