|General Low Fin Tubes Production Capacity||Specifications of Low Fin Tubes('N' Fins)|
Finning Facility: 10 finning machines;
Daily capacity up to 3000 meters;
|Tube OD: 12.7 mm~25.4mm|
Tube Length: 18 meters max.
Fin Height: 1.2 mm ~2.77mm
Fin Thickness: appr. 0.3mm

Manufacturing process: The fins are rolled out of outer wall of the
plain tubes by a pass roller. Tubes and fins are in same piece
tube. We call it [N" fin type.
Delivery of Low Fin Tubes
We can provide the integral low fin tubes with un-finned section
gaps( 5mm Min.) in the middle of core tube OR bent with designed
The integral low fin tube quality is assured by hydrostatic or
pneumatic tests, eddy current tests & MARCO tests in order to
verify design specifications.

- We have more than 12,000 square meters workshop, including 12
finning machines, daily extrusion capacity up to 3,500 meters.
- The finning machines of Integral Low Fin Tubes are designed and
assembled by ourselves and we can offer you finning machines and
all the parts of accessories etc...
- The Integral Low Fins are rolled out of the tube surface to
increase the tubes external surface area, without affecting any
- Low Fins are very useful for tight condensers and exhibits high
efficiency of heat transfer.
- Economical solutions of heat exchange problems of media with
different heat conduction abilities or different current
- High chemical-, thermal- and mechanical resistance, suitable for
rough operation conditions.
