Director Li Rufeng elaborated on five aspects: First, the process of airport project declaration. (Unyielding, hard work, painstaking efforts, 27 days of victory to complete the military approval) Second, the significance of airport construction. (The airport is a new source of power for national development) 3. The introduction of the city in Ezhou. (From the mode of transportation to urban development) Ezhou Airport predicts that the cargo and mail throughput will be 2.45 million tons in 2025, passenger throughput will be 1 million passengers, 153 stations will be stationed, 21 maintenance stations and 15,000 square meters of terminal buildings. Supporting the construction of ancillary facilities such as air traffic control, communication, navigation, meteorology, firefighting and rescue, as well as transshipment center engineering, oil supply engineering, and SF Airlines base project.
Fourth, SF company introduction and aviation concept. 
V. The promotion of urban transformation and industrial development in Ezhou by “one city and two gamesâ€. (The era of economic development, quality change, efficiency change, and power change) is developing rapidly. The diamond industry must also advance with the times to adjust its economic structure, from high growth to high-quality transformation. At the same time, maintain the spirit of innovation and innovation for entrepreneurs. Only the spirit can change the sky!Fined Tube

Manufacturing Process
Yuhong Group supplies the highest quality welded finned tubes to any part of the world. The newly designed manufacturing facility, with our state-of-the-art high frequency resistance welding machines, enable us to perform large scale projects in reduced times.
The steel fin, that may be solid or serrated, is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces an homogeneous, clean and continuous fin-totube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.
There are some applications for which one or the other fin type is preferred. While in some cases fouling and cleaning considerations will favour solid fins, serrated fins are superior with respect to weight, compactness and price.
The use of high-frequency current results in very localised heating of the tube surface and the edge of the fin. This skin effect produces higher weld speeds, hence post-weld heat treatment is not considered necessary because of the superficial nature of the changes in the microstructure.
Tube bending:
Our finning machines are equipped with online single or duplex cold bending equipment that can manipulate both ends of tubes in a single operation, thus ensuring exact alignment of the ends. Our bending machines are capable of bending both bare or finned tubes with diameters from 31 mm to 76 mm.
Corrosion protection:
If required, the external surfaces of finned tubes can be treated with a protective coating. Our engineers are always ready to assist you with design considerations to meet your specific product needs.
