Laser welded fin tube

1. Material  

Common materials for laserwelded finned tubes include:  

Stainless Steel (e.g., 304, 316L, 310S): High temperature and corrosion resistance.  

Carbon Steel/LowAlloy Steel (e.g., 20, Q345): Costeffective for industrial heat exchangers.  

NickelBased Alloys (e.g., Inconel 600/625): Extreme temperature resistance for aerospace/nuclear applications.  

Titanium/Alloys: Lightweight and corrosionresistant for marine/medical uses.  

Copper/Alloys: Superior thermal conductivity for precision cooling systems.  

2. Dimensional Specifications  

Base Tube OD: 6–50 mm (customizable)  

Fin Height: 3–15 mm  

Fin Thickness: 0.1–1.0 mm (ultrathin fins supported)  

Fin Spacing: 1–5 mm (highdensity design)  

Tube Length: 0.5–15 m (continuous welding available)  

3. Features  

HighPrecision Welding: Narrow, deep seams with minimal heat distortion.  

Complex Geometry: Compatible with spiral/serrated fins and ultrathin fins (≥0.1 mm).  

Smooth Surface: No slag residue, ideal for clean or highpurity fluids.  

Extreme Tolerance: Operates from 200°C to 800°C, withstands up to 30 MPa pressure.  

4. Advantages  

Long Service Life: Metallurgical bonding resists thermal fatigue and vibration.  

Enhanced Heat Transfer: 40–60% higher efficiency than conventional finned tubes.  

Low Flow Resistance: Smooth seams reduce energy consumption.  

LeakFree: Ideal for hazardous or highpressure fluids.  

5. Applications  

Advanced Industries: Nuclear reactors, spacecraft thermal management, semiconductor tools.  

Energy & Environment: Gas turbine waste heat recovery, hydrogen systems, carbon capture.  

Chemical/Pharmaceutical: Corrosive media heat exchange, sterile pipelines.  

Transportation: EV battery cooling, marine engine radiators.
