Laser Welded Finned Tube Product Description:
We produce laser welded finned tubes . And it is widely used for civil wall-hung boilers, industrial boilers, etc. By comparison, the laser-welded finned tube is the most advanced product of irreplaceable advantages. It has a high penetration rate, can prevent crevice corrosion, prolong service life and reduce heat transfer resistance. Breaking through material restrictions. And it can use different materials for processing, saving material costs, and easy for secondary processing.
The disadvantage of laser welding is that the processing time is longer and the output will be limited.
Laser Welding Fin Tube Manufacturing Process:
The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using advanced laser welding technique.
Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:
The advantages over conventional MAG/HF welding are of decisive importance.
The complete connection between the fins and the base tube brings about excellent heat transfer and up to 2.5 times higher thermal performance of the finned tubes.
The continuous weld prevents notch effects and v Corrosion and the formation of cracks are hence avoided also in the case of possibly oscillating finned tubes.
The low base metal heating during welding and the high speed of travel of up to 20m/min. Minimize the heat-affected zone in the base tube. Complete melting of the tube and a related metallurgical transformation of the parent metals are hence excluded.
Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:
100% welding between fin and base tube without using any filler material.
The laser welding process is carried out under the protective atmosphere, and no impurity of the weld seam.
Laser Welded Finned Tube(Stainless Steel Welded Pipe) Applications：
The fin tubes are mainly used in heating (gas-fired boilers, condensing boilers, flue gas condensers), in mechanical and automotive engineering (oil coolers, mine coolers, air coolers for diesel engines), in chemical engineering (gas coolers and heater, process cooler), in power plants (air cooler, cooling tower), and in nuclear engineering (uranium enrichment plants).
