【Major Industrial Equipment in the Chemical Industry】107 – The largest-diameter and heaviest-threaded heat exchanger in China

Thread Content

The past decade has been a period of rapid development for 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! *********************************** In June 2020, 13 threaded heat exchangers manufactured by Lanchi Heavy Equipment were produced and shipped from its headquarters in Lanzhou. The largest shell diameter of these devices is 1.8 meters, while the assembly dimension of their threaded locking rings reaches 2.2 meters; each unit weighs approximately 170 tons. They represent the threaded heat exchangers with the largest diameter and highest weight in China. These devices will be sent to the Green Petrochemical Base in Zhoushan, Zhejiang, for use in the second phase of Zhejiang Petrochemical’s 40 million tons per year integrated refining project
