Corrugated Fin Tubes Stainless Steel S30403 TP304L For Heat Exchanger

Corrugated Fin Tubes Stainless Steel S30403 TP304L For Heat Exchanger


Difinition


The corrugated tube is a new type of high efficiency heat exchange tube instead of the row tube.designed to enhance thermal performance by increasing the surface area available for heat transfer. These tubes feature external fins that are corrugated, improving their ability to transfer heat in various applications.Typically made from materials like copper, aluminum, or stainless steel, providing excellent thermal conductivity and corrosion resistance.
Applications of Corrugated Fin Tubes

1.Heating and Cooling Systems: Used in HVAC systems, boilers, and chillers


2.Power Generation: Utilized in heat recovery systems and steam generators


3.Chemical Processing: Essential in reactors and heat exchangers


4.Automotive Radiators: Employed in car radiators


5.Marine Applications: Used in ship cooling systems

For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.040% is necessary in Grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500 in. [12.7 mm] in outside diameter and light wall are those less than 0.049 in. [1.2 mm] in minimum wall thickness.

Advantages of Corrugated Fin Tubes


Corrugated fin tubes have the advantages of strong corrosion resistance, longer service life, no pitting corrosion and low price.
1.The stainless steel corrugated tube of corrugated tube heat exchanger is made of high-quality stainless steel material, which is corrosion-resistant.
2.The special internal and external waveforms of the corrugated tube are more and more important. The turbulent medium constantly washes the inner and outer surface of the heat exchange tube, and the dirt is difficult to accumulate on the surface.
Even if the scale is formed, because the corrugated tube is a flexible element, after the effect of temperature difference in the working process, all parts of the corrugated tube will be affected. The curvature of the corrugated tube is constantly changing. Although the deformation caused by this curvature change is not very large, the linear expansion coefficient of the dirt and the metal corrugated tube is quite different.
Therefore, a large pull-out force will be generated between the dirt and the corrugated tube surface, which is enough to make the scale fall off and realize automatic cleaning and automatic descaling. Especially, this point is incomparable to the row of tubes and other heat exchangers, and the stress distribution is uniform Good corrosion resistance.
3. As the corrugated tube adopts ultra-thin wall stainless steel material, on the one hand, it improves the service life of the product, at the same time, it also greatly reduces the weight of the product and saves the material.
4. Due to the reduction of the operation and maintenance cost and the reduction of the floor area, the performance price ratio of the product is greatly improved, and the economic benefit is obvious.
