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
Detailes of TP304L Base Tubes
Chemical Composition (%) max
| Grade | C | Mn | P | S | Si | Cr | Ni |
| TP304 | 0.03 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 8.0-11.0 |
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.
Mechanical Properties
| Grade | Tensile Strength min | Yield Strength min | Elongation in 2" or 50mm min |
| TP304L | 70ksi (485 MPa) | 25ksi (170 MPa) | 35% |
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.
