SPIRAL FIN TUBE MACHINE High frequency welded spiral finned tube is one of the most widely used finned tubes.

It is a plain type fin, made by helically winding the fin strip on edge around the tube.

The fin is continuously welded to the tube by a high frequency electrical resistance welding process which leaves the tube essentially unchanged metallurgically.

The width of the weld is always greater than 90 percent of the thickness of the fin, assuring a strong bond between the fin and the tube for efficient heat transfer and long life.

Solid fins are preferred in fouling applications.

The finished finned tube is extremely strong mechanically and has greater resistance to bursting pressure than the bare tube due to the reinforcing effect of the fin.

Because of its excellent strength and resistance to deformation, this tubes are well suited for applications where severe abuse is expected in service.
