High Light pressureless sintered SiC thermocouple tubes ,SiC ceramic thermocouple protection tubes ,high temperature corrosion resistant SiC tubes
Pressureless Sintered SiC Thermocouple Protection Tubes | For Extreme Temperatures & Corrosion
Product Description

Our pressureless sintered silicon carbide (SSiC) thermocouple protection tubes are engineered to provide reliable and durable temperature measurement in the most demanding industrial environments. Manufactured from high-purity SiC, they offer a superior combination of extreme temperature resistance, exceptional corrosion resistance, and outstanding thermal shock performance. These tubes effectively shield thermocouples from harsh conditions, ensuring measurement accuracy and significantly extending service life compared to traditional metal or ceramic alternatives.

Key Features & Superior Advantages
  • Withstand Extreme Temperatures
    • 1650 °C in air & 1900°C in inert atmospheres, far exceeding the limits of stainless steel (600-800°C).
    • Maintains high mechanical strength, with a flexural strength of 320 - 400 MPa even at elevated temperatures.
  • Superior Corrosion & Erosion Resistance
    • Excellent resistance to strong acids (HCl, HNO₃, H₂SO₄), molten metals (Zn, Sn, Pb), and corrosive gases.
    • Oxidation resistance is 7 times stronger than alumina ceramics at 1300°C.
    • Ideal for harsh environments with sulfur, tar, and high-velocity particulates.
  • Exceptional Thermal Shock & Wear Resistance
    • Low thermal expansion coefficient (4.0 * 10⁻⁶/K) minimizes cracking risks during rapid temperature changes.
    • Extreme hardness (Vickers Hardness 2350 kg/mm²) ensures long-lasting performance in abrasive conditions.
  • Optimized Thermal Response
    • High thermal conductivity (196 W/(m *K)) ensures rapid heat transfer, leading to faster response times and more accurate temperature readings.
