With the development of the fuel industry and the emergence of new technological processes, industrial furnaces using Silicon Carbide Radiation Pipes as heating devices have gradually developed. The use of radiant tubes as heating devices in industrial furnaces can not only reduce infrastructure costs and operating costs, improve furnace productivity, and extend furnace life, but also heat products with high quality. It can be said that the heating of the ejector tube effectively avoids the oksidesen na dekarbureisen bilong pes bilong ol hat hap na i opim wanpela bikpela lukluk bilong proses bilong tritim hat insait long wanpela protektiv atmosfera.

Samting
Silicon Carbide Radiation Pipes almost remain unchanged at very high temperatures (about 1600℃) and can maintain high strength for a long time. This material exhibits extremely high corrosion resistance in acid and alkaline media, so it is very durable. At the same time, the product is hard, with a Mohs hardness of about 9. It is a hard material among non-metallic materials, second only to daimon.
