What Are Insulated Aluminium Tubes?
Insulated aluminium tubes are lightweight, corrosion-resistant pipes used in HVAC and refrigeration systems. They consist of seamless aluminium tubing wrapped in polyethylene (PE) foam or rubber insulation to prevent heat transfer and condensation.
Why Aluminium?
- Lightweight: 60% lighter than copper, reducing installation labor and costs.
- Cost-Effective: 30–50% cheaper than copper tubes.
- Corrosion Resistance: Natural oxide layer protects against humidity and salt (ideal for coastal Libya).
Key Components:
- Aluminium Core: 1070 or 6063 alloy (ASTM B209/EN 573).
- Insulation Layer: PE foam (thermal conductivity: 0.0402 W/m·K) or rubber.
- UV-Resistant Jacket: Protects against North Africa’s harsh sunlight.
Technical Specifications & Standards

| Feature | EN 12735-1 (EU) | ASTM B209 (USA) |
|---|---|---|
| Material | Aluminium 1070 | Aluminium 6063 |
| Wall Thickness | ±10% tolerance | ±5% tolerance |
| Testing | Tensile + elongation | Eddy current + pressure |
| Best For | Industrial HVAC | Residential AC |
Why EN 12735-1?
Benro Industries’ aluminium tubes meet EN 12735-1 standards, ensuring durability in Algeria’s desert heat and Tunisia’s humid climates.
Applications of Insulated Aluminium Tubes
1. Residential Air Conditioning
- Split AC Systems: Pre-insulated tubes for connecting indoor/outdoor units.

- Solar HVAC: Compatible with renewable energy systems.
3. Automotive & Aerospace
- Cooling Lines: Lightweight tubes for electric vehicle battery cooling.
5 Benefits of Insulated Aluminium Tubes
- Energy Efficiency: PE foam reduces heat gain by 40% (ASHRAE Study).
- Easy Installation: Flexible coils cut labor time by 30%.
- Eco-Friendly: Recyclable materials align with Algeria’s sustainability goals.
- Low Maintenance: Resists corrosion and UV damage.
- Cost Savings: Affordable alternative to copper without sacrificing performance.
How to Choose the Right Insulated Aluminium Tube
Step 1: Determine Tube Size
| AC Capacity (BTU) | Liquid Line (mm) | Suction Line (mm) |
|---|---|---|
| 9,000–18,000 | 6.35 | 9.52 |
| 24,000–48,000 | 9.52 | 12.7 |
Step 2: Select Insulation Type
- PE Foam: Ideal for indoor HVAC (R-value: 3.3).
- Rubber: Better flexibility for tight spaces.
Step 3: Verify Certifications
- Look for EN 12735-1 or ASTM B209 compliance.
- Ensure fire ratings (e.g., ASTM E84 Class 1).
Installation Best Practices
- Avoid Bends: Use tube benders to prevent kinks.
- Seal Joints: Apply UV-resistant tape at connections.
- Test for Leaks: Pressure-test with nitrogen before charging refrigerant.
Pro Tip: Benro’s pre-insulated tubes come with pre-attached flare nuts (قطع غيار تكييف) for faster installation.
