Introduction of Reaction bonded silicon carbide radiant pipe :

Our Reaction bonded silicon carbide radiant pipe is one of the common industrial heating devices. Gas is burned in a sealed tube and transfers heat to the heated object in the form of thermal radiation through the heated tube surface, burning the flue gas. It does not come into contact with the heated object and will not cause pollution to the product quality by the combustion atmosphere and products. Reaction bonded silicon carbide radiant pipe is very suitable for occasions that require high product quality. RBSiC Radiant tube is suitable for indirect combustion furnace, self-preheating combustion furnace, famous fire combustion furnace, tempering furnace, annealing furnace, quenching furnace, incineration furnace and other pretreatment or heat treatment equipment heat conduction device and heat dissipation device.

Advantages of SiSiC Radiant tube :

1.Our SiSiC Radiant tube has high hardness and density, and has strong wear resistance.

2.This Reaction bonded silicon carbide radiant pipe is resistant to high temperatures and corrosion.

3.SiSiC Radiant tube not only has excellent performance, but also has ultra-high service life.

Applications of RBSiC Radiant tubes‌

RBSiC Radiant tubes are transforming industrial heating systems, combining unparalleled material properties with energy-efficient performance. These components, manufactured through reactive sintering of silicon and carbon, excel in environments where conventional metallic or oxide ceramic tubes fail.

‌1. High-Temperature Heat Treatment‌

RBSiC Radiant tubes operate continuously at 1350°C, making them ideal for:

‌Annealing furnaces‌: Uniform heat distribution improves steel microstructure consistency

‌Brazing systems‌: Tolerance to thermal cycling prevents warping in aerospace component production

‌Sintering atmospheres‌: Gas-tight structure maintains hydrogen/N₂ purity in powder metallurgy

A 2023 study showed RBSC tubes in automotive gear hardening lines reduced energy consumption by 18% versus nickel-based alloy alternatives.

‌2. Corrosive Industrial Environments‌

The RBSiC Radiant tube's chemical inertness enables use in:

‌Chemical vapor deposition (CVD) reactors‌: Resistance to HCl/Cl₂ gases extends service life by 3× vs. alumina tubes

‌Aluminum melting furnaces‌: Withstands molten aluminum splashes and fluoride vapors at 850°C

‌Waste incinerators‌: Minimal degradation from sulfur oxides and alkaline ash

‌3. Energy Recovery Systems‌

RBSiC Radiant tube's high thermal conductivity (120–140 W/m·K) enhances heat transfer efficiency in:

‌Cogeneration units‌: 95% heat recovery rates in glass tempering exhaust systems

‌Cracking furnaces‌: Preheats petrochemical feedstocks 40% faster than Si₃N₄ tubes

‌Regenerative burners‌: Thin-walled designs (3–5 mm) reduce radiative heat loss by 22%

‌4. Sustainable Manufacturing‌

Aerospace manufacturers report:

50% reduction in tube replacement frequency vs. metal alloys

30% lower CO₂ emissions due to improved combustion stability

Compatibility with hydrogen fuel blends, supporting decarbonization initiatives
