The new radiators are divided into four categories according to their materials: steel radiators, aluminum radiators, copper radiators, and copper-aluminum composite radiators.
Steel radiator
The steel radiator has originated in Europe and has a history of several decades. It entered the Chinese market at the end of the 20th century. In 1987, the HVAC Design Manual edited by Lu Yaoqing of the Northwest Architectural Design Institute of China recommended the use of SEMEM heating radiator products, which is a national standard. Atlas products. The appearance is beautiful, completely changing the rough appearance of the traditional cast iron radiator; the thickness of the radiator is thinner, the thickness is only 5 cm, which occupies less room space; the variety of shapes meets the needs of modern people to pursue individuality; the color is rich and adapts to different Color home decoration style; light weight, small water capacity, and more environmentally friendly use;
The disadvantage is: if the internal anti-corrosion process is not adopted, the radiator will leak and leak;
Aluminum radiator
Most of the aluminum radiators sold in the Chinese market are extruded aluminum profiles and welded radiators. The strength of the solder joints of some manufacturers can not be guaranteed, and problems are easy to occur and water leakage is caused. In addition, aluminum radiators are not suitable for alkaline water quality. The reason is that aluminum reacts with alkali in water, causing alkaline corrosion, causing perforation of aluminum and leakage of radiator. The aluminum radiator is simple in shape and poor in decoration, and is a low-end radiator.
Compared with steel radiators, aluminum radiators have lower prices due to differences in raw materials and manufacturing processes; fast heat dissipation and light weight; aluminum radiators have the disadvantage of causing alkaline corrosion in alkaline water. Therefore, it must be used in acidic water (pH <7), and most boiler water PH values ​​are greater than 7, which is not conducive to the use of aluminum radiators.
Copper radiator
Copper has high strength of general metal; at the same time it is not easy to crack and not easy to break; and has certain anti-frost and impact resistance; the reason why copper has such excellent and stable performance is due to the low order of copper in chemical sorting. It is only higher than silver, platinum and gold. It has stable performance and is not easily corroded. Due to the strong corrosion resistance of copper pipe fittings, no impurities are dissolved in the water, which keeps the water clean and hygienic. Therefore, the copper tube heating in the heating system in the building is safe and reliable, and even requires no maintenance and maintenance. Copper pipes and fittings retain their shape and strength at high temperatures without long-term aging. In the presence of high heat, high pressure, near fire and corrosion, the use of other pipe fittings, the user is always worried, fear of accidents. But with the use of copper fittings, you don't have to be scared, you can rest assured. Never corrode and durable.
Disadvantages of copper radiators: higher prices.
