Breakthroughs have been achieved in major equipment technology, and domestic fluid machinery is now capable of taking on important tasks. “After more than two years of intensive preparation, we are finally pleased to welcome the 4th China International Fluid Machinery Exhibition – the largest, highest-quality, and most professional exhibition of its kind in the history of international fluid machinery exhibitions.” This exhibition also serves as a platform to showcase and exchange the achievements made by China’s fluid machinery industry in terms of the localization of major equipment over the past two years, indicating that this industry is already capable of competing on a global scale in certain areas. ”At 9 a.m. on October 28, the fourth China International Fluid Machinery Exhibition, which has attracted significant attention from the fluid machinery industry both at home and abroad, opened at the China International Exhibition Center. Sui Yongbin, president of the China General Machinery Industry Association, presided over the opening ceremony and delivered an opening speech. 　　Policy support drives industry development. This exhibition, regarded as the \"Olympics\" of the fluid machinery industry, has been held in Shanghai since its first edition in 2002, and six years have now passed since then. The exhibition area increased by a factor of four, going from 6,000 square meters in the first edition to 30,000 square meters in the fourth edition. The continuous expansion of the scale of this exhibition illustrates two things: first, the biennial China International Fluid Machinery Exhibition has gained recognition from peers both at home and abroad; second, it reflects the rapid development of China’s fluid machinery industry over the past few years. 　　Fluid machinery is closely related to various technologies and equipment that fall under the 16 key areas for development outlined in Document No. 8 issued by the State Council, including large-scale clean and efficient power generation systems, large-scale ethylene production facilities, large-scale coal chemical processing plants, large-scale cold and hot continuous rolling equipment for thin sheets, large-scale underground mining equipment, large-scale open-pit mining equipment, urban rail transit systems, and large-scale environmental protection equipment; it plays a crucial role in supplying the components needed for these important technological systems. 　　In recent years, driven by policies aimed at vigorously revitalizing the equipment manufacturing industry, Chinese manufacturers of fluid machinery have actively adopted advanced technical equipment, management concepts, and systems. Through digestion, absorption, and re-innovation, they have made significant progress in localizing key technical equipment. In particular, large-scale air separation units, ethylene triple units, and ethylene cryogenic tanks are now capable of competing with internationally renowned companies such as Demag from Germany, Novellis from Italy, Nippon Steel from Japan, KSB from Germany, Hitachi from Japan, GE from the United States, Ingersoll Rand, and Sulzer from Switzerland, thereby strongly promoting independent innovation in equipment for China’s petrochemical, power, and metallurgical industries. 　　The exhibits highlight industry progress. At the booth of Shenyang Blower (Group) Co., Ltd., large-scale images were used to show domestic and international visitors the breakthrough advancements the company has made in the field of million-ton ethylene cracking units – namely, the cracking gas compressor, ethylene compressor, and propylene compressor ； Shaanxi Blower (Group) Co., Ltd. showcased the first domestically developed \"axial-flow + centrifugal series compressors set for 50MW coal gas combined cycle power generation CCPP units\" technology. In addition, Shaanxi Gear Group also displayed its axial flow compressor units designed for large-scale metallurgical blast furnaces. In the fan exhibition area, key enterprises in the fan industry such as Shanggu, Wugu, Changgu, Jiaodaicail, Siping Blowers, and Jiangsu Jintongling also displayed their latest products, technologies, and manufacturing processes through physical samples, models, and pictures. 　　Air separation enterprises led by Hangyang Group have seen astonishing growth rates in recent years. Not long ago, the successful first commissioning of a large-scale air separation unit of 60,000 capacity provided by Hangyang for Baosteel marked the official entry of domestically produced air separation equipment into the ultra-large scale category. Kaifeng Air Separation Group Co., Ltd. not only showcased the achievements it has made in providing Hualu Hengsheng with the first set of large-scale air separation units of 40,000 capacity, but also presented its latest accomplishments in the localization of air separation units with a capacity of 82,000. Sichuan Air Separation (Group) Co., Ltd. displayed the achievements made in recent years regarding the localization of large-scale air separation technologies, while also introducing to visitors their latest advancements in gas technology. Sui Yongbin has said publicly that companies such as Shenpu, Shaanxi Gas Turbine, and Hangzhou Oxygen are now capable of standing among the best in the world and competing on equal terms with foreign-funded enterprises. ” 　　In the compressor exhibition area, Shanghai Compressor Factory displayed a large reciprocating compressor with a piston force of 100 tons. This compressor not only fills the gap in China for compressors with a piston force of 1 million tons or more, but also meets the needs of chemical industry users for high-tonnage reciprocating compressors. It is reported that the Gas Compressor Division of SHENGU Group is currently developing a 125-ton piston-type compressor. In addition, the twin-screw compressors displayed by Zhejiang Kaishan Group, the large diaphragm compressors shown by Jingcheng Environmental Protection Company, and the large natural gas compressors presented by Wuxi Compressor Company are all at the international advanced level. 　　The international competitiveness of pump and valve products has increased. In the pump and valve exhibition area, reporters observed that not only was the number of exhibitors higher than in the previous edition, but the technical level of the products on display was also increasing. 　　 　　In front of the booth of Shanghai Electric Power Repair and Manufacturing General Factory, the model of the country’s first domestically developed, integrated 1000MW thermal power plant boiler feed pump was displayed in the most prominent position of the booth. It is reported that with the rapid development of the national economy and the growing awareness of environmental protection, China’s power industry is expanding at an unprecedented pace. However, regarding the boiler feed pumps, circulation pumps, and condensate pumps used in ultra-supercritical thermal power units, although some domestic companies do produce such products, they still cannot meet the demands arising from the fast development of the power industry. Shanghai Electric Repair and Manufacturing Plant has successfully developed feed pumps for ultra-supercritical large-scale thermal power units, making another significant contribution to technological progress in the pump industry. 　　In the field of nuclear power, nuclear valve manufacturers such as China National Nuclear Su Valve Technology Co., Ltd., Shenyang Shengshi High and Medium Pressure Valve Co., Ltd., Dalian Dagao Valve Co., Ltd., and Shanghai Valve Factory Co., Ltd. have made breakthrough progress in the manufacturing of nuclear grade-1 valves. Among them, CNNC Su Valve has made significant breakthroughs in nuclear grade 1 DN100 electric quick-acting isolation valves, DN50 pressure regulator electric relief valves, as well as nuclear grade 2 DN200 electric quick-acting cast-steel isolation valves and DN1000 electric hard-sealed isolation butterfly valves. 　　In the field of ball valves for long-distance pipelines, companies such as Zigong High-Pressure Valve Co., Ltd. and Shanghai Lianggong Valve Co., Ltd. have seen rapid development in recent years. Among them, the fully welded line ball valves produced by Zigong High-Pressure Valve Co., Ltd. were recently successfully awarded a contract for use on the main line of the West-East Gas Pipeline Project II, marking that ball valves used in such long-distance transmission pipelines, which had long been under foreign monopoly, are no longer dependent on imports. 　　In addition, a group of private enterprises represented by Zhejiang Xuanda, Chaoda, Berthold, and Suzhou Newway Valve Co., Ltd. have risen rapidly and are able to play an important role in industries such as chemicals, power, and metallurgy. 　　The achievement of these results **has accelerated the upgrading of fluid machinery products in our country, improved the level of domestic production, reduced investment costs in engineering projects, and significantly enhanced the independent innovation capabilities and international competitiveness of China’s fluid machinery manufacturing industry.**
