Alumina Ceramic Lined Tees and Lined Pipe Fittings

Alumina ceramic tee is a T- or Y-shaped pipe connector made from high-purity alumina (typically 95% Al₂O₃) ceramic. Its primary function is to divert (dividing one inlet into two outlets) or merge (merging two inlets into one outlet) fluids within a piping system. Because it is entirely or lined with alumina ceramic, it is particularly adept at handling fluids containing high-velocity solid particles, powders, or corrosive media.

Alumina ceramic tees are essential specialty fittings in harsh industrial environments. Leveraging the exceptional performance of alumina ceramic, they play a key role in severe abrasive and corrosive conditions requiring diversion or merging.

1. Extreme Wear Resistance (Core Advantage):
When media flows through ceramic tees, especially in the impact zone at the diversion point, they experience severe erosion and wear. The ultra-high hardness of alumina ceramic (HRA ≥ 85) effectively resists this wear, resulting in a lifespan dozens or even hundreds of times longer than that of ordinary steel tees.

2. Excellent Corrosion Resistance:
Alumina ceramic tees are resistant to corrosion by most acids, alkalis, salts, and organic solvents (except hydrofluoric acid and hot concentrated alkali), making them suitable for corrosive environments such as the chemical and metallurgical industries.

3. High-Temperature Resistance:
Alumina ceramic tees can operate stably and for extended periods at temperatures exceeding 1600°C without deformation or oxidation, making them suitable for piping systems handling high-temperature flue gas and hot air.

4. Smooth Inner Surface:
The smooth ceramic surface of alumina ceramic tees offers a low coefficient of friction, effectively reducing fluid resistance and preventing material sticking and clogging.

Alumina ceramic tees are life-saving components in the following high-wear industries:

1. Power Industry (Coal-fired Power Plants):

• Fly ash pneumatic conveying systems: Used for diverting and switching ash silo feed and ash conveying pipelines.
• Slag removal systems: Used for bottom ash conveying pipelines.
• Desulfurization (FGD) systems: Conveying and distributing limestone or gypsum slurries.

2. Mining and ore dressing plants:

• Conveying and distributing ore fines, tailings, and concentrate powder.
• Diverting heavy medium suspensions.

3. Cement industry:

• Pneumatic conveying of raw meal powder, coal powder, and cement clinker powder.

4. Chemical industry:

• Conveying, diverting, and combining materials containing solid catalysts.
• Handling corrosive and abrasive slurries.

5. Iron and steel:

• Pipelines for blast furnace pulverized coal injection systems and dust removal systems.
