Product Description
DELLOK Power Industry Welded Longitudinal Finned Tube
Professional heat exchanger manufacturer with 20 years of experience, providing comprehensive heat transfer solutions for various industries including metallurgy, food processing, petrochemical, pharmaceutical, beverage production, wastewater treatment, and refrigeration systems.
Product Overview
Welded longitudinal finned tubes are engineered for high-temperature, high-pressure applications with elevated fin-side temperatures. These tubes are particularly suitable for installations requiring vertical orientation and applications where fluid drainage is critical.
Manufacturing Process
- Longitudinal I/L or U-shaped fins welded onto core tubes using resistance welding or filler metal welding
- Available in U-bend tubes and fin tube coil configurations
- Multiple fin types: one-piece shape, standard U-bent shape, cut & twist, perforated type
- Fin channels welded to tubes in opposite pairs with customizable height, quantity, and thickness
- Compatible with both OD tubes and NB pipes
Key Advantages
- Enhanced heat transfer rates for viscous liquids
- Perforated fin design for optimal liquid drainage
- Improved heat transfer efficiency in compact spaces
- Reduced installation space requirements
- Lower equipment costs with high operational reliability
- Reduced pressure drop and operational costs
- Enhanced structural stiffness and seismic performance
Industrial Applications
- Chemical and petrochemical processing
- Oil and power industry applications
- Heat exchangers and fired heaters
- Gas coolers and heaters
- Tank heating systems
