Lord Fin Tube-Laser welding finned tube

The laser welded finned tubes are used in the gas and natural gas wall hanging furnace of the semicarbon boiler, heating furnace, etc. The advantage is that the contact thermal conductivity is zero. Compared with high-frequency welding, the laser welded finned tubes have the characteristics of large fin ratio, light net weight, compact capacity of the assembled heat exchanger, lower carbon and environmental protection, and meet the requirements of energy conservation and emission reduction in China.

Laser welded finned tube is a more professional product with irreplaceable advantages

1: The wall thickness of laser welded finned tube base tube can be 0.8-1.5 mm, and the fin thickness can be 0.3-1 mm. Compared with other processing processes, the cost of raw materials is greatly saved.

2: Laser welded finned tube has high penetration rate, which can prevent gap corrosion, improve service life and reduce thermal conductivity.

3: Laser welding of finned tubes increases the limit of raw materials, and different raw materials can be used for processing.

4: The laser welded finned tube is convenient for secondary processing, and can be used for processing coils and elbows.

5: Laser welded finned tube arc welding has small thermal damage zone and little change in metallographic inspection, which makes it possible to promote the processing of small tubes through finned tubes.

The materials used for heat exchanger tubes and condensers should have excellent thermal conductivity, good corrosion resistance, cleaning resistance, wear and corrosion resistance, and high tensile strength, bending strain and plasticity to facilitate processing, production and processing.
