The silicon carbide protection tube is a high-performance component designed to shield thermocouples and other sensing elements in extreme temperature and corrosive environments. Made from dense, reaction-bonded or recrystallized silicon carbide, the tube offers outstanding thermal conductivity, superior oxidation resistance, and long-term dimensional stability under continuous use up to 1,600 °C.

Its robust mechanical strength and chemical inertness make it ideal for harsh industrial applications such as metal smelting, ceramics firing, powder metallurgy, and semiconductor diffusion furnaces. Unlike traditional ceramic tubes, silicon carbide tubes exhibit excellent resistance to thermal shock and aggressive process gases, extending sensor life and reducing maintenance downtime.
