Carbon steel finned tubes are high-efficiency heat transfer elements widely used in industrial heat exchange equipment. They increase heat dissipation area by adding fins to the surface of a carbon steel base tube, thereby improving heat transfer efficiency.
The core function of carbon steel finned tubes is to reduce contact thermal resistance and provide corrosion and wear resistance. They are commonly used in waste heat recovery and heat exchange equipment.
Carbon Steel Finned Tube Manufacturing Process
The main production processes for carbon steel finned tubes include high-frequency welding and three-roll skew rolling. High-frequency welded spiral finned tubes are widely used due to their high degree of automation. Three-roll skew rolling achieves seamless bonding through integral rolling. In addition, welding is used to connect the fins to the tube body, ensuring good thermal conductivity and mechanical strength; extrusion molding is used to produce the shape and size of the fins.
Main Advantages of Carbon Steel Finned Tubes
Excellent Mechanical Properties: Carbon steel has good strength and hardness, can withstand high pressure and temperature, and is suitable for use in high-pressure or high-temperature conditions.
High Thermal Conductivity: Carbon steel has a high thermal conductivity, effectively transferring heat and ensuring a highly efficient heat exchange process.
Economical Advantages: Carbon steel is relatively inexpensive and abundant, with mature processing technology, resulting in a significant cost advantage.
Wide Applicability: Carbon steel finned tubes are widely used in various industries such as power, petroleum, chemical, metallurgy, air conditioning, and refrigeration.
Corrosion Resistance: Surface treatments (such as galvanizing and painting) can significantly improve its corrosion resistance and extend its service life.
Typical Applications of Carbon Steel Finned Tubes
Air Radiators: Carbon steel finned tubes are used in refrigeration, air conditioning, and heat recovery systems. The fin design increases the contact area with air, improving heat exchange efficiency.
Industrial Heat Exchange Systems: Carbon steel finned tubes meet the high-load heat exchange requirements of waste heat recovery equipment in fields such as petrochemicals, power, and metallurgy.
Power Plant Air-Cooling Technology: As a core component of air-cooled condensers, carbon steel finned tubes directly affect the cooling effect.
Carbon steel finned tubes, with their superior mechanical properties, thermal conductivity, and economic efficiency, have become the preferred component in industrial heat exchange. Manufactured through processes such as high-frequency welding or rolling, and supplemented with surface treatment, they can adapt to various complex operating conditions and are widely used in heat dissipation, waste heat recovery, and industrial cooling systems.
