The reporter learned from the Rui'an Coastal Industry Construction Office that after a preliminary negotiation between the domestic well-known auto company Shaanxi Automobile Group and the Yunding Holding Group of the city, it intends to expand production on the basis of the original cooperation platform, Shaanxi Auto Group Wenzhou Yunding Automobile Co., Ltd. The production of 60,000 medium- and heavy-duty trucks has settled in the automobile and motorcycle industry base in Ruian.
After Shaanxi Automobile Group's medium and heavy truck production bases settled in Ruian City, it is planned to introduce and establish engine plants, gearbox factories, frame factories, and body factories in phases. “Ruian City is the capital of China's automobile and motorcycle fittings, and the on-site purchase rate of car parts and components can reach more than 60%. Therefore, Shaanxi Automobile Group can use the local procurement of auto parts and components to reduce the supporting costs.†Ruian Coastal Office is responsible for one. Person.
If the medium- and heavy-duty trucks are calculated at 250,000-300,000 yuan per vehicle, the total industrial output value will reach 15 billion-1.8 billion yuan after the project is put into production, which will drive the output value of the auto parts industry from 45 to 54 billion yuan.

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.
