Why Choose Our SiC Heat Exchange Tubes?
  • Superior Corrosion Resistance: Withstands harsh acids, alkalis, and solvents, making it ideal for aggressive chemical processes where metals and alloys fail.
  • Exceptional High-Temperature Stability: Maintains mechanical strength and integrity in continuous operation at temperatures up to 1650°C in air.
  • High Thermal Conductivity: Excellent heat transfer (196 W/m*K at room temperature) ensures maximum efficiency in heating or cooling applications.
  • Outstanding Thermal Shock Resistance: Withstands rapid temperature changes (>350 ΔT), preventing cracking and failure.
  • Excellent Wear & Erosion Resistance: The extreme hardness (2350 HV) provides a long service life in applications with abrasive slurries or particulates.
  • Fully Dense & Impermeable: Near-zero open porosity prevents gas or fluid permeation, ensuring product purity and structural reliability.
