Background

西气东输三线工程干线全线分为三段，西段（霍尔果斯－中卫）长2445km，设计压力12 MPa，管径1219mm，设计输气能力300×108m3/a；中段（中卫－枣阳－吉安）长2016km，设计压力12/10MPa，管径1219mm，设计输气能力300/250×108m3/a；东段（吉安－福州）长817km，设计压力10MPa，管径1219mm/1016mm，设计输气能力150×108m3/a。

The West-East Gas Pipeline 3 is being constructed in three sections: East, Middle, and West. The East and West Sections are currently operational, and construction on the Middle Section began in September 2021.

Construction of West-East Gas Pipeline 3 started in October 2012. The pipeline runs from Horgos in western Xinjiang to Fuzhou in Fujian. It crosses Xinjiang, Gansu, Ningxia, Shaanxi, Henan, Hubei, Hunan, Jiangxi, Fujian, and Guangdong provinces.

The overall pipeline is composed of a west, middle, and east section, including eight major branches and some facilities like an LNG terminal, as well as three storage tanks. The pipeline was estimated to cost RMB 142.2 billion (about US$21.55 billion).

The west section was completed in August 2014 and runs the same route as the West-East Gas Pipeline 2. The east section that runs from Ji'an City in Jiangxi Province to Fuzhou City in Fujian Province was completed in December 2016.

The pipeline has a capacity of 30 billion cubic meters per year of natural gas with operating pressure of 10–12 megapascal. The pipeline is supplied from Central Asia–China Gas Pipeline's Line C, supplemented by supplies from the Tarim basin and coalbed methane in Xinjiang.

In September 2021, construction began on the middle section.
