Laser Welded Finned Tubes

Laser Welded Finned Tubes are manufactured by helically winding strip onto tubes. The heat transfer fins are attached to the surface of tubing in a unique laser process within a protected atmosphere. This method produces high quality finned tubes in a process  and tube material can be selected according to specific design requirements. The small heat-affected zone in connection with thin weld seams avoid any deformation of the material. This results in a high stability of shape and a great accuracy of size of the welded finned tube.
