High Strength Tubes For High-temperature Kilns
Sisic kiln tubes provide excellent strength, thermal shock resistance, and oxidation stability—ideal for roller kilns and thermal processing of ceramics, powders, and catalysts.
SiSiC kiln tubes are advanced high-temperature ceramic components made from reaction bonded silicon carbide (RBSiC or SiSiC). These tubes are widely used in continuous kilns, roller kilns, and tunnel kilns, particularly in powder metallurgy, ceramic sintering, lithium battery cathode materials, and chemical catalyst manufacturing.
SiSiC offers an ideal combination of high thermal conductivity, excellent oxidation resistance, low thermal expansion, and superior mechanical strength under extreme temperatures—making it far more durable and efficient than alumina or mullite tubes.
High-performance kiln tubes made from reaction bonded silicon carbide (RBSiC/SiSiC), designed for extreme temperature stability in powder metallurgy, ceramic sintering, lithium battery materials, and catalyst processing.
Ensures efficient heat transfer and uniform temperature distribution in continuous kilns.
Withstands aggressive gases and prolonged thermal cycling without degradation.
Low thermal expansion maintains precise alignment under fluctuating high temperatures.
Options include open/closed ends, flanged or stepped designs, and precision holes or grooves.
Compatible with alumina seals, insulation sleeves, and metal connectors for system integration.
Reduces maintenance cycles and boosts kiln performance in high-demand thermal systems.
Silicon carbide products are an advanced material widely used in high temperature, high pressure and high frequency environments.:
Composite structure with ordinary steel outer wall meets strength requirements for various industrial processes.
Inner ceramic layer (≥95% content) provides 30x better wear resistance than carbon steel pipes.
Corrosion-resistant composite layer enables use in acid, alkali, and salt environments.
Organic polymer matrix with inorganic ceramic reinforcement provides 14-16 MPa peeling strength (100x stronger than ordinary lining).
Continuous operation from 40°C to 200°C, with peak resistance up to 260°C.
Elbows show no significant wear after 1-2 years, outperforming thick-walled cast steel by nearly 10x.
Silicon carbide ceramic-lined pipes offer superior performance compared to traditional materials:
Our silicon carbide tubes and fittings are carefully packaged to minimize damage during storage and transit, ensuring the original quality remains intact.
We implement anti-vibration and impact-resistant measures to ensure each product arrives safely. Packaging methods are adapted for maritime transport, with corrosion-resistant wrapping and clear identification labels.
Understanding the differences between reaction bonded and pressureless sintered silicon carbide
Reaction bonded silicon carbide offers the lowest cost production technique with excellent overall performance characteristics.
Compared with reaction bonded silicon carbide, pressureless sintered silicon carbide offers superior performance in demanding applications.
