High-Frequency Helically Finned Tubes
Rosink spiral finned tubes are the main components of economizers, heat recovery boilers and numerous other industrial heat exchanger applications. They are available with solid fins or with segmented fins. The geometry of Rosink finned tubes is adapted to specific customer requirements and flue gas characteristics.
Solid fins
The fins are helical wounded onto the tube and the fin is continuously fully welded to the tube.
Serrated fins
The fin strip is slotted at short intervals. A remaining height of 5 mm is left unslotted, which forms the continuous fin base. When the finstrip is helically wound onto the tube the serrated part of the finstrip devides at the outer end thus forming rectangular segments.
Standard fin materials
Almost any combination of tube and fin can be processed. However, the most commonly used fin materials are:
The fin thickness can be selected in 0.05 mm increments. The maximum fin thickness is 3.0 mm for solid fins. For segmented fins, the maximum fin strength is 2.0 mm for carbon steel. Other dimensions are available on request.
