G Fin Tube (or Embedded Fin) Finis embedded into the outer wall of the tube, but gives no surface protection. Ingeneral use for continuous process applications; ie refineries, petrochemical,fertilizer and gas plants.

Extruded Fins / Extruded serrated Fins Finned tube is composited with iron-aluminum or copper-aluminum tube rolling out the fin, which feathers are tightness, small heat resistance, good heat transfer performance, high strength, small flow losses, strong corrosion resistant performance, not easy to deformation and a long working lifetime in cold and hot condition,etc. The fin givescomplete protection to the base tube and is much stronger than the applied type due to work hardening of the fin material during the extrusion process.

LL-type finned tube makes the trapezoidal cross-section forming by rolling combine closely with the heat flux density distribution size. The fins combine tightly with the tube,which makes the thermal efficiency higher and put an end to thermal resistance that brings by the non eliminate contact from segment gap of the string type finned tube. 1 Features: The winding technology improves production efficiency and heat transfer, makes the average fin pitch and higher proportion between fins and tube. At the same time, the base tube can be protected from air erosion. 2 Application: LL-type finned tube mainly used in petrochemical, electric power, paper making, tobacco, building heating and other industry such as air cooler, air heater and air heater of food industry, plant starch spray drying system. The fin is wrapped around the tube with an overlapping foot and secured at each end. Gives good surface protection to the tube. Used for moderate temperature coolingapplications. Material: Copper, Carbon Steel, Copper Stainless Steel, Alloy, Aluminium Bare tube OD: 15.88-45mm Fin Pitch: 2.1-5.0mm Fin Height: <16mm

L Fin (or wrapped fin): with metal strip wounded on the core tube The fin is wrapped around the tube and secured at each end. Gives some surface protection to thetube. Used for moderate temperature cooling applications. L-type finned tube mainly used in petrochemical, electric power, paper making, tobacco, building heating and other industry such as air cooler, air heater and air heater of food industry, plant starch spray drying system.

Extruded type: with cold rolled extruded fin Thirteen extrusion fining lines, daily capacity around 9000 meters The extruded fin gives complete protection to the base tube and is much stronger than the applied type due to work hardening of the fin material during the extrusion process.

Low fin tube Low fin tube are mainly used in the condnsers and evaporators for air cooler and refrigerator, absorption refrigerator, oil cooler and other heat exchangers. And other industry such as coal power stations, nuclear power stations，boat heat exchangers, air cooler. Heat recovery system, dryers and heaters in chemical industries.
