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.

Provide higher operational efficiency due to optimized fin attachment.
Extend service life of heat exchangers in demanding industrial environments.
Suitable for both air-side and gas-side applications, offering flexibility across industries.
Heat exchangers in petrochemical plants, power stations, and refineries
Condensers and air preheaters in thermal power generation
Air-cooled heat exchangers in fertilizer and chemical industries
Waste heat recovery systems
Strong fin-to-tube bond: Knurled and locked foot resists loosening during thermal cycling.
Enhanced heat transfer: Maximum contact area ensures efficient thermal conductivity.
Corrosion resistance: Aluminium or copper fins provide protective covering for the tube surface.
Durable & reliable: Withstands vibration and high-temperature fluctuations.
Cost-effective: Lower material and maintenance costs compared with other finned tube types.
