The seamless steel pipe is used to replace the seamed steel pipe, and then welded to the cast steel die head to reduce the solder joints and welds as much as possible to increase the corrosion resistance of the radiator. The screen discards the welding process between the radiator and the sheet, and the threaded connection not only facilitates disassembly and assembly, but also eliminates the weld seam, again reducing the risk of corrosion. The new feature of the new anti-corrosion technology for steel radiators, the radiator screen discards the conventional method of anti-corrosion of the inner coating of steel radiators, and the precision cast steel heads formed by one casting minimize the welds and reduce the welds. Corrosion leakage risk, even in the most severe thermal shutdown, residual water is difficult to corrode 2.7 mm thick cast steel head, eliminating the risk of corrosion of the film head, completely solve the problem of steel radiator from the manufacturing process Corruption is easy to leak.
Tianjin Steel Radiator Factory pointed out that the steel three-column radiator (now renamed as steel column radiator) is an innovative revolution. Since then, steel radiators will enter the second generation development process. It is the introduction of the original welding process of the radiator. It has led the advancement of China's steel radiators. The cast steel radiator will create the brilliance of the radiator. The future trend will surely be the anti-corrosion concept of the cast steel radiator era. . We firmly believe that the brand is influenced by the excellent quality, not by advertising. The well-known products are not necessarily technologically advanced, because the society will develop new products in advance.
In 1980, the experts of the Ministry of Construction of the radiator industry introduced the most advanced European steel tube radiators. Later, some domestic companies introduced new type of composite steel tube radiators, which are suitable for the original imported products. Significant improvements have been made to quality defects. The water separator and the riser both reject the traditional process of rolling and forming a thin steel plate. The water separator of the radiator is made of precision cast steel, and the material is a rare earth modified cast steel with a wall thickness of 2.7 mm; the official is 1.5 mm. Seamless steel tubes, which are welded between the sheets and are threaded and threaded. The biggest feature is that the welding process is changed to the casting process, which reduces the total length of the weld by 95%--98%. At the same time, the material is improved and the wall thickness is increased, thereby reducing the risk of corrosion and making the entire radiator. The anti-corrosion ability is multiplied.
The steel four-column radiator eliminates the problem of easy corrosion when the water is shut down and the water is not full during operation, so that the steel tube radiator is out of the misunderstanding and desperation of internal paint and other anti-corrosion. Tested by the University of Science and Technology of China, it can withstand 20 years of continuous uninterrupted corrosion experiments with a theoretical life of 60 years. It not only has the characteristics of ordinary steel tube radiators, but also retains the advantages of heat dissipation and corrosion resistance of cast iron. In addition, it is 10%-30% higher than the heat of the same industry standard, and the pressure resistance is increased by 20%. The rare earth modified low carbon steel with the same properties as the 20 boiler steel is selected, and the thickness of the steel is increased by 20%--80%. There are also many features in energy conservation and environmental protection, especially the ability to withstand more than 1.2mpa, more suitable for high-rise buildings.
Tianjin Steel Radiator Factory refers to the characteristics of the new steel radiator: 1. The new steel radiator reduces the welding process of the steel pipe, increases the casting process, and shortens the total length of the weld by 95% to 98%. It fundamentally solves the problem of perishable and easy leakage of ordinary steel radiators, and doubles the corrosion resistance and service life. It can withstand continuous uninterrupted corrosion for 20-25 years, and the theoretical service life should be multiplied by 3, that is, 60 years. It is a durable active anti-corrosion product that does not require any passive anti-corrosion measures.
2. Compared with the traditional cast iron radiator, the steel three-column radiator is made of rare earth modified low carbon steel with the same properties as the 20 boiler steel. The thickness of the steel is increased by 20%--80%, and the overall strength and rigidity are greatly increased. Enhanced, sturdy and durable, not afraid of bumps. The screen abandoned the production process of sheet metal crimping and forming, and the new technology of precision cast steel, whether it is the air layer when heating, or the residual water during the warming, can not corrode 2.7 thick cast steel head, completely eliminate The risk of the film being corroded.
3. Replace the seamed steel pipe with a seamless steel pipe, and then weld it with the cast steel die head to reduce the solder joints and welds as much as possible to increase the corrosion resistance of the radiator. The screen discards the welding process between the radiator and the sheet, and the threaded connection not only facilitates disassembly and assembly, but also eliminates the weld seam, again reducing the risk of corrosion.
4, steel radiator has a high bearing pressure, from the industry standard 1.0mpa, to the corporate standard of 1.2mpa, increased by 20%, high pressure, no deformation, more suitable for high-rise buildings. Take the 3 steel round four-column radiator with a center distance of 600mm as an example. The heat dissipation per piece is 109.3W, which is 17% higher than the industry standard. The larger the center distance, the higher the height, the average is 10%-30%. 35% higher than cast iron radiators, a model for energy saving. And the amount of water is still small.
5. The advantages of light weight, high pressure, high heat, energy saving, environmental protection and beautiful appearance of steel tube radiators, combined with the advantages of cast iron radiators, is an innovative product that has been reborn, since then steel radiators will Enter the second generation of the development process. The surface is sprayed with a wide range of colors to create a high-gloss, matt, and wrinkle type that is both aesthetic and easy to clean. High-end products, mid-range price, compared with the same type of steel radiator, the material cost is high, but the price is not high, or even low, value for money.
