DELLOK Finned Tube Cross Flow Heat Exchanger

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 description

^{A finned tube is a kind of heat exchange element. It is a kind of Heat Exchanger tube to improve the heat transfer efficiency, usually by adding fins on the surface of the heat exchanger tube to increase the external surface area (or internal surface area) of the heat exchanger tube, so as to achieve the purpose of improving the heat transfer efficiency.}

^{In the compromise of offering to our clients the best possible product with the higher performance for its function, we have the possibility of manufacturing finned tubes by laser welding for increased efficiency and higher quality.}

^{Our Laser Finning Process allows a wider dimensional range of tube and fin combinations. Feasible height, thickness and pitch of fins go way beyond any conventional finning process.}

^{In addition, an increased range of material combinations of both tube and fin (steel, aluminum, copper, titanium) offers new advantages and alternatives to the industry.}

^{Lower energy consumption, reduced cost of consumables and increased efficiency of the process allow us to offer very competitive prices.}

Laser Finned Tube For Condenser

^{Heat Exchanger}

^{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.}

^{· Highest quality product}

^{· Wider range of products in both geometry and materials}

^{· Price saving}

^{The perfect bond between fin and tube improves efficiency in heat transfer and resistance to corrosion resulting in a clean weld fin to tube joint and fully straight fins (no corrugation).}
