Quick Detail:

High Frequency Resistance Welded Helical Steel Fin Tubes is widely used in the recovery of waste heat from boiler flue gas.

General HF welding production capacity

General specifications of HF welding fin tubes

Welding Facility: 4 finning machines;
Daily production capacity up to 40 tons;
HFW Fin type: solid plain and serrated.

Tube OD : 19mm min.
Tube Length : No limit
Fin Height : 32 mm max.
Fin Thickness: 0.8mm min
Fin Pitch : min. 4 mm for solid fins

and 3.3mm for serrated fins.

General Manufacturing Process:

The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using high frequency resistance welding technique.
We produce both solid plain and serrated helical welded steel finned tube. And also, all spiral welding tubes could be bent in the middle or at the end of fin tubes, we call it Hairpin tubes.
