Silicon carbide protective tubes are high-performance, high-temperature resistant ceramic products made primarily of silicon carbide (SiC). They possess excellent high-temperature resistance, oxidation resistance, thermal shock resistance, and corrosion resistance. Their maximum operating temperature can reach over 1600℃, and they exhibit good thermal conductivity, high mechanical strength, and maintain stable physical and chemical properties even in high-temperature environments. Compared to metal protective tubes, silicon carbide is less prone to oxidation and deformation, resulting in a longer service life, making it particularly suitable for harsh working conditions.
Silicon carbide protective tubes are primarily used for external protection of temperature-sensing elements such as thermocouples and temperature sensors, preventing them from being corroded by oxidation, corrosive gases, or molten metal in high-temperature furnaces, ensuring the accuracy and stability of temperature measurement data. They are widely used in the metallurgical industry (such as steel and non-ferrous metal smelting), the glass industry, ceramic firing furnaces, high-temperature chemical reactors, and boiler systems in the power industry. In molten metal environments such as molten aluminum and copper, silicon carbide protective tubes effectively resist corrosion, improving equipment operational safety.
In addition, σωλήνες καρβιδίου πυριτίου also have excellent wear resistance, making them suitable for high-temperature flues, hot air ducts, and other applications requiring high-strength heat protection. With the development of industrial high-temperature technology, silicon carbide protective tubes, due to their energy-saving, durable, and stable characteristics, are becoming an indispensable component in high-temperature measurement and control systems.
