DELLOK High Frequency Welded Carbon Steel Spiral 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.}

The Laser Welded Finned Tube broadens the Fin Tube family, giving us more choices of fin tubes.

Application of Spiral Fin Tubes:

Waste heat boiler tube;
Economizer tube;
Power station boiler tube;
Marine boiler tube;
Heat Exchanger

Benefits of laser welded fin tubes

^{Laser welded fin tube can avoid gap corrosion and have a longer service life}

^{–Easy to clean and disinfect, the laser fins meet the requirements of the food and pharmaceutical industry}

^{-Optimum heat transfer, reduced materials, reduced footprint of heat exchanger and lower investment costs}

^{-Compliance with process flow, reduce downtime, reduce operation and maintenance cost, investment cost}

^{-The laser welded fin tube can be bent in the fin part, fast and easily processed, reducing the bypass flow.}

^{-The tube is almost unaffected by the welding process, with a possible smaller tube wall, reduced footprint and weight of the fin tube heat exchanger, and reduced manufacturing complexity.}

Laser-welded fin tube

^{Fin type: laser welded fin tube}

^{Base pipe material: steel, aluminum, copper, titanium, etc}

^{Heat material: copper, aluminum}

^{Wender tube length: unlimited}

^{Product Description: 100% welded between fin and tube without filling material.The laser welding in the weld.}

^{100% welding between fin and tube without use of filling material.There are no impurities on the weld for laser welding in a protective atmosphere.Different material of the fins and tubes.Simple bending and coiling of the fin tube.Since the heat-affected areas and welds are small, the material does not deform, while the tubes and fins have only slight microstructural changes.}
