Silicon Carbide Tube
Silicon carbide (SiC) furnace tubes are widely renowned for their hardness, abrasion resistance, high flexing strength at elevated temperatures and good thermal conductivity. Furthermore, these chemical inert tubes offer corrosion-protection.
SiC is an ideal material choice for large shell and tube heat exchangers in the chemical process industry, being resistant to corrosion, acids, thermal expansion coefficient and shockproof.
Hardness
Silicon carbide is one of the hardest ceramic materials on the market. It has high fracture toughness and flexural strength, making it an excellent material choice for power industry components requiring extreme conditions to withstand severe conditions. Furthermore, silicon carbide offers chemical inertness, thermal conductivity, resistance to impact and abrasion resistance as well as chemical inertness properties.
SiC is an ideal material for use in ballistic armor applications due to its extreme hardness; ballistic projectiles need a material with enough strength to withstand high speeds of projectile travel and resist harm at close proximity. Sintered SiC is therefore frequently found within composite armor systems.
Hexoloy SE (sintered) silicon carbide tubes are an ideal material choice for shell and tube heat exchangers in the chemical processing industry, typically involving tube lengths exceeding 4 meters. They boast exceptional corrosion resistance, superior mechanical strength, good thermal conductivity and resistance to high temperatures as well as thermal shock; making it suitable for any pressure or vacuum application; they even withstand many acids and alkalis chemicals without corroding.
Corrosion Resistance
Silicon carbide resembles diamond in that it is one of the lightest, hardest and strongest industrial ceramic materials available. Additionally, its exceptional electrical properties, low thermal expansion rate and excellent resistance to acids and lyes make it a formidable material suitable for corrosion, abrasion and erosion resistance, making it suitable for components such as mills, expanders, extruders nozzles among other high performance machinery.
Corrosion resistance of sintered silicon carbide depends on several factors, such as impurities, sintering aids and grain boundary phases. Furthermore, its performance depends heavily on its environment - factors like humidity levels, temperature and acidity are also significant influences.
Pressureless sintered silicon carbide is widely recognized to be corrosion resistant, withstanding attacks from acids (hydrochloric, sulfuric, hydrobromic and hydrofluoric), bases (including caustic soda), solvents and aggressive chemicals that are often encountered in mining, metal smelting, steel processing, oil refining and aerospace industries. As such it makes an attractive material choice.
High Temperature Resistance
Silicon carbide ceramic tubes can withstand high temperatures, making them an excellent choice for use in hostile environments. Furthermore, their corrosion and abrasion resistance make them perfect for applications including shot blast nozzles and cyclone components.
Silicon Carbide Radiant Tube (SiC) is an ideal heat transfer product designed for tunnel kilns, shuttle kilns, roller kilns and other fuel gas/oil industry furnaces. With high temperature resistance, corrosion oxidation resistance, good thermal conductivity properties and long operational lifespan. It possesses all these attributes together for optimal performance in tunnel kilns, shuttle kilns, roller kilns as well as other fuel gas and oil furnaces.
SiC is an extremely hard synthetic material with a Mohs hardness of 9, approaching that of diamond. This allows SiC to be formed into many specialty-shaped structural parts like beams, rollers, cooling air pipes, thermocouple protection pipes, burner nozzles and wear-resisting and corrosion-resisting parts - these being beams, rollers, cooling air pipes thermocouple protection pipes thermocouple protection tubes burner nozzles as well as wear-resistant and corrosion-resisting components; further increasing hardness through thermal treatments.
Long Life
XICAR sintered silicon carbide ceramic thermocouple protection tube stands out for its superior thermal conductivity, electrical semi-conductivity and chemical resistance properties. Furthermore, its strength remains uncompromised even at temperatures up to 1400degC.
Sintered silicon carbide ceramics offer an unmatched combination of properties that makes them an excellent material choice for industrial applications involving extreme heat. For instance, sintered silicon carbide ceramics are often employed as protective tubes for thermocouples in aluminum and non ferrous metal smelting furnaces.
Brick kilns, ceramic kilns and other applications in which temperature sensors may be exposed to aggressive environments are also an ideal fit for pressureless sintered silicon carbide temperature sensors, due to their resistance against oxidation, corrosion and attack from non-ferrous metals such as aluminum. In comparison to reaction bonded silicon carbide products, pressureless sintered silicon carbide offers greater strength, high temperature resistance and low coefficient of thermal expansion - qualities essential for optimal performance of ceramic-lined steel pipe applications in demanding environments.
