Silicon Carbide Tube

Silicon carbide is an incredible tough ceramic material with long lifespans. Capable of withstanding harsh conditions like high temperatures and chemicals, making it suitable for industrial uses such as 3D printing, ballistics production, chemical production and paper manufacturing, among many other applications.

Silicon Carbide (SiC) thermocouple protection tubes feature high flexural strength, thermal shock resistance and corrosion protection properties. Available in an assortment of sizes and shapes to meet application demands.


Silicon carbide, with hardness comparable to diamond, is an extremely durable material. This durability makes silicon carbide ideal for manufacturing machinery that must withstand high temperatures and harsh environments, such as industrial products.

Refractory ceramic is known for its strong wear resistance, corrosive acid resistance, and chemical stability – two attributes that make it popularly used in power plants and heavy industry settings with numerous chemicals and corrosive substances present. For these reasons it has often been chosen for applications involving chemicals or corrosion-inducing substances.

Silicon carbide tubes come in all sorts of shapes and sizes to meet various applications in various industries such as chemical processing, oil drilling and automotive components. Silicon carbide protection tubes are especially popular for protecting thermocouples due to their ability to withstand high temperatures and abrasion. There are three varieties of these protection tubes; oxide bonded, nitride bonded (isopressed), and carbon bonded varieties; each offers different benefits – so before making a purchase decision it is crucial that one understands how each works and works prior to purchasing it.

Corrosion Resistance

Silicon carbide boasts a Mohs hardness rating comparable to diamond, making it a durable material with strong wear resistance and corrosion-resistance, ideal for applications where equipment will be exposed to harsh chemicals and abrasive environments – like spray nozzles, shot blast nozzles, ceramic tubing or cyclone components.

Owing to its excellent thermal conductivity, low thermal expansion rate and resistance against acids, ceramic insulation is often utilized by industrial furnace lining manufacturers to protect equipment against high temperatures and harsh substances in mining operations.

Silicon carbide offers excellent impact resistance and pressure resistance, making it a popular choice for oil drilling tubes and mining and power industries, where extreme temperatures and pressure conditions must be accommodated. Furthermore, silicon carbide has long been utilized in bearings, pump seals, extrusion dies, etc. due to these attributes.

High Thermal Conductivity

Silicon carbide is a material with unparalleled strength, wear resistance, and thermal conductivity properties that makes it suitable for industrial applications in harsh environments and extreme temperatures. Furthermore, silicon carbide’s durability allows it to endure abrasion wear as well as frictional wear – which makes it the ideal material to use in many industrial settings.

This extraordinary ceramic material can withstand even the toughest of environments, boasting impressive chemical and mechanical properties that extend up to 1,400degC. It boasts 50% harder than tungsten carbide with high Young’s modulus and outstanding dimensional stability; plus low thermal expansion rates as well as resistance against acids and lyes.

Saint-Gobain’s Hexol(r) SE sintered SiC is the go-to material for light water reactor (LWR) cladding, with an extensive track record of reliability and durability. This ceramic has excellent steam oxidation resistance, neutron absorption capabilities and strong strength retention after radiation damage, making it suitable for composite armor systems which offer enhanced ballistic capability against current and emerging threats. Furthermore, Hexol SE Sintered SiC offers wide thermal conductivity/diffusivity range depending on matrix/fiber microstructure density/microstructure density/density for maximum effectiveness in LWRs cladding applications.

Long Lifespan

Silicon carbide is an exceptionally hard and durable material, making it the ideal choice for many industrial applications. Thanks to its long lifespan, silicon carbide can withstand extreme temperatures and harsh corrosive environments without degrading or breaking down over time.

These features make the material suitable for various industrial uses, including ceramics, power generation and metallurgy. Furthermore, its light weight makes it easily manageable.

Silicon carbide is a man-made material produced through several steps, from powder preparation and mixing with binders, through shape forming via extrusion (tubes) or cold isostatic pressing (plates and blocks), shape sintering under vacuum at high temperature, to its final stage of sintering under vacuum at extremely high temperatures – the sintering process confers ultimate corrosion resistance, extremely high strength, hardness, mechanical properties and corrosion resistance into its finished product; second only to diamond in terms of hardness – with natural occurring moissanite as natural rival.
