Base Tube: ASTM A179 Carbon Steel | Fin Material: AL1060 Aluminum Alloy
Our finned tubes combine ASTM A179’s thermal conductivity (thermal conductivity: 52 W/m·K) with AL1060’s corrosion resistance. The helical wound design increases heat transfer area by 8–12× vs. bare tubes, ideal for harsh industrial environments.
| Step | Method | Quality Control |
|---|---|---|
| Base Tube Preparation | Cold-drawn, stress-relieved | Eddy current testing |
| Fin Winding | CNC helical winding | Laser-measured pitch accuracy ±0.1mm |
| Bonding | Hydraulic expansion | 100% bond strength testing |
| Surface Treatment | Anodized (AL1060) | Salt spray resistance >1,000 hrs |
Ensures Corrosion Resistance & Thermal Efficiency
