The West–East Gas Pipeline is a set of natural gas pipelines which run from the western part of China to the east.Construction of the third pipeline started in October 2012 and it is to be completed by 2015. The third pipeline will run from Horgos in western Xinjiang to Fuzhou in Fujian.It will cross Xinjiang, Gansu, Ningxia, Shaanxi, Henan, Hubei, Hunan, Jiangxi, Fujian, and Guangdong provinces.

The total length of the third pipeline is 7,378 kilometres (4,584 mi), including 5,220-kilometre (3,240 mi) trunkline and eight branches. In addition, the project includes three gas storages and a LNG plant. It will have a capacity of 30 billion cubic metres (1.1 trillion cubic feet) of natural gas per year with operating pressure of 10–12 megapascals (1,500–1,700 psi). The pipeline will be supplied from Central Asia–China gas pipeline's Line C supplemented by supplies from the Tarim basin and coalbed methane in Xinjiang.

WUZHOU  large-diameter high-pressure full welded ball valve, using 3D finite element analysis, uses the advanced valve design, combined with previously in the oil commissioned Wuzhou plant anatomy of foreign companies of large diameter high-pressure welded ball valve leakage, design a reliable seat sealing structure, the valve can guarantee in the main line the effective operation of 30 years of life. Next, Wuzhou valve will send professional after-sales service engineers, with on-site valve installation and debugging, the perfect completion of this glorious task.
