DELLOK Laser Welded Copper Fin Tube

^{DELLOK Laser Welded Copper Fin Tube}

^{About Us}

^{DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) was
established in 2002, which is located in Jiangsu, China. After many
years of development, the company now has 66 million yuan in fixed
assets, more than 200 employees, and 33 technical staffs. We have 4
aluminum processing production lines, with the annual processing
capacity of more than 20,000 tons; And we have 5 tube-drawing
production lines; 47 fintube production lines, 1 imported
production line from American with the brand of McElroy , with the
annual production capacity of 12 million meters the above. Quality
is the theme of eternal pursuit of winner -Production workshop-
Meticulous works, standardized management system and systematic
quality assurance are Dellok(YONGHUI)'s best commitment to quality.
In Dellok(YONGHUI), the quality control is not only the detection
of the final process, but throughout the entire production process.
We implement a set of quality control and assurance systems. Each
batch of pipes is sampled and tested, and records are kept as a
quality guarantee for the final product.}

^{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.}

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

^{1.Power Plants}

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

^{Sodium coolers for Fast Breeder power plants}

^{Flue gas cooling and heating in fl ue gas desulfurisation scrubbers
(FGD) and nitrogen removing plants}

^{2.Chemical and Pharmaceutical Industry Food & Beverage}

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

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

^{Heat exchangers for milk powder production}

^{3.Heat Recovery Plants}

^{Flue gas coolers}

^Economizers

^{Waste Heat Recovery Units (WHRU)Heating Industry}

^{Primary heat exchangers in gas heating boilers}

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

^{4.General Engineering}

^{Heat exchangers for gas cooling of industrial furnaces}

^{Heat exchangers for tank heating}

^{Oil coolers for vacuum plants, ship plants, pumps etc.}

^{Heat exchangers for oil preheating}
