SSiC (pressureless sintered silicon carbide) tubes are advanced ceramic components known for their exceptional mechanical strength, corrosion resistance, and thermal stability.
Produced through pressureless sintering, SSiC tubes offer high density and superior performance in harsh industrial environments.
Key Features:
Outstanding corrosion resistance to acids, alkalis, and most chemicals
Excellent thermal conductivity and stability under high temperatures (up to 1700°C)
Superior wear and abrasion resistance
High mechanical strength and stiffness, even at elevated temperatures
Long service life in aggressive operating conditions
Typical Applications:
Thermocouple protection tubes in high-temperature kilns and furnaces
Heat exchanger tubes in corrosive chemical processes
Tubes for semiconductor and photovoltaic manufacturing equipment
Components in metallurgy, petrochemical, and environmental industries
As structural parts in the kiln to support the kiln plates.
