Introduction
Laser-welded titanium finned tubes are titanium-based laser-welded finned tubes used in high-efficiency heat exchange equipment. They are suitable for highly corrosive and high-intensity working conditions such as seawater desalination, chemical heat exchangers, and waste heat recovery.
Advantages
High heat exchange efficiency
Laser welding creates a 100% metallurgical bond between the fins and the base tube, reducing thermal resistance and making heat transfer more efficient.
Corrosion resistant
The tube body is made of industrial-grade titanium (such as Gr2), which naturally possesses excellent resistance to seawater and chloride ions.
Fins do not detach
Laser welding creates continuous welds with a weld strength reaching 80-90% of the base material, capable of withstanding temperature fluctuations and vibrations.
Manufacturing process
1. Laser Welding Process
Fully automated laser welding equipment is used to continuously weld fins to titanium tubes.
2. Production Steps
Titanium Tube Pretreatment: Degreasing, Activation → Improves weld cleanliness and strength
Fin Forming: Precise Dimensions → Ensures weld uniformity
Continuous Laser Welding: Metallurgical Bonding → High Thermal Conductivity, No Fin Delamination
Inspection and Calibration: Eddy Current/Dimensional Inspection → Stable and Reliable
Protective Treatment: Port Protection → Prevents Transportation Damage
Packaging and Transportation
Moisture-proof film + end caps + wooden crate/steel frame for secure packaging to prevent fin damage and surface scratches; supports sea, air and multimodal transport.
