Aluminium vs. Galvanised Iron (GI) Pipes
A detailed comparison of flow efficiency, installation labor, corrosion resistance, and total cost of ownership (TCO) for compressed air systems.
Why Traditional GI Piping Fails in Compressed Air
Galvanized Iron (GI) and carbon steel have historically been used for compressed air due to their low initial material cost. However, they present severe long-term drawbacks in compressed air applications. Moist compressed air causes internal rusting, leading to scaling and corrosion. This roughs the pipe interior, drastically increasing friction loss and clogging downstream filters, valves, and pneumatic tools.
Direct Comparison: SecureAir vs. Galvanised Iron
| Feature | SecureAir Aluminium | Galvanised Iron (GI) |
|---|---|---|
| Internal Corrosion | None. 100% corrosion-resistant. | High. Rusts over time, creating scale. |
| Air Flow & Pressure Drop | Smooth bore. 36% more airflow per bore. | Rough interior. High friction & pressure drop. |
| Installation Time | Fast. Modular push-to-connect fittings. | Slow. Threading, heavy lifting, high labor. |
| System Weight | Lightweight. Easy to mount and support. | Very heavy. Requires heavy-duty brackets. |
| Leakage Rates | Zero leaks. Dual-NBR sealing rings. | High. Threaded joints leak over time. |
Long-Term Return on Investment (ROI)
While GI pipe may have a lower initial purchase price, the total cost of ownership is significantly higher. Compressed air leaks and pressure drops force air compressors to run longer and harder, consuming up to 30% more electricity and increasing maintenance costs. SecureAir's leak-free design and smooth inner walls typically pay for themselves within 12 to 24 months through energy savings alone.
