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:


Fin Tubes are fully integrated so that the Heat Transfer, performance, life and resistance to vibration are excellent. Fin Tubes can improve the thermal performance of a Heat Exchanger without changing in Shell size, Flow Arrangement and Repositioning of tubing. Integral Low Fin Tubes have a very large Heat Transfer ratio thus it is possible to reduce the volume, weight of the Heat Exchangers and finally reduce thecost.




Manufacturing Process


Low fin (integral) tube is an extruded tube consisting of short low fins, the fins are rolled out from the outer wall of the plain tube by rollers, and the tube and fins are in the same piece of tube.

Integral Low Finned Tube Advantages


Offers 2.5-3 times the external surface area of bare tube

Enhanced heat exchanger efficiency means less tube is required to accomplish the same heat transfer as a bare tube

Low finned tube can increase the performance of an existing exchanger without the difficult and expensive task of building new shells etc

Reduced space and weight can be extremely valuable in offshore production or high elevation distillation columns. Low finned technology can transform large shell and tube exchangers into compact heat exchangers.

Low Finned Tube Properties


Low maintenance

Persistent against rust

Light weight

1. What is the fin efficiency?

Fin efficiency is defined as the ratio of actual heat flow of the fin to that which would be obtained with a fin of constant temperature uniformly equal to the base surface temperature, that is, one with infinite thermal conductivity.


2. What are low finned tubes?

Low Finned tube is a finned tube obtained through plastic cold deformation. The method consists in realizing, from a smooth tube, fins with a particular geometric form without removing material; this plastic deformation causes an increment of heat exchange efficiency, and allows to reduce the heat exchanger size.


3. How are low fin tubes made?

Low finned tubes involve rotational processing of the outer surface of steel tubes to create a fin shape. A steel pipe length of 25.4 mm (1 inch) per fin and 19 fins is a design often used. We can also produce units with 26 fins.
