Take on the role of the primary responsible person! ---------------------------------------------- The past decade has seen significant development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also developed greatly, which has contributed to rapid progress in 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 localization of equipment. Everyone is welcome to share, discuss, and exchange ideas; let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------ Coils were supplied for China’s first major pipeline project using X80-grade steel. The West-East Gas Pipeline Project II was China’s first major pipeline project constructed with X80-grade steel; prior to its construction, there were only around 2,000 kilometers of pipelines built using this grade of steel worldwide, and in China itself there were less than 8 kilometers of test sections. The main line of the West-to-East Gas Pipeline Project Phase II is 4,895 kilometers long; it is entirely constructed using X80 grade pipeline steel with a wall thickness of 18.4 mm and a diameter of 1,219 mm. The maximum pressure capable of being transmitted is 12 MPa. Approximately 2 million tons of coil steel for spiral welded pipes are required for this project. In response to the need for full localization of engineering components and to demonstrate the responsibility of large state-owned enterprises, Ansteel was the first to complete the development work. In December 2007, the first batch of hot-rolled coils and coils for spiral welded pipes were evaluated at the \"New Product Evaluation Meeting for X80 Hot-Rolled Coils and Spiral Submerged Arc Welded Pipes for the West-East Gas Pipeline Project II,\" organized jointly by CNPC and the China Iron and Steel Association. The research, development, and production of thick-gauge, high-grade X80 pipeline steel hot-rolled coils in China have reached international leading levels. From 2008 to 2010, Ansteel supplied approximately 250,000 tons of steel to the West-East Gas Pipeline Project Phase II, serving as one of its main suppliers. Compared with the X70 pipeline steel used in the West-to-East Gas Pipeline Project Phase I, the use of X80 pipeline steel in Phase II can save approximately 420,000 tons of steel and reduce investment by around 4.2 billion yuan. Meanwhile, the designed gas transmission capacity of the West-to-East Gas Pipeline Project Phase II is 30 billion cubic meters per year, which is 2.4 times that of 12 billion cubic meters for Phase I. Li Helin, an academician of the Chinese Academy of Engineering, once said that marked by the West-East Gas Pipeline Project Phase II, China’s pipeline industry has made a leap from following others to taking the lead.
