Product Description
The KL-type fin tube is manufactured from an ASME SA179 carbon steel seamless tube as the base, with Aluminium 1060 fin strip wound around the tube. The strip is knurled (K) into the tube surface to lock the fin foot firmly, and then wound (L) under controlled tension to achieve strong mechanical bonding and high thermal efficiency. This structure is widely used in air coolers, condensers, and process heat exchangers, especially in power generation and petrochemical applications.

Strong mechanical bond: Knurled and wound construction ensures firm grip of fins on the tube.
Enhanced heat transfer: Close tube-to-fin contact provides high thermal conductivity.
Corrosion resistance: Aluminium fins provide additional protection and durability.
Cost-effective: Lightweight structure with high efficiency, reducing system size and cost.
Durability: Resistant to vibration and thermal cycling in continuous operation.
Increased external surface area for better heat dissipation
Lightweight aluminium fins reduce equipment load
Reliable in high-temperature and corrosive service environments
Long operational life with reduced maintenance
