Changsha Weizhong Chemical Machinery Co., Ltd. was restructured from the former Changsha Chemical Machinery Factory. The company's predecessor, Changsha Chemical Machinery Factory, was founded in 1958. It is a key backbone enterprise of the former Ministry of Chemical Industry, known as the "Four Dragons" enterprise of the Ministry of Chemical Industry. In December 1995, he joined the China Chemical Machinery Group (a close-level enterprise) of the Ministry of Chemical Industry. In 1996, he formed Changsha Tongda Group, a state-owned medium-sized enterprise. In November 2003, the enterprise was restructured and renamed as Changsha Weizhong Chemical Machinery Co., Ltd. In 2019, Changsha Boneng Technology Co., Ltd. wholly acquired Weizhong Chemical Machinery Co., Ltd. Through this acquisition, it took the advantages of the other party to make up for its shortcomings, so as to make the company's product structure multi-level and scale production and operation, integrate all the company's resources in market development, procurement and other business negotiations, improve the market position, and improve the company's comprehensive market competitiveness. Let the company retain the good tradition of standardized management of state-owned enterprises, while also having the flexibility of private enterprises.
The company has nearly 70 years of experience in the design and manufacture of special equipment, and has long been engaged in the research, design and manufacture of industrial equipment such as chemical, petroleum, metallurgy, pharmaceutical, food, building materials machinery, turnkey projects of CO2 supercritical extraction complete sets, energy-saving equipment (industrial steam turbines, circulating compressors, water turbines), etc. It is the director unit of China Chemical Equipment Association, one of the top 100 chemical equipment enterprises in China, and the designated design and manufacturing unit of national special equipment. The company is located at No. 18, Panpan Road, Changsha Economic and Technological Development Zone (Xingsha), Hunan Province. It is adjacent to the Wuhan-Guangzhou Railway Expressway in the east, the Beijing-Guangzhou Railway in the north, the Beijing-Zhuhai Expressway in the north, and the Xianing New Port in Changsha in the west. The water and land transportation is very convenient. It covers an area of 150 mu, has a registered capital of 140 million yuan, and has more than 500 employees, including 20 senior engineers, 50 engineers, and 50 senior technicians. It has curling blanking, mechanical processing, riveting and welding equipment, heat treatment, surface corrosion protection and other equipment, a complete set of manufacturing workshops, technology development departments, welding laboratories and other research and test institutions, and has complete measurement and verification, physical and chemical metallography, and nondestructive testing and other testing means, More than 600 manufacturing and testing equipment ensure the safety performance and manufacturing quality of products from the technological level and equipment capacity.
Weizhong Chemical Machinery Co., Ltd. is one of the earliest large-scale high-pressure vessel design and manufacturing enterprises in China. Special attention is paid to the research and development and application of new technologies, new processes and new materials of products. Through continuous efforts, a large number of new technologies and products, represented by large-diameter high-voltage equipment, with advanced domestic and foreign levels and unique advantages, have been developed. New breakthroughs have been made in temperature and corrosion resistant materials such as high alloy steel, high temperature steel, low temperature steel, duplex stainless steel, etc. The equipment produced with different materials and different requirements has become the company's leading products, making a great contribution to the development of domestic special equipment.
The overall multi-layer clamping high-voltage equipment manufacturing process jointly developed and developed by the company and the South China University of Technology has won the third prize of the National Science and Technology Progress Award, the National Spark Program and the Gold Award of the National "Seventh Five-Year Plan" Major Technical Equipment Expo. This process has reached the international advanced level, filled the gap in the manufacturing of domestic special equipment, and won the only recommendation of the General Administration of Quality Supervision, Inspection and Quarantine on the production mode of high-voltage equipment; It is the drafting unit of the industry HG3129-1998 standard of "Integral Multilayer Clamping High Pressure Vessel", and also participated in the national major technical equipment research project "Research on the Application of Steel for - 70oC Low Temperature Pressure Vessel" jointly organized by relevant national ministries, commissions, professional institutes and other units, which has achieved a complete success, making the production and manufacturing of low temperature equipment realize localization, and greatly improving the company's market competitiveness.
Looking forward to the future, Weizhong Chemical Machinery will focus more on the business with sustainable development, and strive to provide customers with safer, environmentally friendly and high-quality products through continuous technological innovation. Adhere to the spirit of "where products go, where services go", and wholeheartedly provide customers with "zero worry" product services. We look forward to working with you to create a better future!
