Radiator has become the main radiator product promoted by the national configuration department, and it is also the radiator with the highest market share in China. After several years of practical use, the invention of steel pipe radiators is not enough in the United States and China, that is, after the steel pipe radiators are placed and used for a period of time, it is easy to have leakage at the welds. In order to guard against the corrosion and leakage of radiators, various adjustment and retention measures have been studied one after another, such as using various coatings to prevent corrosion inside the steel pipe radiators, adding magnesium rods to the radiators for protection against corrosion, and so on. So that the electronic radiator which can be used for active corrosion protection has become passive corrosion protection.
The difference in steel materials used, the difference in steel thickness, the difference in manufacturing process, and the difference in the number of welding joints and welds result in stronger anti-corrosion ability. Specifically, the head of the original imported product is formed by two pieces of 15mm thick steel plates respectively and then welded. The weld around the head is naturally formed, including the weld at the top of the head which is prone to water accumulation; The riser is rolled into a cylindrical shape with 125mm steel plate and welded into a steel pipe; And then the stand pipe and the sheet head are welded to form a single piece of the radiator; Finally, the pieces are welded to form a complete radiator. The new product first changes the welded head into precision cast steel formed by one-time casting, and the material is rare earth modified cast steel with a wall thickness of 2.7mm;
Secondly, the welded seamless steel pipe is changed into a high-quality low-carbon seamless steel pipe with a wall thickness of 15mm; Then, the film head and the seamless steel pipe are combined, and the automatic flash welding machine is used to pressurize and weld once to form a radiator; Finally, the seam connection between the sheets is changed to rib thread connection to form a group of complete radiators. The new manufacturing process completely discards the anti-corrosion essentials of the internal coating of radiators widely used in China, and directly selects the precision cast steel formed by one-time casting to prevent corrosion and leakage, which has multiplied the years of anti-corrosion and leakage.
Not only that, but also its heat dissipation capacity exceeds 10% - 30%, its pressure resistance increases by 20%, and its steel thickness increases by 20% - 80% compared with that of the same industry. It also has many characteristics in energy conservation and environmental protection. It not only retains the advantages of light weight, high pressure, high heat, energy saving, environmental protection and elegant appearance of steel pipe radiators, but also integrates many advantages of cast iron radiators. It is an innovative product that never dries. Since then, steel radiators will enter the second generation of growth process. The utilization of high-quality steel for new products, the increase of wall thickness and the elimination of welding joints and welds have eliminated a large number of perishable parts of the new products compared with the original imported products. After testing, it can withstand 20 years of continuous corrosion, and the theoretical service life is 60 years. It is a durable active anti-corrosion product without taking any passive anti-corrosion steps.
