DELLOK C44300 AL1060 Embedded Finned Tube For Heat Exchanger

About Us

^{Dellok(YONGHUI Radiating Pipe Manufacturing Co.,Ltd) was established in 2002, which is located in Nanjing, China.We joined HARBIN AIR CONDITIONING CO., LTD. in 2022 and became the most professional industry manufacturer in 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.}

^{Product Description}

^{Fin Tube the fin strip is wound into a machined groove on the tube surface and securely locked into place by back filling with base tube material.Also named imbedded fin tube.G fin tube have exceptional heat transfer efficiency at higher tube metal temperature.}

^{Maximum working temperature:750 degrees Fahrenheit (400 Degree Celsius )}

^{G Finned Tube Manufacturing Process}

^{Fin strip is rolled in a uniform taper, helically wound into a plowed groove into the tube wall}

^{and simultaneously backfilled (by flat rotating discs) on both sides to lock the fin to the tube.}

^{No tube material is removed. This gives an excellent bond with high pull out loads.}

^{Fin Material: Aluminium/Copper/Carbon Steel.}

^{Core Tube Material: Carbon Steel/ Carbon Alloy Steel/Stainless Steel/ Nickel Alloys/Copper/Copper Alloys.}

G Finned Tube Advantages

^{High fin stability, excellent heat transfer, high operating temperature.}

^{The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 450°C.}

^{The fin is set throughout its length and consequently does not unwind even when partially uprooted.}

^{This kind of finned tube is one of optimum choices for having good effectiveness/cost ratio.}

^{G Finned Tube Properties}

^{Core Tube: Carbon steels (ASTM A 179/ A 214, St 35.8,etc.), low-alloy steels, stainless steels, copper-nickel alloys, aluminum bronze, copper, nickel-alloys(Alloy 400, ext.),}

^{Fins:Aluminum ASTM B209 Al 1060;ASTM B209 Al 1100, A1050, etc.}

^{Maximum operating temperature for this fin type is 450°C.}

^{G type embedded fin tubes machine is designed based on international advanced technologies and experience with stable and firm slotting embedding technology, pulled off force not less than 70 N, medium allowable temperature of 450 ℃, with strong resistant and heat-resistant ability, widely used in the impact of petrochemical refining air condenser.}

^{G Finned Tube Applications}

^{the petroleum, chemical and petrochemical industries}

^{natural gas treatment}

^{the steel industry: blast furnace and converter systems}

^{power generation: steam turbine exhaust condensing contact condensing with cooling of circulating condensate fossil and nuclear power plants}

^{air conditioning (Freon, ammonia, propane)}

^{incineration of household refuse}

^{compressor coolers, etc.}

^FAQ

^{1. What is a fin tube?}

^{Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube.}

^{2. Where are Fine Tubes products used?}

^{Our main markets include the aerospace, oil and gas, nuclear, power generation, chemical process and medical device industries. However we are also developing products for emerging sectors like desalination, geothermal energy, sports and the automotive industry. We are continually innovating, so if you require tubing for other applications please get in touch and we’ll be happy to discuss your requirements.}
