Silicon carbide heat exchange tube

  • Finished product characteristics

    ● High strength ● High hardness ● High wear resistance ● High temperature resistance ● High corrosion resistance, ● Good thermal and seismic resistance ● High thermal conductivity and high oxidation resistance, superior performance

  • Product characteristics

    The quality of SIC tubes has a significant impact on the tubular silicon carbide heat exchanger, using pressureless sintered silicon carbide material (SSiC) without free silicon. The tube type silicon carbide insert high-temperature heat exchanger is designed to replace metal heat exchangers, with shapes such as circular, square, U-shaped, etc. It can be customized according to customer needs.

  • Precision machining

    1. High purity silicon carbide powder

    2. Open mold processing: dry pressing, CIM injection molding, isostatic pressing.

    3. Appearance processing: surface grinding, outer diameter/inner diameter grinding, fine engraving machining, grinding, polishing grinding.

  • application area
