High Frequency Welding Fin Tube (“HFW” Type)
The fin strip is welded continuously and spirally wound onto a polished plain tube. And the tube and fins are bonded together by using high frequency resistance welding technique. This manufacturing method ensures high heat transfer coefficient and a perfect contact between plain tube and fins.
The welded fins could be solid and serrated. And also, all helical welded tubes could be BENT in the middle or at both ends; we call it 'Hairpin' tubes.
Welded finned tubes are used in fired heater, economizers, boilers, pre-heaters etc…
Operation temperature: 550℃max.
Tube materials: carbon steel, stainless steel, alloy steel can be applied.
Fin material: carbon steel, stainless steel
