The Extruded Fin Tube also known as� Bimetallic Fin Tube� is one of the most preferred finning processes for various applications.
Manufacturing process:
Fin is produced by the rolling method (three-roll oblique rolling). Its working principle is: The smooth tube is lined with a mandrel, the tube material is driven by the roller blade to make a spiral linear movement, and is rolled by the roller. The hole pattern composed of the groove and the core rod is gradually processed with fins on its outer surface. In order to facilitate the formation of fins, the rolling parts adopt three stages of biting, rolling, and shaping during the deformation process, so that the processed fins are complete, smooth, and regular. The finned tube produced by this method is based on the base tube and the outer fin is an organic whole, so there is no problem of contact thermal resistance loss and electrical corrosion. It has good heat transfer efficiency and strong resistance to deformation. Extruded finned tubes consist of a light pipe and fins â??attachedâ?? to it. The structural parameters are mainly the inner diameter and outer diameter of the finned tube, the wall thickness of the finned tube, the fin pitch, the fin thickness and the fin height.
Material Options:
We offer the widest range of material in the industry and can extend it on request in case of special requirements for heat conductivity, mechanical properties or corrosion resistance. Below are our regular materials` combination.
A. Copper aluminum composite finned tube
B. Steel aluminum composite finned tube
C. Pure aluminum finned tube
D. Pure copper finned tube
Fin Height Options:
A. Low finned tubes
The fins of the low finned tube are extruded directly from the tube material. The fin height is only 1-2 mm. The common low fins are 1.6 mm in the shell- and-tube heat exchanger. This kind of finned tube does not need to consider the contact thermal resistance with the tube.
B. Middle finned tubes
The fin height of the finned tube is about 3.2 mm, which is often used in pressure vessel equipment such as shell and tube heat exchangers.
C. High finned tubes
The finned tubes are usually used in air heat exchangers, whose height is lower than 16mm, depending on working conditions.
D. Customized specification, please reach to us for more details.
Extruded Finned Tubes Characteristic:
A. High heat transfer performance and low contact thermal resistance
B. The contact area between fins and tubes is large, and the connection is tight and firm.
C. Good corrosion resistance, stable performance for long-term use.
D. Fins have good rigidity and are not easy deform.
E. Light weight and Low cost.
F. Low air resistance
G. Easy to clean
