Shaanxi Province has long been a key base for equipment manufacturing in China. During the "First Five-Year Plan," "Second Five-Year Plan," and the "Third Line" construction periods, the state established numerous large-scale manufacturing projects in Shaanxi. Over time, the province gradually developed into a relatively complete industrial system covering general and specialized equipment manufacturing, defense, aviation, and aerospace. Following the release of the State Council's "Several Opinions" on revitalizing the equipment manufacturing industry, Shaanxi saw this as a crucial opportunity to boost its industrial sector. In recent years, the province has focused on several key areas to promote development. First, it formulated an equipment manufacturing plan under the "Eleventh Five-Year Plan." The province identified eight key sectors, including aircraft manufacturing, aerospace equipment, automotive production, power transmission equipment, construction machinery, CNC machines, communication and electronic devices, and special equipment. Major enterprises such as Xidian, Xifei, and Shaanxi Automobile Group were prioritized, with Guanzhong and Hanzhong regions developed into core manufacturing centers. Second, policies and measures were introduced to support key industries. Efforts were made to enhance the transformation of scientific and technological achievements, increase investment, and improve financial support for manufacturers. Special investment companies were set up to provide capital and policy backing for growth. To support the development of China’s large aircraft, Shaanxi strengthened the Yanliang Aviation High-tech Industrial Base. Research was also conducted on 1000 kV high-voltage AC and ±800 kV DC transmission systems to meet national energy needs. Additionally, the province promoted cross-regional reorganization among metallurgical equipment companies to enhance competitiveness. In terms of technological innovation, the government increased investments in R&D centers and encouraged enterprises to master core technologies through technology absorption, international cooperation, and mergers. It also supported the establishment of research institutions by overseas returnees and foreign enterprises. To develop clusters, the province encouraged social capital participation in state-owned enterprise reforms and promoted cross-industry and cross-regional reorganizations. This helped build stronger industrial ecosystems. Talent development was another focus. Universities and vocational schools were strengthened to cultivate skilled workers and technical experts. Training programs were expanded, and efforts were made to improve working conditions and create better incentives for professionals. Finally, the government emphasized leadership and policy support. A leading group was formed to implement the revitalization plan, coordinate major issues, and ensure smooth project execution. Additional funding was allocated, and preferential policies were introduced to foster a favorable business environment. In conclusion, the implementation of the "Several Opinions" requires further refinement and supportive policies at the national level. It is recommended that key sectors receive more attention, historical burdens be addressed, and R&D coordination be improved to achieve technological breakthroughs during the "11th Five-Year Plan" period.

Finned Tubes

A finned tube is a heat transfer device consisting of many parallel metal fins commonly used for heat dissipation and cooling applications. Finned tubes increase the surface area of the pipe, thus increasing the heat transfer efficiency. Finned tubes are commonly used in applications such as air coolers, automotive radiators, condensers, and evaporators. They are also used in industrial heaters and refrigerators to increase heat transfer surface area and improve efficiency.

Finned tube is a kind of new, wear-resistant, efficient heat exchange material, is a kind of energy-saving heat exchange element, it uses high-frequency power source as heat source, the steel strip, steel pipe heating at the same time, so that the fusion welding together into one, with high heat exchange efficiency, large cooling area, long service life, adapt to a wide range of temperature, high pressure characteristics, it can also be made of a variety of materials, Excellent heat transfer, durability, heat resistance and corrosion resistance. Widely used in waste heat recovery, petrochemical, power plant boiler, economizer, bus, industrial and civil construction heating, refrigeration, medical drying, wood drying, food drying system and other industries.

The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
