Helical finned tubes are specialized heat transfer elements composed of a base tube and continuous spiral fins welded helically along the tube’s outer surface. They are typically made from carbon steel, stainless steel, or alloy steel depending on the thermal and corrosion requirements. The fins are mechanically bonded or continuously welded to the base tube to ensure excellent heat conductivity and durability.
Base Tube Material: Carbon steel, stainless steel, or alloy steel
Fin Material: Carbon steel, stainless steel, or aluminum
Outer Diameter: 19mm – 63.5mm
Fin Height: 6mm – 25mm
Fin Thickness: 0.8mm – 3.0mm
Fin Pitch: 2.5mm – 10mm
Tube Length: Up to 12 meters (customizable)
Welding Method: High-frequency resistance welding or continuous welding
High mechanical strength and superior heat transfer efficiency
Excellent bonding between fin and base tube ensuring low contact resistance
Resistant to corrosion, oxidation, and thermal stress at high temperatures
Customizable fin pitch, height, and materials to suit specific heat exchanger applications
Long service life and reduced maintenance costs
From a professional manufacturer’s perspective, we address the key technical concerns of industrial clients:
Straightness & Tolerance Control: Tubes are manufactured under strict straightness control (≤1mm/m) and diameter tolerance within ±0.3mm, ensuring perfect fit and easy assembly in heat exchanger systems.
Uniform Welding Quality: Continuous automatic welding guarantees consistent fin attachment and uniform heat transfer performance along the entire tube length.
Material Traceability & Quality Assurance: Every batch of material is traceable and complies with ASTM, EN, or GB standards. All welds are 100% visually and dimensionally inspected.
Thermal Performance Optimization: Precise control of fin geometry ensures optimal surface area ratio, maximizing heat exchange efficiency and reducing thermal resistance.
Customization & OEM Service: Tailored designs and alloy combinations to meet customers’ pressure, temperature, and corrosion resistance requirements.
