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:

The finned tube are particularly efficient as the channels are welded on the external surface of the tube by means of resistance weld technique. Every channel is the result of a fin strip shaped into a U-form, such that each leg of the U will form a fin. The number of fins will be always a multiple of four with a maximum number depending on the outside diameter of the tube and on the thermodynamic calculations promoted for a specific job.


Third Part Inspection is acceptable.

Advantages of Longitudinal Finned Tube:

1,The heat transfer area is 8 to 12 times of the bare tube.
2,More effective than bare tubes.
3,As the heat transfer area increases, a smaller size exchanger is required.
4,More economical options.
5,The fins can be cut or twisted to increase fluid turbulence on the shell side and improve heat transfer.

Frequently Asked Questions (FAQ) About Longitudinal Finned Tubes:

 

 

1. What Are Finned Tubes Uses?

Finned tubes are particularly useful in the case of air heat exchangers. In an air heat exchanger, the heat transfer is to take place between a liquid and gas. With the heat coefficient of the air side being lower, a finned tube can be exceptionally helpful. A finned tube increases the surface area and thus helps in faster heat transfer between the components.

 

2. How is fin height calculated?

Length of fin calculator uses Fin length = (Perimeter-(2*Height))/((4*Number of fins)) to calculate the Fin length, The Length of fin formula is defined as the length of the fins required for the effective heat transfer.

 

3. What is a longitudinal finned Tube?

Longitudinal Finned Tube also called Brown Fintube , which produces by high frequency resistance welding fins in the longitudinal direction with the length of the tubes.

 

4. What are properties of longitudinal finned tubes?

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.

 

5. What are applications of longitudinal finned tubes?

We supply longitudinal finned tubes for:

double pipe heat exchangers

multi-tube heat exchangers

fire rated heaters

gas coolers

tank heaters

And we are able to accommodate the requirements of various industries, including oil, power, chemical, and petrochemical.
