Introduction
Laser-welded stainless steel finned tubes are used in high-temperature, high-corrosion, and high-efficiency heat exchange systems, suitable for industrial applications such as chemical engineering, boiler waste heat recovery, and energy equipment.
Features
High Heat Exchange Efficiency
Laser welding achieves a metallurgical bond between the fins and the tube body, resulting in a continuous heat conduction path, lower thermal resistance, and high heat exchange efficiency.
Strong Corrosion Resistance
Made of 304/316L stainless steel, offering stable resistance to acids, alkalis, and oxidation.
Firm and Non-detachable Fins
Continuous laser welds achieve a strength of 80-90% of the base material, capable of withstanding thermal cycling and vibration without loosening or detachment.
Manufacturing Process
1. Laser Welding Process
Automated laser welding is used to achieve continuous fin welding, resulting in narrow welds, minimal deformation, and a strong bond, improving thermal conductivity and durability.
2. Production Flow
Surface Treatment: Degreasing and activation → Enhancing weld strength
Fin Forming: Precise dimensions → Uniform welding
Continuous Laser Welding: Metallurgical bonding → No fin detachment, good thermal conductivity
Inspection and Stress Treatment: Ensuring stability
Port Protection: Preventing deformation during transportation
Packaging and Transportation
Packaging Method: Moisture-proof film + port protection caps + wooden crate/steel frame for securing, preventing fin damage and surface scratches.
Transportation Method: Supports sea freight, air freight, and multimodal transport; large quantities are secured with wooden crates for greater stability; urgent orders can be shipped by air.
FAQ
Q: What industries are suitable for Laser Welded Stainless Finned Tubes?
A: They are widely used in fields requiring efficient heat exchange, such as the chemical, petrochemical, power, air conditioning, and refrigeration industries.
Q: What are the advantages of laser welding for joining fins to tubes?
A: The deep weld depth eliminates gaps in the contact surface, ensuring a continuous heat transfer path and improving heat transfer efficiency.
Q: Will the fins deform or loosen over time?
A: The laser welded structure is stable, the fins are firmly fixed, and they are fatigue-resistant and less prone to deformation.
Q: Is cleaning and maintenance difficult?
A: The smooth surface reduces dust accumulation, making cleaning easy and maintenance cost-effective.
