What Is Spiral Finned Tube?
A spiral finned tube is an efficient heat transfer element with fins spirally wound around it, increasing the surface area for heat transfe. This design enhances heat transfer, reduces flow resistance, and decreases metal consumption, improving the economy and operational reliability of heat exchange equipment. The tube itself is typically made from metal such as copper, aluminum, carbon steel, or stainless steel. The fins can be made from the same material or a different one with higher thermal conductivity, like copper or aluminum. They are often tension wound onto individual tubes.
Performance Characteristics Of Spiral Finned Tube
Enhanced Heat Transfer: This is the primary goal. The spiral fins significantly increase the surface area in contact with the surrounding fluid (air, liquid, etc.). This assumes that a fluid flows through the center of the tube.
Turbulent Flow: The fins likely induce some turbulence in the fluid flowing around the tube (on the outside of the tube). This turbulent flow disrupts the boundary layer (a thin layer of stagnant fluid that insulates the surface), further enhancing heat transfer.
Compactness: Although not explicitly visible, the image implies a compact heat transfer solution. The fins allow for a lot of heat transfer surface area in a relatively small volume.
Material: Without knowing the specific material, we can assume that the tube is made from a material with good thermal conductivity

Frequently Asked Questions
About Spiral Finned Tube For Heat Exchangers
Can the dimensions (diameter, length, fin height, fin spacing) of the spiral finned tube be customized for my specific application?
Yes, most manufacturers offer custom design options to optimize the tube for your specific needs. Factors like fluid flow rates, temperature differences, and space constraints will influence the optimal dimensions.
What are the primary applications of spiral finned tubes in heat exchangers?
How does the fin density (fins per inch) affect heat exchanger performance?
Higher fin density increases the surface area for heat transfer, improving performance up to a point. Beyond an optimal density, the increased airflow resistance (or fluid flow resistance) can reduce the overall heat transfer coefficient.
What materials are typically used to manufacture spiral finned tubes?
Aluminum: Lightweight and good thermal conductivity; often used for air-cooled heat exchangers.
Copper: Excellent thermal conductivity and corrosion resistance; suitable for demanding applications.
Carbon Steel: Strong and cost-effective; used in many industrial applications.
Stainless Steel: Good corrosion resistance, high-temperature strength; used in harsh environments.
What maintenance is required for spiral finned tube heat exchangers?
Cleaning: Removing deposits and fouling from the fin surfaces.
Inspection: Checking for corrosion, erosion, and mechanical damage.
Leak Testing: Periodically testing for leaks in the tubes.
What is the pressure drop associated with using spiral finned tubes in a heat exchanger, and how does this affect the pumping power requirements?
Spiral fins will increase the pressure drop compared to smooth tubes. The fin density and geometry significantly influence the pressure drop. A higher pressure drop means higher pumping power requirements. It’s essential to carefully select the fin design to balance heat transfer performance with acceptable pressure drop.
Can you supply samples of aluminum fin 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 aluminum fin tubes?
Our standard lead time is typically 4-5 weeks, but we can expedite production for urgent orders, depending on capacity and requirements.
