Product Overview
Welded longitudinal finned tubes are manufactured using resistance welding technology, where U-shaped fin channels are welded diametrically opposed along the tube length. This construction ensures optimal heat transfer performance and structural integrity.
Key Advantages
  • Extended service life compared to ordinary helical fin tubes
  • Enhanced safety and energy efficiency
  • Improved heat transfer rates for viscous liquids
  • Perforated fin options available for liquid drainage requirements
  • Ideal for horizontal heat exchanger applications

Frequently Asked Questions
What Are Finned Tubes Used For?
Finned tubes are particularly effective in air heat exchangers where heat transfer occurs between liquids and gases. The increased surface area facilitates faster heat transfer, especially beneficial when dealing with lower heat coefficients on the air side.
What is a Longitudinal Finned Tube?
Longitudinal finned tubes, also known as Brown Fintubes, are manufactured using high-frequency resistance welding to attach fins longitudinally along the tube length.
What Are the Properties of Longitudinal Finned Tubes?
These tubes improve heat transfer efficiency in limited spaces, reduce equipment costs, enhance operational reliability, lower pressure drops, and increase structural stiffness.
What Are Applications of Longitudinal Finned Tubes?
Our longitudinal finned tubes serve various applications including double pipe heat exchangers, multi-tube heat exchangers, fire rated heaters, gas coolers, and tank heaters across oil, power, chemical, and petrochemical industries.
