Silicon Carbide Tube – A Marvel in Industrial Engineering

Silicon carbide tube is an amazing feat of industrial engineering, boasting incredible strength and resilience. Not only can it withstand high temperatures and harsh environments like abrasive environments and chemicals, it has an indefinite lifespan as well!

SiC tubes come in oxide-bonded, nitride-bonded and carbon bonded (isopressed) varieties; it’s important to understand their respective features before making your purchase decision.

Pressureless sintered

Silicon carbide is an extremely durable ceramic material, offering exceptional resistance to heat and wear. Due to its inherent strength and durability, silicon carbide tubes are used in demanding applications where most metals or other materials would fail, such as reaction bonding and pressureless sintering processes. These techniques make silicon carbide ideal for tube manufacturing in demanding applications where performance cannot be compromised by compromise with other materials such as most metals and other substances.

Reaction bonded silicon infiltrated with carbon (SISIC) is one of the most widely utilized forms of SiC. It boasts an extremely dense structure free from pores or cracks, and offers exceptional mechanical properties including fracture toughness and high strength. SISIC also exhibits outstanding resistance to acids and alkalis as well as resistance against corrosion by hydrofluoric acid corrosion.

SISIC manufacturing requires filling porous preforms of silicon carbide and carbon with molten silicon, which reacts with carbon to form additional silicon carbide resulting in dense and strong final product. Unlike conventionally sintered SiC that requires complex forming techniques and costly equipment to form into dense shapes and sizes, SISIC production allows for flexible shapes and sizes with lower tool costs than other forms.

As ceramics dissipate an excessively large amount of electricity during sintering, furnace temperatures decrease and energy requirements decrease – these advantages help significantly cut operational expenses while simultaneously producing complex long-length components in less time.

Hexoloy(r) SE

Hexoloy is an engineered ceramics family designed for specific applications. Like other ceramics, Hexoloy can be machined using traditional means; however, its special attributes make it particularly effective under challenging operating conditions. Our engineers are ready to discuss your application with you and offer solutions tailored specifically to meet your requirements.

Hexoloy SE is a sintered silicon carbide ceramic material, one of the hardest high-performance materials on Earth. It is more than 50% harder than its rival tungsten carbide and boasts a density of over 95% theoretical. Due to its extreme hardness, Hexoloy SE provides highly resistant protection from abrasion and impact damage as well as chemical corrosion resistance at high temperatures while still retaining structural integrity.

Hexoloy SE stands out as an outstanding material due to its relatively low absorption of negatively charged organic matter, helping it meet challenging liquid environments with high levels of natural organic matter (NOM). Furthermore, Hexoloy SE boasts very high refractoriness that ensures consistent performance under harsh operating conditions and has shown excellent fracture initiation toughness under fracture-dominated stress states; such characteristics make Hexoloy SE an invaluable choice when crack propagation is slow or difficult to control – conventional AM-DCB tests have also been enhanced in order to accurately measure these characteristics accurately allowing accurate measurement in displacement controlled tests using AM-DCB tests alone.


Silicon carbide is a multifaceted material capable of meeting high-demand applications. It can withstand extreme temperatures, corrosive chemicals, abrasive environments and mechanical strength and longevity requirements, making it perfect for power industry applications.

Silicon carbide offers exceptional chemical resistance and thermal shock resistance, along with low corrosion rate and dimensionally stability – qualities which make it ideal for use in various applications such as sandblasting nozzles, ceramic seals and large wear components for mining operations.

Silicon carbide stands out as an extremely durable and hard material with a Mohs hardness rating of 9; making it ideal for cutting wheels and grinding tools. In addition, silicon carbide can be easily formed into various shapes using pressureless sintered processes which require less energy and are environmentally-friendly; creating parts with tight tolerances, geometric constraints, and easier machining capabilities than any other material available today.

Silicon carbide is known to be both tough and acid-resistant, making it perfect for use in power industry applications like coal chemical industries and transportation pipelines. Furthermore, this material excels as an option in metallurgy applications, such as steel plant slag flushing trenches. Furthermore, RB SiC can easily be formed into various shapes such as cylinders, bellows, and flanges for further use within various industries.

Thermocouple protection

Silicon carbide is an innovative material with many applications in industrial settings. Thanks to its superior mechanical strength, thermal conductivity, corrosion resistance and long lifespan and excellent durability characteristics, this high-performing material offers many advantages that can reduce maintenance costs while increasing productivity.

Thermocouple protection tubes are ceramic sheaths for thermocouples that provide high temperature resistance. Available with various tube diameters and lengths, they can withstand temperatures up to 1000 degC without being subject to thermal shock or erosion. Made from corrosion-proof refractory material resistant to spalling and erosion, thermocouple protection tubes should be considered an efficient choice in applications requiring high refractory standards and performance under high temperature environments. Pyrosales advocates using them in applications requiring both quality refractory standards and performance – highly recommended by Pyrosales!

A tube is placed between hot gas and thermocouple wire to reduce heat transfer between them and reduce variation in bead temperature profile. Furthermore, it acts as a barrier between incoming and outgoing gases by preventing condensation or radiation. To determine its impact on bead temperature profile results can be compared with and without it.
