Excellent mechanical properties: high hardness (Mohs hardness 9.2-9.6), high strength (bending strength 400-600MPa) and high elastic modulus (400-450GPa).
High temperature resistance: It can maintain structural stability under an inert atmosphere of 1200°C and withstand high temperatures above 2000°C in a short period of time.
Chemical stability: chemically inert to strong corrosive media such as concentrated sulfuric acid, aqua regia, hydrofluoric acid (except), molten salt, etc.
Thermal properties: low thermal expansion coefficient (4.5×10⁻⁶/℃) and high thermal conductivity (120-270 W/(m·K)).
Lightweight: The density is only 1/3 of metal pipes, reducing system load.

Product introduction of silicon carbide ceramic pipe sleeves:
Silicon carbide ceramic pipe sleeves are tubular or sleeve-shaped ceramic products made from high-purity silicon carbide (SiC) powder through molding and sintering processes. Its main features include high hardness, high wear resistance, high temperature resistance and corrosion resistance. It is suitable for high temperature, high pressure and highly corrosive working conditions.

Application fields.
1. Chemical industry: used in strong acid and alkali environments, such as hydrofluoric acid cooling systems (life extended from 2 years to 12 years).
2. Energy field: high-temperature furnace, hydrogen energy system (pressure-resistant 70MPa silicon carbide composite tube can enable hydrogen fuel cell vehicles to exceed 800 kilometers).
3. Electronics and semiconductors: 5G base station radio frequency devices (dielectric loss only 0.0002), semiconductor manufacturing equipment.
4. Aerospace: Rocket engine thrust chamber cooling pipeline components.
5. Metallurgical industry: continuous annealing furnace radiant tube (furnace temperature uniformity increased from ±15°C to ±5°C).
