DELLOK Laser Welded Copper Fin Tube

^{Laser Welded Finned Tube Product Description:}

^{1.Thin and continuous ideal seams}

^{2.Small heat affected area}

^{3.Slightly discolored welding parts}

^{4.The tubes and fins have only slight microstructure changes}

^{5.High heat forms seams}

^{6.Since the high welding integrity between the tube and the fins is avoided, the crevice corrosion is avoided, thereby improving safety}

^{7.Laser welding is carried out in a protective atmosphere, so the weld is free of impurities}

^{Laser Welding Fin Tube Manufacturing Process:}

^{Laser welding is a high intensity laser beam to the metal surface, through the interaction of laser and metal, metal absorption laser into heat to make the metal melt after the formation of cooling crystallization welding.}

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

^{1.The thickness of base tube and fin can be 0.8-1.5 mm and 0.3-1 mm respectively, which greatly saves the material cost compared with other processes.}

^{2.High penetration rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance.}

^{3.No material restriction, different materials can be used for processing.}

^{4.Easy for secondary processing, can be directly coiled and bent.}

^{5.The welding heat affected zone and the metallographic change are small, which makes it possible to process the small diameter finned tube.}

^{6.A variety of material combinations are available, titanium/ copper, titanium/titanium, carbon steel/carbon steel, stainless steel/stainless steel, stainless steel/copper, etc.}

^{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.}
