China National Petroleum and Natural Gas Pipe Network Group Co., Ltd. Monday (June 26) news, 9.45 MPa full -size non -metallic pipeline pure hydrogen blasting test was recently broken control in Hami, Xinjiang HamiThe test site was successfully implemented.This marks the successful completion of China's first high -pressure multi -pipe hydrogen transportation pipeline intermediate process, which provides technical support for China to achieve large -scale and low -cost long -distance long -distance hydrogen transportation in the future.
According to Qiu Yanjuan, a technical expert of China State Pipeline Group Western Pipeline Company, according to the Science and Technology Daily (27th), the test is divided into two stages: the hydrogen charging test and the pure hydrogen blasting test.Three non -metal pipelines and low -steel metal pipelines.The hydrogen charging test is used to simulate the actual transportation environment of the pipeline, maintaining a pressure of 6.3 MPa. After 30 days of testing, the hydrogen compatibility, obstruction and sealing of the pipeline equipment are verified;To 9.45 MPa, implement a full -size pure hydrogen blasting, and further verify the pressure performance and burning form of non -metallic pipelines under the conditions of pure hydrogen pressure.
Qiu Yanjuan introduced that the pipeline size and test pressure involved in this experiment exceeded the main operation indicators of the construction of pure hydrogen pipes in China; it was also the first time that China conducted high -pressure pure hydrogen blasting tests on non -metal pipes to operate the pipeline operation safety.Management comprehensive data analysis provides more comprehensive data support.
Yang Ming, director of the Technology Information Service Center of China National Pipe Network Group Western Pipeline Company, said that it will accelerate the advancement of the cutting -edge technologies such as hydrogen and carbon dioxide storage and transportation, and promote the natural gas pipes' transmission business and the whole country.The integration and development of the new energy business helps the construction of the entire chain industry of hydrogen energy and storage.
