Silicon carbide tubes are highly-specialized components utilized in various industrial and commercial settings. Their resistance to high temperatures, wear, corrosion, oxidation, strength and longevity makes them invaluable components.

Silicon Carbide is one of the lightest, hardest, and strongest industrial ceramic materials available. With an exceptionally high Young's modulus value and exceptional dimensional stability and chemical inertness qualities.

High Temperature Resistance

Silicon carbide possesses exceptional resistance to extreme temperatures and pressures, making it the ideal material for environments subject to such extreme conditions. As such, silicon carbide tubes can withstand corrosion and oxidation effectively, remaining structurally stable across a broad spectrum of operating environments.

These tubes can be utilized in numerous industrial applications, including carburizing, nitriding and annealing furnaces. Furthermore, these tubes make an excellent choice for heat treatment furnaces as they offer efficient heating that ensures uniform metallurgical properties in treated materials.

Hexoloy SE sintered SiC tubes are known for their extreme thermal shock resistance and come through stringent quality testing and inspection, including hydrotesting at pressures between 165-186 bar.

High Strength

Silicon carbide boasts excellent abrasion- and corrosion-resistance. Furthermore, its strength and durability enable it to withstand extreme temperature fluctuations without losing strength. Young's modulus and flexural strength ratings are high while its hardness of 32GPa makes it one of the hardest materials known.

Chemical Processing Its SiC tubes are commonly employed in chemical plants to transport liquids and gases with high levels of corrosion. Furthermore, these pipes can also be found used for power generation applications to transport superheated steam as well as other high temperature gases.

Hexoloy SE sintered silicon carbide is an ideal material for use in shell and tube heat exchangers used across various thermochemical environments, offering excellent corrosion resistance, hardness and mechanical strength as well as thermal conductivity and low coefficient of expansion. Available in a wide range of diameters and lengths.

Excellent Corrosion Resistance

Silicon carbide's chemical inertness allows it to withstand even the harshest environments without succumbing to corrosion, making it particularly suitable for chemical processing or high temperature corrosive applications. Kerui silicon carbide tubes are known for their superior resistance against wear and abrasion.

Silicon carbide is an excellent choice for high-temperature equipment, whether as protection components or furniture. They're especially suited to medium frequency forging and heat treatment furnaces as well as being used in metallurgy, the chemical industry and non-ferrous metal smelting processes.

SiC is unique among ceramic materials in that it can be applied across an extensive temperature spectrum without altering its performance, offering exceptional service life due to its superior strength, corrosion and oxidation resistance, excellent thermal conductivity and low expansion coefficient.

Low Expansion Coefficient

Silicon carbide tubes feature a much lower thermal expansion coefficient compared to graphite, tantalum and stainless steel materials, making for easier handling and longer operational lifespan in environments featuring extreme temperatures, corrosion and oxidation.

These tubes can be utilized in a variety of metallurgical applications, as well as medium-frequency forging furnaces, various electric heating elements and other heat treatment furnaces. Their acid resistance, alkali resistance and oxidation resistance is outstanding and chemical stability is exceptional.

Elkem's sintering process produces silicon carbide of the highest quality, featuring low expansion coefficient, superior chemical corrosion resistance, wear resistance, and hardness characteristics that make it suitable for pump and component components that operate in harsh environments. These products undergo careful inspection during manufacturing via scanning electron microscopy to analyze microstructure details as well as mechanical testing to test strength and quality.

High Thermal Conductivity

Silicon carbide stands out as being exceptionally hard, yet still exhibits excellent thermal conductivity. This allows for improved heat dissipation and reduced strain on other parts of your system, creating more energy-efficient ceramic components.

SiC's high thermal conductivity can be partially attributed to its low density and lack of impurities, both contributing to its excellent thermal conductivity. However, the mean free path of heat carrying phonons may also be affected by alloying elements, vacancies, crystal defects and stacking faults that reduce their free path lengths and therefore their thermal conductivity.
