Description:
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.
Products&Inspection Deatails:
Following documentations should be reviewed & endorsed:
