Product Description

Wound Fin Tube ASME SA179 KL Type With Aluminium Strip For Heat Exchanger

Product Description

KL-type wound fin tubes are produced by tightly wrapping an aluminum strip around the base carbon steel tube under controlled tension. During the process, the base of the aluminum strip is simultaneously knurled and wound, ensuring a tight mechanical bond between the fin and the tube. This structure provides good heat transfer efficiency and prevents fin loosening during service. KL-type fin tubes are widely used in heat exchangers, air coolers, and condensers where cost-effective and efficient thermal performance is required.

The finning is tight — you can tell they used a proper cold-forming process because the fins don't move at all when you try to wiggle them. We've had issues before with other suppliers where the fins would come loose after a few thermal cycles, but these ones feel solid.

As an engineer in Siberia, I tested these fin tubes in extreme cold (-30°C). The ASTM A213 T11 steel performed well with no thermal cracks, and cooling efficiency met expectations (88%). That said, the Russian-language documentation had translation errors in technical terms, causing minor confusion during installation.

No corrosion issues so far, though we're running below dew point carefully. Installation was straightforward—tube sheets lined up, ends clean, rolling into the header went smooth.
