Description:

 HFW Helical Fin Tube For Heat exchanger

Application

Spirally Wound High Frequency Resistance Welded Finned Tubes are used in Heat Recovery Systems associated with Furnaces for Petrochemicals applications, and with Boilers for Power Generation and Waste Heat Recovery applications. The usage of finned tubes in Heat Exchangers reduce cost and size of the equipment which directly results in performance improvement.

Manufacturing Process

The High Frequency Resistance Welding process usually employs 400, 000 Hz current. With this technique, the fin is wound on edge around the tube spiraly and a continuous weld is obtained.

The High Frequency Resistance Welding process produces a strong metallurgical bond between the fin and the tube while minimizing the heat affected zone (HAZ) in the tube.

PROGEN follows International Standards for Dimensions, Tolerances and Tests for High Frequency Resistance Welded Finned Tubes.
