Overview of V-Type Longitudinal Fin Tubes
The V-Type Longitudinal Fin Tubes are advanced heat transfer tubes that incorporate the use of V-channel fins resistance-welded to the outer wall of the base tube. The special V-channel construction increases the heat transfer area externally as well as creates turbulence in fluids, thereby increasing the efficiency of thermal transfer as compared to regular fins. These tubes are made by shaping metal strips in V-channels and then bonding them to the tube through axial resistance welding. Made from carbon steel, stainless steel, copper, aluminum, and alloys, the V-Type Longitudinal Fin Tubes have high corrosion resistance and good fluid drainage capabilities, along with superior strength under high pressure and temperature environments.

They are heat exchanger tubes with V-shaped fins welded along the tube length to increase heat transfer area.
They work by increasing surface area, allowing more heat to transfer between fluids and gases efficiently.
To improve heat transfer rate and enhance thermal efficiency by increasing contact area.
Yes, they are designed to withstand high pressure and high-temperature industrial conditions depending on material grade.
Longitudinal fin tubes have fins running along the tube length, while helical fin tubes have spiral-wrapped fins.
Yes, they are significantly more efficient because they provide much higher heat transfer surface area.
