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:

The Extruded Fin Tube also known as Bimetallic Fin Tube is one of the most preferred finning processes for various applications.

The fins are manufactured by Extruding the Fins on the Aluminum Muff Tube which is made to Fit with close tolerance over the Base Tube.

The Extrusion takes place on a Continuous Fin Extruder with Three Tooling rolls and extrusion takes place at high pressures in the range of 1200 psi.

Because of the cold working process the Bond between the Tube and fin is flawless and hence gives excellent Heat Transfer Efficiency.

At the same time the mechanical strength of the fins is also enhanced drastically.

          Aluminum Extruded Tubing


         Manufacturing Process:

          A carefully degreased core tube is fitted into an aluminium primary tube.

         This assembly is then fed into the triple-spindle finning head of the fin-extruding machine.

         Three special multi-disc packs extrude the aluminium tube into helical high fins

         while reducing the inner diameter to give firm pressure contact with the core tube

         Fin materials: Aluminium

         Base tube materials: Any metallic material


          Extruded Aluminum Tube



         1) Thermal

         The bonding of the outer and inner tubes removes the risk of loss of contact

         with the aluminium due to thermal stress.

         Maximum operating temperature: 250°C. The transfer coeffcient remains steady.

         Additionally as the outer sleeve is continuous no electrolytic couple is created.

         2) Mechanical

         The fins are more rigid and stand the handling shocks better,compared to types "G" an "L".


          Extruded Aluminum Tubing



        To improve the heat transfer efficiency in the effective space.

        To Reduce the required installation space for the required heat transfer surfaces.

        To lower equipment cost while having higher operational reliability.

        The running cost is lowered due to lower tube side pressure drop.

        The rigidity of tube is increased, which improves the seismic resistance of the tube.

        Enhancement of heat transfer, reduction on flow resistance and metal consumption.


         Extruded Fin Tube



       These Fin Tubes find application in AIR FIN COOLERS, DRIERS, RADIATORS etc and are preferred

       in Industries like Food

       and Agriculture, Power Plants, Chemical Industries, Steel Plants, Chiller Plants etc.
