Laser Welded Fin Tube Manufacturer and Suppliers in China
Laser welding fin tube is a high-efficiency heat exchange element that tightly connects the fin and the base tube through laser welding technology. It is mainly used in the industrial field to improve the heat exchange efficiency.
How to produce laser welded finned tube?
Laser welded finned tubes use laser beam focusing to melt local metal to form welds, ensuring a tight connection between the fins and the base tube, reducing thermal resistance and improving heat exchange efficiency.
Quality Control for Laser Welded Fin Tube
The quality of the laser welded finned tube is assured by hydrostatic or pneumatic testing, eddy current testing and tensile testing to verify the mechanical bond between the inner tube and the outer fins
Delivery condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with Anti-rust at both ends of laser welded finned tube.

Laser Welded Fin Tube By Application
Top Features of Laser Welding Fin Tube
Datang offers the widest variety of sizes available for Laser welding fin tube in the industry.Its heat exchange efficiency can reach several times or even dozens of times that of ordinary heat exchangers.
1. Due to the fast welding speed and strong self-cooling effect of the weldment, not only the heat affected zone is small, but also oxidation is not easy to occur, so the structure and performance of the weld are very good.
2. Anti-corrosion performance, wear-resistant performance, low contact thermal resistance, high stability, and anti-fouling ability.
3. Large heat exchange area.

Difference Between High Frequency Welded Fin Tubes and Laser Welded Fin Tubes
High frequency welded fin tubes: The manufacturing process is complex, high frequency welding equipment is required, and the cost is high, but the welding is firm and not easy to loosen.
Laser Welded Fin Tubes: High penetration rate can prevent crevice corrosion, extend service life, reduce heat transfer resistance, increase the contact area between fin and base tube, lower contact thermal resistance, and improve heat transfer efficiency by 1.5-2.5 times that of ordinary fin tubes.

Laser Welded Fin Tube Application
The spiral fin tube radiator for vegetable and flower greenhouse is an efficient and durable heating equipment, especially suitable for greenhouse cultivation in cold seasons.
During the breeding and brooding process, the laser welding fin tube radiator improves the heat exchange efficiency by increasing the heat dissipation area, and can raise the temperature in the brooding house to the required level in a short time. This design enables the farm to quickly reach and maintain a suitable temperature range (15-20 degrees Celsius) when heating in winter.
The laser welding fin tube heat exchanger for wood drying is a highly efficient heat dissipation device, which is mainly used to provide a stable heat source during the wood drying process to ensure that the wood is evenly heated during the drying process to avoid deformation and cracking.
The stainless steel finned tube radiator for food drying is an efficient, safe and easy-to-use equipment, especially suitable for the field of food drying.
The working principle of the high-frequency welded finned tube heat exchanger for flue gas waste heat recovery is based on heat conduction and convection heat transfer. High-temperature flue gas passes through the outside of the finned tube, while the working medium (such as water or heat transfer oil) flows inside the tube. The heat of the flue gas is transferred to the working medium through the metal wall of the finned tube, realizing the recovery and utilization of heat energy.
Laser welded finned tube heat exchanger for air preheater is an efficient and durable heat exchange equipment, widely used in various industrial fields.
