Technical Specification:
Tube Outer Diameter (OD): Range from approximately 1 inch (25.4 mm) to several inches (e.g., 4 inches or 101.6 mm), or larger depending on the application.
Fin Height: Typically from 0.25 inches (6.35 mm) to 1 inch (25.4 mm) or more.
Fin Thickness: Can range from 0.02 inches (0.5 mm) to 0.1 inches (2.5 mm) or more.
Performance:
Heat Transfer Coefficient (U): This is a key performance metric that describes the overall ability of the finned tube to transfer heat. It is affected by the fin geometry, material properties, and fluid flow conditions.
Pressure Drop: The pressure drop across the finned tube is an important consideration in heat exchanger design. Higher fin density and serrations will increase pressure drop.
What Is Helical Serrated Finned Tubes?
The primary purpose of a helical serrated finned tube is to maximize heat transfer between the fluid flowing inside the tube and the surrounding environment (typically air or another fluid).
Increased Surface Area: The fins dramatically increase the surface area available for heat exchange.
Enhanced Turbulence: The serrated edges of the fins create turbulence in the flow of air (or fluid) around the fins. This turbulent flow disrupts the boundary layer (the stagnant layer of fluid that insulates the surface), further improving heat transfer.
Performance Characteristics Of Helical Serrated Finned Tubes
Enhanced Heat Transfer: The helical fin design increases the surface area in contact with the surrounding fluid, resulting in a higher heat transfer rate.
Improved Turbulence: Serrated edges can help by creating turbulent flow.
Compactness: Finned tubes are more compact compared to non-finned tubes.
Material Compatibility: Compatible with multiple materials.
Higher Fin Density: The image is short, so it is difficult to determine the density that the full piece offers.
Difficult to Clean: The serrations and the tight density could create challenging spaces to clean.

Applications Of Helical Serrated Finned Tubes
Heat Exchangers: The most common and broad application.
Air-Cooled Heat Exchangers: These are used in situations where a process fluid needs to be cooled, and air is the cooling medium. These are often found in industrial settings where water cooling is not practical or economical.
Shell and Tube Heat Exchangers: Helical serrated finned tubes can be used inside shell and tube heat exchangers to enhance the heat transfer between the shell-side and tube-side fluids.
Condensers and Evaporators: In refrigeration and air conditioning systems, these finned tubes are used in condensers (to reject heat) and evaporators (to absorb heat).
Air Preheaters: Used in heating systems to recover waste heat from exhaust gases to preheat incoming air, improving the overall efficiency of the system.
Economizers: Used in boiler systems to preheat the feed water using the heat from flue gases. This increases boiler efficiency and reduces fuel consumption. The fins help to extract more heat from the exhaust gases.
Industrial Processes: Many industrial processes require precise temperature control. Helical serrated finned tubes can be found in various processes within.

Frequently Asked Questions
About Helical Serrated Finned Tubes For Heat Exchangers
In what types of heat exchangers are helical serrated finned tubes commonly used?
Air-Cooled Heat Exchangers (ACHEs): Where air is the cooling medium. The fins significantly enhance heat dissipation into the air.
Shell and Tube Heat Exchangers: They can be inserted within the shell to improve heat exchange between fluids.
Waste Heat Recovery Systems: Efficiently extracting heat from exhaust streams.
HVAC Systems: In condensers and evaporators where maximizing heat exchange is important.
What are the advantages of serrated fins compared to smooth, continuous fins in heat exchangers?
Increasing Surface Area: Serrations add a small amount of extra surface area.
Improved Heat Transfer Coefficient: The overall effect is a higher heat transfer coefficient (U-value).
Reduced Fouling: Because the increased surface area allows for more even heating of the tube, deposits may be reduced.
What is the typical operating temperature range for helical serrated finned tubes made from different materials?
Aluminum: Up to approximately 200-250°C (392-482°F).
Steel: Can handle much higher temperatures, up to 500°C (932°F) or more, depending on the alloy.
Stainless Steel: Suitable for high-temperature and corrosive environments.
Copper: Generally lower temperature limits than steel, but good for moderate temperature, high heat flux applications.
How does the manufacturing process ensure a good thermal bond between the fins and the tube?
Welding: Continuous welding techniques (e.g., high-frequency welding) are used to create a strong and thermally conductive bond.
Brazing: Provides excellent thermal contact, especially for dissimilar materials.
Extrusion: (For aluminum fins) Creates an integral fin where the fin is formed directly from the tube material. This offers superior thermal contact.
What maintenance is required to ensure the longevity and performance of heat exchangers using helical serrated finned tubes?
Regular Cleaning: Removing dust, dirt, and scale buildup from the fin surfaces.
Inspection: Checking for corrosion, erosion, fin damage, and leaks.
Pressure Testing: Periodically testing for tube leaks.
What is the maximum length of helical serrated finned tubes that you can produce?
We can manufacture helical serrated finned tubes up to 12 meters in length, depending on your specifications and requirements.
Can you supply samples of helical serrated finned tubes for evaluation?
Yes, we can provide samples upon request to help you assess the quality and suitability of our products for your specific applications.
What are your lead times for orders of helical serrated finned tubes?
