Product Description

Enhanced Performance Wound Finned Tubes

Base Tube: ASTM A179 Carbon Steel | Fin Material: AL1060 Aluminum Alloy

1. Material Synergy: A179 + AL1060

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.

2. Precision Manufacturing Process

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

5. Industrial Applications

Heat Recovery Systems: Preheats air in boilers (up to 30% efficiency gain).

Petrochemical: Condensers in refineries (resists H₂S corrosion).

Power Generation: Economizers for coal/gas plants.

HVAC: High-efficiency air coolers for data centers.

Marine: Dehumidifiers in ship engines.

6. Competitive Advantages

Extended Lifespan: AL1060 fins protect A179 base from oxidation.

Energy Savings: 40% higher heat flux vs. stainless steel finned tubes.

Custom Engineering: Optimize fin pitch/density for specific media (steam, flue gas, oil).

Certified Quality: ISO 9001, ASME B31.1, RoHS compliant.

7. Proven Expertise

With 15+ years in thermal solutions, we’ve supplied 50,000+ tubes for projects in 22 countries. Case study: Installed in a German biomass plant (2023), reducing fouling by 70% vs. extruded fin tubes.
