DELLOK Aluminum Boiler Laser Welded Radiator Finned Tubes



About Us


DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) was established in 2002, which is located in Jiangsu, 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 -Production workshop- Meticulous works, standardized management system and systematic quality assurance are Dellok(YONGHUI)'s best commitment to quality. In Dellok(YONGHUI), the quality control is not only the detection of the final process, but throughout the entire production process. We implement a set of quality control and assurance systems. Each batch of pipes is sampled and tested, and records are kept as a quality guarantee for the final product.



Laser Welded Finned Tube Product Description:

Murphy produces finned tubes by laser welding for increased efficiency and higher quality.

The fins (solid or serrated) are helically wound and continuously welded to the tube by a fully automatic laser finning machine. This new laser finning process produces a perfect fin-to-tube bond with lower heat input and improved efficiency in heat flow and resistance to corrosion.




Laser Welding Fin Tube Manufacturing Process:

Laser welding is a high intensity laser beam to the metal surface, through the interaction of laser and metal, metal absorption laser into heat to make the metal melt after the formation of cooling crystallization welding.

Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:

Laser welded finned tubes (fin tubes) finning machine has high automatic, the welding of fin to tubes and winding on tubes are made synchronously.

100% welding rate, Laser welded fin tubes has strong soundness between fins and tubes, welding strength is over 600MPa.

Laser welded tube finning machine has high precision up to 0.05mm.

0 contact resistance, high co-efficiency of heat transfer for spiral fin tubes by laser welding.

Save production cost. Laser welded finned tubes (fin tubes) has more small fin pitch, less than 2.5mm, its heat transfer area increase around 50% comparing to high frequency welded helical (spiral) finned tubes, which make material costs decrease largely as well as volume of Heat Exchanger.

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.
