Silicon Carbide Radiation Pipes serve as core heating elements in high-temperature industrial applications. Shandong Qishuai Wear-Resistant's premium-quality Silicon Carbide Radiation Pipes revolutionise conventional metal heating elements through exceptional high-temperature resistance (>1600℃) and thermal efficiency. Across industries including ceramic sintering, semiconductor manufacturing, and metallurgical heat treatment, our Silicon Carbide Radiation Pipes reduce energy consumption by 30% while extending service life by 2-3 times.
Silicon carbide radiation tubes, being indispensable parts of contemporary industrial high-temperature appliances, are already dominating in many fields and becoming the key driving force to maintain stable and high-quality production in a large number of industrial processes as they offer a multitude of performance benefits.Not ordinary pipes, Silicon carbide radiation tubes are the assurance of stable and high-quality production.
Product Highlights
Resistance to Extreme Environments
Melting point of ≥2700°C, easily withstand the operating temperature of >1600℃(normal operating temperature range is generally 1100-1200℃ for stainless steel pipe).
Resistant to acidic/alkaline furnace gases such as HCl, SO₂, no oxidation or embrittlement occurred, more brittle than silicon carbide material.
The thermal expansion coefficient is only 4.5×10⁻⁶/℃, which can resist cracking when subjected to rapid thermal cycling.
Energy and economics.
thermal emissivity >0.9 (the thermal emissivity of metal pipe is about 0.7), increase the thermal conversion efficiency by 40%.
long service life, the service life is 20,000–50,000 hours (the service life of metal pipe is about 8000 hours), maintenance cost can be reduced by 50%.
Environmental friendliness and compatibility.
No heavy metal contamination, conform to the EU RoHS standard.
Can be powered by electricity or natural gas as energy sources, help enterprises achieve carbon neutrality goals.
Fields of application
Silicon carbide radiation tubes, owing to their exceptional performance, play an indispensable role across multiple critical industrial sectors, establishing themselves as the ideal choice for numerous high-temperature processes.
