Manufacturing Process
Our longitudinal finned tubes are produced using precision resistance welding technology. The fin strip is first formed into U-shaped channels, then welded in pairs along the tube length using diametrically opposed positioning, ensuring optimal heat transfer surface distribution.
Key Advantages
- Enhanced heat transfer efficiency in compact spaces
- Reduced installation space requirements
- Lower equipment costs with high operational reliability
- Minimized pressure drop and reduced operational costs
- Improved structural stiffness and seismic performance
- Optimized metal consumption while maximizing heat transfer
Surface Treatment & Protection
All tubes (except stainless steel) undergo precision polishing to near-white condition before welding. Post-welding, protective coatings are applied to ensure 3-month corrosion prevention during transportation and storage, with extended protection options available.
Industry Applications
Our longitudinal finned tubes are ideal for:
- Double pipe heat exchangers
- Multi-tube heat exchangers
- Fire rated heaters and gas coolers
- Tank heating systems
- Oil, power, chemical, and petrochemical industries
Quality Assurance
We maintain rigorous quality control throughout the manufacturing process, including:
- Raw material inspection and certification
- Production process monitoring
- Water pressure and strength testing
- Third-party verification available
- Comprehensive mill test certifications for tubes and fins
Technical Information
Longitudinal finned tubes are particularly effective in air heat exchangers where heat transfer occurs between liquids and gases. The increased surface area significantly enhances heat transfer rates, making them ideal for applications requiring efficient thermal management.
