Pressureless sintered silicon carbide (SiC) thermocouple protection tubes are high-performance ceramic tubes fabricated from high-purity SiC using a pressureless sintering process. Their key advantages include high strength, exceptional high-temperature resistance, superior corrosion resistance, and excellent thermal shock resistance, making them ideal for temperature measurement in extreme industrial environments. They provide long-term, stable protection for thermocouples against physical and chemical degradation.
Typical application:
Metallurgy
Temperature measurement in molten steel, iron, copper, and aluminum, replacing traditional metal tubes to reduce replacement costs.
Chemical and Energy Industries
High-temperature gas turbines, waste incinerators, and sulfur incinerators operating in corrosive gas environments.
Ceramics and Glass Manufacturing
Internal temperature monitoring in glass furnaces and ceramic kilns to ensure process stability.
Semiconductors and New Energy
Temperature control in high-temperature reactors and salt bath furnaces used in lithium-ion battery and photovoltaic production.
Feature:
High-Temperature Resistance
Maximum operating temperature: Up to 1,650°C in air and 1,900°C in inert gases, significantly exceeding traditional metal protection tubes (e.g., stainless steel, which withstands only 600–800°C).
Thermal stability: Maintains a flexural strength of 380 MPa, preventing deformation or fracture under high temperatures.
Corrosion and Oxidation Resistance
Chemical stability: Resistant to strong acids (e.g., hydrochloric, nitric, sulfuric acid) and molten metals (e.g., Zn, Sn, Pb) without corrosion, with oxidation resistance surpassing that of alumina ceramics (7× stronger at 1,300°C).
Erosion resistance: Suitable for environments containing oxygen, sulfur, tar, and other corrosive media, such as high-temperature combustion gases and fuel oils.
Thermal Shock and Wear Resistance
Coefficient of thermal expansion: 4.85 × 10⁻⁶/°C, closely matching metal thermocouples to minimize cracking risks caused by thermal expansion mismatches.
Wear resistance: Vickers hardness of 2350 kg/mm2, enabling resistance to high-velocity fluid or particle erosion for extended service life.
Thermal Conductivity
Thermal conductivity: 160 W/(m·K), ensuring rapid heat transfer to the thermocouple for short response times and high measurement accuracy.
