Alloy / Steel Sprial Settated Fined Tube , Solid Power Plant Fin Tube OD X 2.9 MWT X 1660mm LG

HFW sprial settated fined tubes apply in Fired heater
ASME SA192 44.5 mm OD x 2.9 MWT x 1660mm LG
Segmented fin, CS, FPM300 x0.8mmTHK x 12.7mmH

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.

Reference Drawing :



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;








Packaging: sea worthy with plastic cap for each edge of core tube , finned tubes shall be put on the metal frame with wooden walls and plastic layer be considered between tubes rows to avoid damage and deformation of the fins
