Comply with the Work Safety Law! Take on the role of the primary responsible person! ---------------------------------------------- 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. China’s chemical equipment sector has also seen significant progress, which has contributed to the swift development of the petrochemical industry. 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, discuss, and exchange ideas – let’s cheer for Made in China and support the development of chemical equipment! ------------------------------------------------------ In 2018, LANSHI Heavy Equipment Corporation manufactured 4 polymer-grade ethylene spheres with a capacity of 3,000 m3 each for Ningxia Baofeng Energy Group’s project aimed at producing 600,000 tons of olefins per year. This spherical tank is the largest low-temperature steel spherical tank with a thick wall in China, manufactured by Chongzhuang Company. During the pressing of the tank shell plates, the company’s punching, shearing, assembly, and welding workshop overcame difficulties such as limited equipment capacity for pressing and high lifting challenges; by adopting innovative manufacturing techniques, they managed to complete the production tasks on time. In 2021, Lanshi Heavy Equipment undertook the design, manufacture, and installation of 14 spherical tanks for the olefin storage area in Baofeng Energy’s 500,000 tons per year coal-to-olefins project as well as the C2-C5 comprehensive utilization olefins production project. These tanks included 6 3,000 m3 propylene tanks, 2 2,000 m3 propane tanks, and 6 3,000 m3 ethylene tanks. Among them, the 3000 m3 ethylene sphere tank is designed for a temperature of -67°C and uses 66 mm thick 09MnNiDR steel plates; it is the largest thick-walled low-temperature steel sphere tank in China.
