Robust Construction With Silicon Carbide Tube

Silicon Carbide Tube (SSiC) is an impressive ceramic component known for its outstanding hardness and thermal stability, in addition to being widely known for its superior wear resistance and chemical inertness.

SSiC tubes can be found in a range of industrial applications. In particular, these tubing solutions excel when applied to power industry components requiring both abrasion resistance and corrosion protection.

Hardness

Silicon carbide is one of the hardest materials on Earth, boasting a Mohs hardness rating of 13. It ranks only behind diamond and boron carbide for hardness rating. Due to its extreme durability, silicon carbide makes an excellent material choice for applications where high mechanical stress or pressures may occur.

As it possesses high compressive strength, hardness, and modulus of elasticity qualities that make it suitable for ballistic protection systems, ceramic materials are an ideal choice when selecting armour materials for ballistic protection systems. They can stop projectiles during penetration while still absorbing any additional energy which allows it to provide effective protection with less overall product weight compared to other armour options.

Silicon carbide’s strong hardness and low thermal expansion allow it to be utilized in applications requiring refractories such as blast furnace linings. Furthermore, its resistance against extreme temperatures, corrosion and chemical attack make it an attractive material choice. In combination with its strength properties, silicon carbide makes an attractive material choice for numerous industrial and commercial uses.

Corrosion Resistance

Silicon carbide is one of the toughest ceramic materials on the market, offering exceptional corrosion, abrasion, erosion and frictional wear resistance. Furthermore, its low thermal expansion rate, high Young’s modulus value and exceptional chemical resistance make it suitable for use in demanding construction applications.

Pressureless sintered SiC has proven its resistance to acid attacks from all sources – hydrochloric, sulfuric and phosphoric acids; bases and solvents; all oxidizing media and abrasive acids such as lime and nitric acid – with excellent impact resistance against mating materials as well as superior shock resistance.

SSiC tubes are used in heat treatment furnaces for carburizing, nitriding and annealing processes due to their superior resistance against oxidation as well as corrosion and wear resistance. Furthermore, these energy efficient tubes enable quick heating and cooling cycles resulting in long service lives making SSiC an affordable long-term investment solution. They’re also frequently employed as sealing faces on pumps in environments including chemical processing/refining facilities, mining operations and pulp/paper processing plants.

Thermal Conductivity

Engineers and designers have long prioritized optimizing silicon carbide composite claddings for nuclear power reactors to minimize neutron absorption while providing excellent steam oxidation resistance, high temperature strength retention after neutron exposure and strength retention during neutron irradiation [1-4]. Unfortunately, thermal conductivity has received much less consideration, although its effects could significantly impact fuel temperature behavior and stress state.

Chemical-vapor-deposited SSiC features an extremely low oxidation rate, making it suitable for high-temperature environments with fluctuating temperatures. Furthermore, its low thermal expansion keeps dimensions stable despite sudden temperature shifts.

Hexoloy SE tubes are popularly employed in shell and tube heat exchangers used to manufacture float glass for chemical processes that require precise temperature regulation, such as producing it for chemical manufacturing processes such as those involving fermentation. Their superior thermal conductivity enables rapid heat dissipation into the glass bath without the need for large and costly cooling systems, leading to more reliable processes with improved operational efficiencies.

Weight

Silicon carbide furnace tube boasts superior corrosion resistance and strength, making it an excellent lining material in electric furnaces, metallurgical sintering furnaces, nonferrous metal smelting processes and for nonferrous metal casting operations. Furthermore, its thermal conductivity and impact resistance makes it an invaluable asset.

Sintered alpha silicon carbide’s low thermal expansion properties make it well suited for applications that demand rapid temperature changes, such as blast nozzles. For instance, its use has long-term life (50% more than tungsten carbide), low wear rates and exceptional erosion resistance.

Sic is an excellent material choice for acid spray nozzles and other parts exposed to harsh chemical environments due to its excellent abrasion and corrosion resistance. Hardening with chromium and molybdenum additives may extend its durability; however, this significantly increases material costs. Sic’s low specific weight makes it particularly suitable for applications where space and weight restrictions exist, including rocket motors and composite armor protection systems.
