High Finned Tubes have extruded fin heights up to 0.625″ (16mm). Single metal and bi-metallic finned tubes are available. Bi-metal finned tubes have a separate alloy liner tube inside the extruded fins. The mono-metal finned tubes have no liner tube with the fins integral with the tube.

- Rings: Carbon steel, Aluminium, Hot dip galvanizing
Finned tube:
The finned tube provide by us is Extruded Type, which is different from the normal ones through HF Welding and Wrapping method. The fins are obtained by roll forming the outer surface of a soft seamless plain tube.
The technology simply squeezes the wall thickness transforming into straight fins on the tube. So the fin and the tube are integrated and inseparable, which avoids the heat resistance between fin and tube, and optimizes heat exchange efficiency.
Based on this structure, the Extruded type can survive more severe working conditions than other finned tubes.
Also it, on the other hand, shows several unique features such as enhanced physical structure, resistance to vibration, anti-corrosion ability, and long service life, etc.
