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.


Product Introduction:


1, Laser welded finned tubes are processed fully automatically by a high precision laser welding machine.
Laser Welded Finned Tube adopts the leading processing technology by irradiating a high intensity laser beam to the metal surface, through the interaction of laser and metal, the metal absorbs the laser and converts it into heat, which melts the metal, forms cooling crystals and firmly welds the fins to the tube.
3, Laser welded finned tubes have a fully automatic welding process, saving labor costs; secondly, laser welded fins are firm, high strength and tested for tensile strength. The efficiency of laser welding is higher.

Advantages of laser welding finned tube

1. The laser welding finned tube fin machine has a high degree of automation, and the welding of the fin to the
tube and the winding of the tube are synchronized
2. 100% welding rate, laser welding finned tube and fins are strong, the welding strength exceeds 600MPa.
3. The precision of laser welding tube finishing machine is up to 0.05mm
4. 0 contact resistance, achieve high efficiency of heat transfer of spiral finned tube by laser welding.
5. Save production costs. The laser welding finned tube has a smaller fin spacing, less than 2.5mm. Compared with
the high frequency welded spiral finned tube, the heat transfer area is increased by about 50%, which makes the
material cost Reduced, volume reduced
Heat Exchanger.
6. The advantages over conventional MAG / HF welding are of decisive importance. The complete connection between the fin and the
base tube brings excellent heat transfer, and the thermal performance of the
Fin Tube is increased by 2.5 times. Continuous
welding prevents the notch effect, thereby avoiding the formation of v-corrosion and cracks under the condition that the
finned tube may swing. The heating of base metals during welding is low and the travel speed is up to 20m / min. Minimize the
heat affected zone in the base tube. Therefore, it does not include the complete melting of the tube and the related
metallurgical transformation of the parent metal.
