^{Laser Welded Finned Tube Product Description:}

^{Laser welded spiral Fin Tube is using a laser welding machine processing.}

^{In traditional the spiral fin tubes are using high frequency welding, resistance welding and other technology to make the stainless steel fin attached on the steel pipe. Laser Welding Finned Tube, the welding process has its shortcomings that cannot be overcome.}

^{While The laser welding spiral finned tube has full automatic welding process,save the manpower cost; secondly, laser welding fin solid and strong, high tensile strength test were qualified; laser welding more efficiency advantages etc.}

^{The laser welding machine is the most advanced laser welding equipment for spiral finned tube . Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welded spiral finned tube are better than the traditional cooling pipe.}

^{Laser Welding Fin Tube 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 advanced laser welding technique.}

^{Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:}

^{1.thin, continuous weld seam}

^{2.small heat-affected zone}

^{3.only slight discoloration weld site}

^{4.only slight microstructural change in tube and fin}

^{5.high utilization of heat for forming the seam}

^{6.increased safety because of the avoidance of crevice corrosion due to the high weld integrity between tube and fin}

^{7.no impurity of the weld seam, as the Laser-welding is carried out under a protective atmosphere.}

^{Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:}

^{1.Advanced technology: the product using laser welding technology, 100% penetration rate.}

^{2.Stable quality: the equipment using full automatic production process, product quality is stable and reliable.}

^{3.High heat efficiency: the product has smaller fin spacing and thin tubes to increase the heat transfer area and heat transfer rate.}

^{4.It can be bent into different shapes to meet different production needs.}

^{Laser Welded Finned Tube(Stainless Steel Welded Pipe) Applications:}

^{1.Power plant}

^{Cooling towers or cooling water recooling plants with dry or wet operation}

^{Flue gas cooling and heating in flue gas desulfurization scrubbers (FGD) and nitrogen removing plants}

^{2.Chemical industry}

^{Heat exchangers of all kinds for cooling and heating of liquids and gases}

^{Heat exchangers tor nitric acid (HNO3) plants, e.g. for the fertilizer industry}

^{3.Heat recovery plant}

^{Flue gas coolers}

^{4.Thermal Industry}

^{Primary heat exchangers in gas heating boilers}

^{Secondary heat exchangers for domestic water heating in condensing boilers}
