Product Introduction: Advanced Finned Tubes for Efficient Heat Transfer

In the competitive world of heat exchange technology, the ability to enhance efficiency and durability is essential. Our range of finned tubes is meticulously engineered to meet the rigorous demands of various industries, offering innovative solutions for improved heat transfer and operational reliability. This document highlights our key products—High-Frequency Welded Helical Finned Tubes, Extruded Finned Tubes, and KL-Type Fin Tubes—detailing their specifications, advantages, and applications.

A) High-Frequency Welded Helical Finned Tubes

High-Frequency Welded Helical Finned Tubes are designed for maximum heat transfer efficiency. These tubes feature steel fins helically wrapped around a steel pipe and are continuously welded using high-frequency electric currents. This process not only reduces flow resistance and metal consumption but also enhances the reliability of heat transfer equipment.

• Heat Transfer Advantage: The efficiency is 6-10 times greater than that of bare tubes, making it ideal for demanding heat transfer applications.
• Materials: The tube can be made from stainless steel or carbon steel, while fins can be constructed from aluminum, copper, or carbon steel.
• Applications: Widely used in power stations, chemical plants, and petrochemical industries for applications requiring enhanced heat transfer.

B) Extruded Finned Tubes

Extruded Finned Tubes are developed from bimetallic tubes, comprising a base tube and an aluminum muff tube. During the cold rolling process, fins are formed from the wall thickness of the aluminum muff tube. This design provides excellent corrosion protection, as the base tube remains shielded from atmospheric exposure between the fins.

• Materials: Base tubes can be carbon steel, stainless steel, or copper, while fins are made of aluminum.
• Corrosion Protection: Offers significant protection thus extending the service life of the base tube.
• Applications: Ideal for air cooling, gas processing facilities, and industries where environmental resistance is crucial.

C) KL-Type Fin Tube

KL-Type Fin Tubes leverage an innovative design where fins have a knurled L-shaped base pressured onto the tube for secure attachment.

• Materials:
  • Fin: Aluminum, Copper
  • Tube: Carbon steels (ASTM A179/A214, St 35.8), low-alloy steels, stainless steels, copper-nickel alloys, aluminum bronze, copper, nickel alloys.
• Sizes: Tube size ranges from 12.70mm to 50.8mm, with fin size between 7-11.5 fins per inch and a maximum fin height of 16mm.
• Manufacturing Process: The fins are formed by winding an L-shaped strip around the tube and joined together to cover the finned surface completely, with both ends clamped for stability.
• Advantages: Economical, capable of withstanding temperatures up to 130°C without risks of atmospheric corrosion or thermal stress.
• Applications: Extensively used in petroleum, chemical, and petrochemical industries, as well as in power generation and HVAC systems.
