P235 GH TC1/2 SMLS Carbon Steel Tube, Welded Helical Bent Evaporator Fin Tube

 

Introduction:
High Frequency Resistance Welded Helical Steel Fin Tubes is widely used in the recovery of waste heat from boiler flue gas.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. All of them are outside-Red oxide zinc phosphate primer and inside volatile corrosion inhibitor (VCI) in water soluble tablet form. Its suits various area such as The High Frequency Resistance Welded Helical Fin Tubes are widely applied in fired heaters, heat exchanger, boilers, economizers, pre-heaters, coolers, heat pipes, heaters etc….

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.
