3. What Is a Spiral Welded Fin Tube

The spiral welded fin tube consists of a metal fin strip welded in a spiral pattern around a base tube. Fin strip is commonly applied to the tube with high frequency welding technology. As a result, the strip is firmly secured to the tube for its full length.

The spiral design allows air to flow evenly across the entire tube. This allows your heat exchanger to run much more efficiently by optimizing heat transfer.

Furthermore, the welding creates a very strong mechanical bond. As a result, the fins are less likely to loosen due to vibration or mechanical force.

4 Types of Spiral Welded Fin Tubes

  • 1 Bare Tube

The bare tube transports the working fluid through the heat exchanger. Carbon steel, stainless steel, and alloy steel are typical materials manufacturers use to construct them.

  • 2 Spiral Fin

The fin is an external metal strip that spirals around the bare tube.

  • 3 Weld

The fin and tube connect through a high-frequency weld. Thus, this joint has strong metal-to-metal strength and conductivity.

The welded connection creates the strong structure of a spiral welded fin tube.

5. Reasons Spiral Welded Fin Tubes Conduct Heat Better

  • The spiral design increases the surface area of the tube.
  • Thus, the fin tube can transfer heat more rapidly.
  • The spiral shape also causes turbulence in the air flowing through the heat exchanger. Therefore, this promotes convection heat transfer.
  • Finally, the welded joint creates excellent thermal conductivity between the fin and tube. Heat can flow quickly through the fin.

For these reasons, spiral welded fin tubes are common in air cooled systems.

6. Beneficios

  • There are multiple benefits of the spiral welded fin tube from a technical standpoint.
  • First of all, welding provides excellent mechanical adhesion. As a result, fins will not move when the equipment is operating.
  • Second, a spiral fin design allows for increased heat transfer surface area. As a result, better performance of equipment can be achieved.
  • Lastly, since fins are welded on, they can prevent vibration and thermal elongation from taking place. As a result, you can enjoy a long service life of the tube.

Some other benefits of spiral welded fin tubes are:

  • Transferencia eficaz del calor
  • Mechanical strength
  • Resistance to vibration
  • Uniform fin pitch and geometry
  • Larga vida útil
  • Excellent durability for severe applications

For these reasons and many more, numerous industries choose spiral welded fin tubes.

7. Spiral Welded Fin Tube vs Other Fin Tubes

  • Spiral Welded Fin Tube vs Extruded Fin Tube

Extruded fins are created by mechanically pulling the fin through a shaping die. On the other hand, spiral welded fins are attached via welding. As such, welded fins can handle higher temperatures than extruded fins.

  • Spiral Welded Fin Tube vs L-Foot Fin Tube

L-foot fins are applied to a tube by mechanically wrapping it around. Conversely, welded fins provide stronger adhesion to the tube. Thus, welded fin tubes are ideal for heavy duty industrial applications.

  • Spiral Welded Fin Tube vs Low Fin Tube

Low fin tubes have shallow fins that are rolled onto the surface of the tube. In comparison, a spiral welded design gives you more surface area for heat transfer.

Thus, spiral welded fin tubes allow for higher heat transfer coefficients.

8. Aplicaciones

Spiral welded fin tube sees application across various industries.

Typical uses are:

  • Air cooled exchangers
  • Economizadores de caldera
  • Waste heat recovery units
  • Petrochemical facilities
  • Centrales eléctricas
  • Oil & gas units
  • Industrial furnaces

Engineers commonly specify spiral welded fin tubes as they require dependable heat transfer surfaces.

9. How we Make Spiral Welded Fin Tube at Bangwin Thermal

We have state-of-the-art machinery to produce spiral welded fin tube products.

Initially, we use premium grade base tubes. Then we supply metal fin strips into the welding unit. As the tube spins, the strip is wrapped onto the surface.

Simultaneously, high frequency welding bonds the fin to the tube continuously. As a result, you get durable fin assemblies.

Once completed, we test the fin pitch, fin height, and weld strength. This means all of our spiral welded fin tubes pass strict quality checks.
