Heat Exchange Tube
With its high thermal conductivity, resistance to high temperatures, strong corrosion, wear, and low thermal expansion, silicon carbide (SiC) heat exchange tubes can replace metals, graphite, and glass-lined materials in demanding conditions involving high temperatures, severe corrosion, and particulate matter. They are widely employed in chemical processing, metallurgy, and kiln waste heat recovery applications. Common engineering systems comprise die-press sintered (DX201) and reaction sintered (DX101) variants, capable of sustained operation at temperatures of approximately 1600–1700°C. They maintain high flexural strength (around 500–600 MPa) even at 1400°C, with thermal conductivity typically reported at 120–270 W/m·K (dependent on density and crystalline structure). These properties confer significant advantages in high-temperature corrosion-resistant heat exchange applications.
