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.

 

 

 

Longitudinal Finned Tube Product Description:

 

Longitudinal Finned Tube produces by high frequency resistance welding fins in the longitudinal direction with the length of the tubes. Fin strip material shall be compatible with and suitable for standard frequency resistance welding to the specified tube material.Before applying the fins, the tube outside surface shall be properly prepared to ensure that the fin-to-tube weld is sound.The fin strip is first bend into U-shaped channel, so that each leg of the U will be a fin. The channels cut into the suitable length and oriented along the length of the tubes and resistance welded in place. The channels weld in pairs, diametrically opposed -- therefore the number of fins specified always be a multiple.

Longitudinal Finned Tube

Longitudinal Fin Tube Manufacturing Process:

 

Longitudinal Finned Tubes are produced by resistance welding fins in the longitudinal direction along the length of the tube. The fin strip is first formed into a U-shaped channel, such that each leg of the U will form a fin. The channels are cut to the appropriate length and then oriented along the length of the tube and resistance welded in place. The channels are welded in pairs, diametrically opposed- therefore the number of fins specified must always be a multiple of four.

For a given pipe or tube size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height and number of fins. The maximum number of fins is dependent upon the tube outside diameter — larger OD tube can accommodate a greater number of fins.

 

 

Fin Tube

 

 

Longitudinal Fin Tube(Carbon Steel Welded Pipe) Advantages:

1. Longer working life than others ordinary welding helical fin tubes.

2. Much safer and energy saving.

3. Increase the heat transfer rates for viscous liquids.

4. Perforated fin type used whenever drainage of liquid from fin channels become a problem.

5. Longitudinal fin tubes are widely used in horizontal heat exchangers.

 

Welded Steel Pipe

 

 

Brown Fin Tube Properties:

Improve heat transfer efficiency in efficient space.

Reduces installation space on required heat transfer surfaces.

Reduce the cost of the equipment, and have a high operational reliability.

The pressure drop on the side of the tube is reduced and the operation cost is reduced.

The stiffness of steel tube is improved, and the seismic performance of steel tube is improved.

Enhance heat transfer, reduce flow resistance and metal consumption.

 

 

Longitudinal Fin Tube

 

 

Longitudinal Finned Tube(Welded Steel Pipe) Applications:

Longitudinal finned tubes are generally used for petrochemical industry particularly suited to high temperature, high pressure applications with high fin-side temperatures.
