It was learned from China National Offshore Oil Corporation that as of July 8, China's first domestic 12-inch large-diameter hose has transported more than 50 million cubic meters
of natural gas.
The successful operation of this localized hose has solved the problem of Dongfang 1-1 phase I natural gas pipeline transmission in China's first high-temperature and high-pressure gas field, and promoted the efficient development
of the gas field.
The hose is 9.
7 kilometers long and transports high-temperature and high-pressure natural gas of 80 degrees Celsius and a pressure of nearly 10 MPa in the first phase of Dongfang 1-1 to a nearby gas field for processing
.
The original design of Dongfang 1-1 Phase I used 12-inch large-diameter metal composite pipe as a gas pipeline, but this pipeline is laid by large pipelaying ships, which is slow and costly
.
Considering various factors, the Zhanjiang branch of CNOOC decided to use a 12-inch domestic hose instead of a 12-inch composite pipe, saving nearly 100 million yuan
in project investment.
The successful domestic production of this hose has effectively promoted the upgrading
of China's pipe making process.
