About Us
Dellok(YONGHUI Radiating Pipe Manufacturing Co.,Ltd) was established in 2002, which is located in Nanjing, China.We joined HARBIN AIR CONDITIONING CO., LTD. in 2022 and became the most professional industry manufacturer in China. After many years of development, the company now has 66 million yuan in fixed assets, more than 200 employees, and 33 technical staffs. We have 4 aluminum processing production lines, with the annual processing capacity of more than 20,000 tons; And we have 5 tube-drawing production lines; 47 fintube production lines, 1 imported production line from American with the brand of McElroy , with the annual production capacity of 12 million meters the above.
Quality is the theme of eternal pursuit of winner.
Laser Welded Finned Tube Product Description:
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.
Weld spatter is almost completely avoided by the Fin Tube laser welding process, with the advantage that the risk of fouling of the finned tubes is minimized.
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 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).
