^{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.}

^{Advantages of laser welding finned tube}

^{Avoidance of gap corrosion
➔ Longer lifetime
Easy to clean and sterilize
➔ Laser fin meets the requirements:
➔ food & beverage
➔ pharmaceutical industry
Optimal heat transfer, reduced material
