Product Description
Product Overview
DELLOK Carbon Steel Welded Stainless Steel Longitudinal Fin Tubes are precision-engineered heat transfer components manufactured using advanced resistance welding technology. These tubes feature longitudinally welded fins that significantly enhance heat exchange efficiency in industrial applications.
Manufacturing Process
Our longitudinal fin tubes are produced using precision resistance welding technology. The fin strip is formed into U-shaped channels, then welded diametrically opposed along the tube length. This advanced manufacturing process ensures superior bond strength and thermal performance.
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 optimal liquid drainage
- Ideal for horizontal heat exchanger applications
Performance Benefits
- Superior heat transfer efficiency in compact spaces
- Reduced installation space requirements
- Lower equipment costs with high operational reliability
- Minimized pressure drop and reduced operating costs
- Enhanced structural stiffness and seismic performance
Industrial Applications
- Chemical, petrochemical, oil, and power industries
- Heat exchangers and fired heaters
- Gas coolers and heaters
- Tank heating systems
