Excellent Corrosion Resistance Alumina Ceramic Pipe for Industrial Applications

﹡Product Overview

Our high-purity alumina (Al₂O₃) ceramic pipes are engineered for extreme corrosion resistance, thermal stability, and mechanical strength in harsh industrial environments. Custom diameters, lengths, and configurations available for OEM applications.

﹡Key Technical Specifications

✅ Material: 99.5% Alumina (Al₂O₃) – Ultra-low porosity (<0.5%)

✅ Density: 3.9 g/cm³ – Gas-tight structure

✅ Flexural Strength: 350 MPa – Withstands high mechanical stress

✅ Hardness: 1,500 HV (Mohs 9) – Superior abrasion resistance

✅ Max Temperature: 1,600°C (2,912°F) continuous use

✅ Thermal Shock Resistance: ΔT >500°C (Water quenching test)

✅ Chemical Resistance: Impervious to acids/alkalis (except HF & hot H₃PO₄)

✅ Surface Finish: Polished (Ra <0.1µm) or as-fired (Ra 0.5µm)

✅ Standard Sizes:

Outer Diameter (OD): 10–200mm (±0.1mm tolerance)

Inner Diameter (ID): 5–180mm

Length: 50–1,000mm (custom lengths up to 2,000mm)

﹡Industry Applications

1. Chemical Processing

Acid transfer pipes for HCl/H₂SO₄ – 10× lifespan vs. stainless steel

Reactor liners – Resists corrosive slurries at 80°C+

2. Semiconductor Manufacturing

Plasma etch chamber components – Non-contaminating, RF-transparent

Ultra-pure water delivery systems – Zero ion leaching

3. Mining & Mineral Processing

Slurry transport pipes – Withstands abrasive alumina/silica particles

4. Energy & Environmental

Flue gas desulfurization (FGD) ducts – Sulfuric acid resistance

Solid oxide fuel cell (SOFC) stacks – High-temperature insulation

5. Medical & Food

Sterilizable fluid conduits – Biocompatible (ISO 6474)

Pharmaceutical processing tubes – FDA-compliant material

﹡Why Choose Alumina Pipes?

✔ Zero Corrosion – Eliminates rust/pitting in chemical environments

✔ Precision Machining – ID/OD concentricity <0.05mm

✔ Custom Designs – Flanged, threaded, or tapered ends

✔ Cost Savings – 5–8 year service life in abrasive applications

﹡Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
