【Major Chemical Equipment】085 – 56-inch ball valve for the China-Russia East Route (Heihe-Changling section) natural gas pipeline project
Thread Content
The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! *********************************** Chengdu Chenggao Valve Co., Ltd. is the only valve manufacturer invited to attend the commissioning ceremony for the \"Development of Energy Cooperation along the China-Russia Eastern Route\" project. According to a announcement released by Chenggao Valves in September 2018, the company won the bid for the 56-inch ball valves and associated electric actuators under Package C1-2 of the gas pipeline project for the China-Russia East Line (Heihe-Changling section), with a total bid amount of 14.75 million yuan.

Construction of the Heihe-Changling section began with the start of the trial phase on June 29, 2015; accelerated construction was launched on December 13, 2017; and the construction tasks were fully completed on October 16, 2019~
The reporter learned from Hebei Iron and Steel Group that the Heihe-Changling section of the China-Russia East Route natural gas pipeline project, which uses this batch of steel, operates in extremely harsh environmental conditions: it is located in a cold temperate continental monsoon climate zone, where temperatures can drop as low as minus 40 degrees Celsius; as a result, strict requirements are placed on the quality of the steel used for the pipe fittings. To cope with low-temperature environments, the impact test temperature specified in the technical requirements for the X80 pipe fitting steel developed by Hebei Iron and Steel Group has been reduced from minus 30 degrees Celsius to minus 45 degrees Celsius. Meanwhile, the impact energy value has increased from a maximum of 70 joules to 135 joules, which is 95 joules higher than the maximum requirement specified in the standards – a level not seen before either domestically or internationally. Furthermore, the diameter of 1422 mm, wall thickness of 57 mm, and minimum service temperature of minus 40 degrees Celsius for this batch of steel are all the highest standards for X80 long-distance pipelines in the global pipeline industry to date. It is understood that during the supply period, HBIS Wugang, which was responsible for production, formed a project task force together with the customer. Based on the specific requirements of the project, they optimized and redesigned the composition of the steel plates as well as the production processes. After several rounds of trial production, they resolved the issue of unstable low-temperature toughness in the steel plates; all performance indicators met or exceeded the customer’s requirements, enabling stable large-scale supply and earning praise from the customer.
