Finned tube:

The finned tube provide by us is Extruded Type, which is different from the 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.

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.


Material: Stainless Steel+Stainless Steel, Carbon Steel+Carbon Steel, Alloy+Alloy etc.
Bare tube OD: 16-219mm Fin Pitch: 3-25mm Fin Height: 5-30mm Fin Thick: 0.8-3mm

Application: The High Frequency Resistance Welded Helical Fin Tubes are widely applied in fired heaters, heat exchanger, boilers, economizers, pre-heaters, heat pipes, heaters etc…

Capacity: Seven ERW High Frequency fining lines, daily capacity around 50 tons,length≤28meters;
