Safety first! Prevention first! Reply reward! ---------------------------------------------- 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 engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! ================================= Recently, the hydrostatic testing and sizing equipment for Φ114.3–Φ339.7 at Chengde Jianlong Special Steel Co., Ltd., as well as for Φ76–Φ245 at Pangang Great Wall Special Steel Co., Ltd., which were supplied in their entirety by China National Heavy Machinery Research Institute Co., Ltd. (hereinafter referred to as “China National Heavy Machinery Research Institute”), passed the thermal load test successfully on the first attempt. All performance indicators met the design requirements, earning high praise from the customers, and the equipment was successfully put into operation. 　　Both sets of equipment utilize a range of advanced and mature technologies developed by the China National Heavy Machinery Research Institute, such as elbow-type water filling systems, automatic positioning exhaust systems, and automatic pneumatic passage mechanisms, ensuring efficient and stable production for users ； At the same time, the hydraulic system features a servo control system, which enables energy savings of over 50% compared to traditional systems and reduces noise by 40%, **improving the production environment at the user’s site.
