DELLOK Laser Welded Copper Fin Tube



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:


1.Thin and continuous ideal seams

2.Small heat affected area

3.Slightly discolored welding parts

4.The tubes and fins have only slight microstructure changes

5.High heat forms seams

6.Since the high welding integrity between the tube and the fins is avoided, the crevice corrosion is avoided, thereby improving safety

7.Laser welding is carried out in a protective atmosphere, so the weld is free of impurities


Laser Welded Finned Tube


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.


DELLOK Laser Welded Copper Fin Tube 1


Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:


1.The thickness of base tube and fin can be 0.8-1.5 mm and 0.3-1 mm respectively, which greatly saves the material cost compared with other processes.

2.High penetration rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance.

3.No material restriction, different materials can be used for processing.

4.Easy for secondary processing, can be directly coiled and bent.

5.The welding heat affected zone and the metallographic change are small, which makes it possible to process the small diameter finned tube.

6.A variety of material combinations are available, titanium/ copper, titanium/titanium, carbon steel/carbon steel, stainless steel/stainless steel, stainless steel/copper, etc.


Spiral Welding Pipe


Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:

1.Advanced technology: the product using laser welding technology, 100% penetration rate.

2.Stable quality: the equipment using full automatic production process, product quality is stable and reliable.

3.High heat efficiency: the product has smaller fin spacing and thin tubes to increase the heat transfer area and heat transfer rate.

4.It can be bent into different shapes to meet different production needs.
