Hainan island-ring gas pipeline surpasses 35 billion cubic meters delivered
China's first island-ring natural gas pipeline network in Hainan has cumulatively delivered over 35 billion cubic meters of natural gas, according to the National Pipeline Network Group on September 23. The 899-kilometer network, completed in 2021, serves 14 cities and counties, benefiting over 10 million people. The milestone is equivalent to replacing about 46.6 million tons of coal and reducing CO2 emissions by over 51.2 million tons.

China's Hainan Island Pipeline Network Delivers Over 35 Billion Cubic Meters of Natural Gas
According to a report from Xinhua Finance on September 23, citing the National Pipeline Network Group (国家管网集团), the Hainan Island pipeline network has cumulatively delivered over 35 billion cubic meters of clean natural gas to Hainan Province. This is equivalent to replacing approximately 46.6 million tons of standard coal, reducing dust emissions by about 25.4 million tons and carbon dioxide emissions by about 51.2 million tons, supporting the green development of the Hainan Free Trade Port. The 899-kilometer network, with 14 stations and 42 valve chambers, serves power plants, industrial users, and city gas across 14 cities and counties. The article details the network's phased construction from 1996 to 2021, which formed a full-island loop. To cope with frequent typhoons, the network has deployed an integrated 'sky-ground' monitoring system using satellite remote sensing, drones, and ground sensors for real-time pipeline surveillance and predictive maintenance. All stations have been upgraded with intelligent systems, and six unmanned stations achieved autonomous operation by March 2026, improving fault response speed threefold. Looking ahead to the 15th Five-Year Plan period, the group is actively advancing the construction of a cross-strait pipeline to connect Hainan with the mainland grid, ending the island's isolated energy network.

According to a report from the National Pipeline Network Group (国家管网集团) on September 23, China's first island-ring natural gas pipeline network, the Hainan Pipeline Network, has cumulatively transmitted over 35 billion cubic meters of natural gas. The network, with a total length of 899 kilometers, consists of four main pipelines: Sanya-Dongfang, Dongfang-Yangpu-Haikou, Haikou-Wenchang, and Wenchang-Qionghai-Sanya. It includes 14 process stations and 42 valve chambers, serving 14 cities and counties including Haikou, Sanya, Danzhou, Dongfang, Wenchang, and Qionghai, benefiting over 10 million people. The network primarily supplies gas to power plants, industrial users, and urban gas customers. The cumulative transmission of 35 billion cubic meters of clean natural gas is equivalent to replacing approximately 46.6 million tons of coal, reducing dust emissions by over 25.4 million tons and carbon dioxide emissions by over 51.2 million tons, providing strong support for the green and low-carbon development of the Hainan Free Trade Port.
China's First Island Natural Gas Pipeline Network in Hainan Surpasses 350 Billion Cubic Meters in Cumulative Gas Transmission
According to a report from the National Pipeline Network Group (国家管网集团) on September 23, China's first island-wide natural gas pipeline network, the Hainan Pipeline Network, has cumulatively transmitted over 350 billion cubic meters of natural gas. The network, with a total length of 899 kilometers, consists of four main pipelines: Sanya-Dongfang, Dongfang-Yangpu-Haikou, Haikou-Wenchang, and Wenchang-Qionghai-Sanya. It includes 14 process stations and 42 valve chambers, serving 14 cities and counties including Haikou, Sanya, Danzhou, Dongfang, Wenchang, and Qionghai, benefiting over 10 million people. The gas is primarily supplied to gas-fired power plants, industrial users, and urban gas customers. The cumulative transmission of 350 billion cubic meters of clean natural gas is equivalent to replacing approximately 46.6 million tons of coal, reducing dust emissions by over 25.4 million tons and carbon dioxide emissions by over 51.2 million tons, providing strong support for the green and low-carbon development of the Hainan Free Trade Port and the construction of a clean energy island.

China's First Island-Ring Natural Gas Pipeline Network in Hainan Exceeds 35 Billion Cubic Meters in Cumulative Gas Transmission
According to a report from the National Pipeline Network Group on September 23, China's first island-ring natural gas pipeline network, the Hainan pipeline network, has cumulatively transmitted over 35 billion cubic meters of gas. This milestone provides solid support for the construction of the Hainan Free Trade Port and the development of a clean energy island. The Hainan island-ring pipeline network has a total mileage of 899 kilometers, consisting of four main pipelines: Sanya-Dongfang, Dongfang-Yangpu-Haikou, Haikou-Wenchang, and Wenchang-Qionghai-Sanya. It includes 14 process stations and 42 valve chambers, passing through 14 cities and counties including Haikou, Sanya, Danzhou, Dongfang, Wenchang, and Qionghai, benefiting over 10 million people. The network primarily supplies gas to gas-fired power plants, industrial users, and city gas customers.
China's Hainan Island Pipeline Network Delivers 35 Billion Cubic Meters of Natural Gas
According to a report from Xinhua Finance on September 23, 2024, China's National Pipeline Network Group (国家管网集团) announced that the Hainan Island pipeline network has cumulatively delivered 35 billion cubic meters of clean natural gas to Hainan province. The network spans 899 kilometers with 14 stations and 42 valve chambers, serving power plants, industrial users, and city gas customers across 14 cities and counties including Haikou, Sanya, Wenchang, Lingshui, and Ledong. The pipeline was built in phases from 1996 to 2021, culminating in a full loop around the island. The network has been equipped with a 'sky-ground' integrated monitoring system combining satellite remote sensing, drones, smart cameras, and manual patrols to handle frequent typhoons. All stations have undergone intelligent upgrades, with centralized monitoring systems and six unmanned stations achieving 82% autonomous operation rate. Looking ahead to the 15th Five-Year Plan period, the company is advancing construction of a cross-Qiongzhou Strait pipeline to connect Hainan with the mainland grid, ending the island's isolated energy network status.
