The LanzhouâÂÂZhengzhouâÂÂChangsha product oil pipeline is a pipeline carrying diesel and other oil products from the northwest to the central regions of China. The pipeline starts in Lanzhou in Gansu, and runs through Zhengzhou in Henan to Changsha in Hunan. In Zhengzhou, it is linked with JinzhouâÂÂZhengzhou product pipeline running from Jinzhou in Liaoning to Zhengzhou.
The pipeline project was approved in 2007. The long LanzhouâÂÂZhengzhou segment started operating on 30 March 2009. The ZhengzhouâÂÂChangsha segment is expected to be completed by the end of June 2010. The pipeline has an annual transportation capacity of 15 million tonnes. It is operated by PetroChina.
On 30 December 2009, due to the rupturing of a segment of the pipeline, there was an oil spill in China's Yellow River. Approximately of diesel oil flowed down the Wei and Chishui Rivers before finally reaching the Yellow River on 4 January 2010.
