What is L-type Spiral Wound Finned Tube?

L-type spiral wound finned tube is a type of heat exchanger tube that has a continuous helical fin wound around the outside surface of the tube. The fins on the tube are tightly serrated, and they are wound in a continuous spiral, creating a helical configuration. The L-type fin has a rectangular shape, and its height is greater than that of the base metal or tube diameter. The L-type spiral wound finned tube presents a more extended surface area for thermal transfer and is effective for heat recovery applications.

The 'L' in L-type spiral wound finned tube denotes that the fins protrude from the tube surface in an L-shaped pattern when viewed from the end. This ensures better turbulence on the fin's surface, which results in improved heat transfer efficiency. The L-type spiral wound finned tube has a high heat transfer rate, and it is widely used in heat exchangers, air coolers, boilers, and other applications that require efficient heat transfer.

Advantages of L-type Spiral Wound Finned Tube
  • Increased Heat Transfer: Provides up to 8 times greater heat transfer than plain tubes.
  • More Compact Design: Allows for maximum heat transfer in a smaller footprint.
  • Higher Efficiency: Enhanced heat transfer efficiency compared to other types.
  • Longer Life: Tight bond between fin and tube provides robust, long-lasting performance.
  • Versatility: Customizable by adjusting fin geometry, pitch, thickness, and material.
  • Reduced Fouling: Less deposit formation compared to bare tubes.
  • Cost-Effective: Reduces manufacturing and installation costs while providing energy savings.
