Laser welded finned tubes are the most technologically advanced products with irreplaceable advantages
1. The thickness of the base tube can be 0.8-1.5mm, and the thickness of the fin can be 0.3-1mm, which greatly saves the material cost compared with other processes.
2. High penetration rate, can prevent crevice corrosion, prolong service life and reduce heat transfer resistance.
3. It is easy for secondary processing, and can be directly coiled and bent.
4. Breaking through the material limitation, different materials can be used for processing.
