Our DN1400 insulated joint delivered to China-Russia East Line (Changling-Yongqing)

Recently, 31 sets of the world's largest diameter DN1400 insulated joint products produced by Xi'an Pump & Valve Plant Co ..Ltd were successfully manufactured and sent to the construction project site of the China-Russia East Line (Changling-Yongqing Section), a national key pipeline construction project.

It is reported that the Sino-Russian East Route Natural Gas Pipeline Project (Changling-Yongqing Section) starts from Changling Sub-transmission Station and ends at Yongqing Liaison compressor Station. It passes through 30 counties (cities and districts) in five provinces (municipalities/autonomous regions), including Jilin, Inner Mongolia, Liaoning, Hebei and Tianjin, with a total length of 1110km.

It is understood that according to the requirements of the State Energy Administration and PetroChina on the localization of DN1400 insulated joints for long-distance pipelines, the Pump and Valve General Factory has carried out the development and engineering application of "new large-diameter insulated joint products". The results have filled the gap in the research on DN1400 insulated joints with the largest diameter in China, improved the product standards of insulated joints and promoted the manufacturing level of the industry. The project won the third prize for scientific and technological progress in China's machinery industry jointly issued by China Machinery Industry Federation and China Mechanical Engineering Society.

At the end of 2019, Xi'an Pump & Valve Plant Co ..Ltd won a large order for the Sino-Russian East Line (Changling-Yongqing Section) after successfully delivering and using the insulated joint of the Sino-Russian East Line (Heihe-Changling). It marks the international leading edge of Xi'an Pump & Valve Plant Co ..Ltd in this field.

In order to ensure the progress of the project, the company's leaders accurately implemented the epidemic prevention and control measures, and strive to resume production on February 19. While focusing on epidemic prevention and production, the company has adopted a number of positive and effective methods and measures. Chen Mengmin, chairman of the company, stressed that it is necessary to win not only the battle of epidemic prevention and control, but also the battle of production and operation. All the staff are not afraid of difficulties, work hard, run out of the acceleration of enterprise development, strive to catch up with various production and operation indicators, and complete the production of large-caliber insulation joint products on schedule.
