Manufactured through latest welding technology with rigorous quality control process to ensure high and reliable performance even under extreme temperatures, corrosive environment and long hours of operation.

What Are V-Type Longitudinal Fin Tubes?

V-Type Longitudinal Fin Tubes, they are also known as, have their V-shaped fins attached along the longitudinal direction over the surface of a bare tube. Unlike conventional spirally fins, where the fins are helically wound along the tube length, these V-type longitudinal fins are directly arranged along the length of the tube providing longer heat transfer surfaces, thereby increasing the heat transfer performance.

The V-shape of the fin aids in distributing flow and creating turbulence, thus increasing the heat transfer coefficient values. The efficiency is significantly high for gas side heat transfer applications, where it's needed to increase the effective surface area for transferring heat. We, as an experienced V-Fin Longitudinal Tubing Manufacture in India supply these finned tubes in numerous materials, fin configurations and dimensions depending on the industrial requirements.

How V-Type Longitudinal Fin Tubes Improve Heat Transfer Efficiency


The primary function of longitudinal fins is to increase the effective heat transfer area without significantly increasing equipment size.

The V-shaped fin geometry offers several performance advantages:

  •   Enhanced Surface Area: Additional fin surfaces expose more area to the surrounding fluid or gas, improving heat exchange efficiency.
  •   Better Airflow Distribution: The V-profile helps create controlled turbulence, increasing convective heat transfer rates.
  •   Improved Thermal Performance: Heat is efficiently conducted from the base tube to the fins, maximizing energy transfer.
  •   Reduced Equipment Footprint: Higher thermal efficiency allows designers to achieve desired performance using smaller heat exchanger systems.
