Conical silicon carbide ceramic tube

   Conical silicon carbide ceramic tubes (SiC conical tubes) are made of silicon carbide (SiC) ceramics into conical/truncated conical tubes that are larger at the top and smaller at the bottom (or larger at one end and smaller at the other). They are high-performance ceramic structural components that are wear-resistant, high-temperature resistant, and corrosion-resistant, and are often used in cyclone separators, high-temperature wear-resistant pipelines, and material feeding/flow guiding components.

Material: High-purity silicon carbide (SiC) powder, formed by pressureless sintering/reaction sintering, resulting in a dense structure with virtually no pores.

Shape: Conical (frustum conical), with different diameters at both ends; available in straight cone, flanged, and straight pipe sections.

Appearance: Dark gray, dense and smooth, with high hardness (Mohs hardness approximately 9.2–9.5, second only to diamond).

Ultra-high wear resistance: Extremely high hardness, resistant to particle erosion, and a lifespan more than 10 times that of steel pipes and more than 3 times that of ordinary ceramics.

High temperature resistance: Melting point approximately 2700℃, capable of long-term operation at extremely high temperatures above 1600℃ without deformation or softening, and able to withstand drastic temperature changes without cracking.

Corrosion resistance: Resistant to strong acids, strong alkalis, and molten metals (such as molten aluminum), exhibiting strong chemical stability.

Thermal shock resistance: Low thermal expansion and good thermal conductivity, preventing cracking under rapid heating and cooling.

High strength and low weight: High specific strength, with a density approximately half that of steel, making it impact-resistant and not easily broken.

The conical structure (wide at one end and narrow at the other) is mainly designed based on the needs of fluid mechanics. When a liquid or gas carrying solid particles flows through a conical tube, the continuous reduction in the tube diameter forces the fluid velocity to increase and the pressure to change, thereby generating a strong swirling (vortex) centrifugal force.

Due to their unique shape and material, conical silicon carbide ceramic tubes are most commonly used as core linings or components in the following equipment:

Hydrocyclones (most common application):In mining and coal washing, hydrocyclones utilize centrifugal force to separate coarse and fine particles in slurry. The conical section is the area most severely worn; using silicon carbide conical tubes can significantly extend equipment life.

Desulfurization and Dust Removal Systems:In thermal power plants or large-scale environmental protection equipment, they are used as nozzles or the lower cone of cyclone dust collectors to resist the scouring of high-speed airflows containing sulfur dioxide and hard fly ash.

High-Temperature Wear-Resistant Piping:High-temperature dust/particle conveying pipes, feed pipes, and flue gas reduction sections in metallurgy, coking, and power plants.

Kilns/Thermal Equipment:Kiln discharge cones, guide pipes, and burner sleeves in the ceramics and refractory materials industries.

New Energy (Lithium Battery Materials) Industry:In the pneumatic conveying and classification of positive and negative electrode material powders, not only is extremely high wear resistance required, but also strict "zero metal contamination" is demanded. Silicon carbide ceramic tubes are not only

wear-resistant but also prevent metallic impurities from contaminating battery materials.

Pipe diameter transition sections: In chemical and metallurgical powder or slurry conveying pipelines, these serve as transition joints (reducers) where the pipe diameter decreases from a large diameter to a small diameter, preventing severe wear caused by sudden changes in flow velocity.
