3.We manufacture fin tube,heat exchanger,copper tube,,more than 15 years. We are original manufacturer of fin tube and heat exchange
Since 2002 ,we have been in the fin tube and heat exchange field .
Our laser fin tube is our new technology ,we have own patent and brand .
We can produce extruded fin tube ,spiral L ,LL ,KL fin tube ,Embed G type fin tube , U bend tube ,Longitudinal Finned Tube , high frequency welding fin tube ,H ,HH fin tube , Aluminum fin tube ,square fin tube ,low fin tube ,high fin tube ,copper fin tube ,stainless steel fin tube ,carbon steel fin tube , Serrated fin tube , stud fin tube , All these fin tubes can make the fin tube heat exchange or radiator as per customer's request ,welcome you to come to our factory to do the audit and welcome you to contact us to send inquiry .
Laser welding stainless steel finned tube is most advanced and state of the art technologies.The laser-welded finned tubes are manufactured by hectically winding strip onto tubes.The fin strip vertically applied to the tube is welded at its foot by a welding technique developed.We develop a precise tooling and equipped with German made laser welding machine to ensure 100% welding integrity.Advantages:thin,continuous weId seam
;small heat affected zone;short heating time;only slight micro structural change in tube and fin;high utilization of heat for forming the seam;high welding speed;no impurity of the weld seam,as the Laser welding is carried out under a protective atmosphere.Our total length of tube could be 12 meter long, and can be winded in different shape.
These Copper & Copper alloy high finned tube is integrally extended for the maximum surface area to achieve height tube efficiency.A good finned tube can be made by the strict conditions such as copper density, grain size and hardness.The heat transfer ratio of this high finned tube is about 8~9 times higher than other plain copper tube.
Serrated Extruded Heat Exchanger aluminum Fin Tube,A179 seamless Carbon Steel tubes. Advantage:1.The extrusion finning machines are designed and assembled by ourselves and we can offer you finning machines,extrusion muff sleeves and all accessories(extrusion finning disks)etc...2.DR-extruded bimetallic fin tubes maximum operating temperature:300 degree.The transfer coefficient remains steady.3.DR-extruded bimetallic fin tubes have stronger fins than other mechanical fins,like L,LL,KL,and G,so it is much easier to clean.4.In application of high stress and corrosive condition,DR-extruded bimetallic fin tubes provides an excellent technical and economical savings in comparison to a costlier single alloy tube,as the use of costlier material is reduced to the min.
'LL'FINNED TUBE:Manufactured in the same way as the'L'finned tube type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance.This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
L FINNED TUBE:The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maxi mising the heat transfer properties.The foot of the fin considerably enhances the corrosion protection of the base tube.
KL FINNED TUBE:Manufactured exactly as the 'L' finned tube except that the base tube is knurled before application of the fin foot.After application,the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube,resulting in improved heat transfer characteristics.
G'EMBEDDED FINNED TUBE:The fin strip is wound into a machined groove and securely locked into place by back filling with base tube material.This ensures that maximum heat transfer is maintained at high tube metal temperatures.
