G Fin Tube (or Embedded Fin): with metal strip embedded in the core tube groove. 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.

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 the tube. 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.

Finned tube is composited with iron-aluminum or copper-aluminum tube rolling out the fin; The fin gives complete protection to the base tube and is much stronger than other applied type due to work hardening of the fin material during the extrusion process. Uppertemperature limit: 350° Material: Aluminum, Copper, Carbon Steel, Alloy.etc. ASTM A106/A53,ASTM/ASME SA210,ASTM A213,ASTM A179/A192 Bare tube OD: 8-38mm Fin Pitch: 2.0-10mm Fin Height: <17mm Fin Thick: 0.4mm (fin top) Capacity: Thirteen extrusion fining lines, daily capacity around 10000 meters

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.

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.

KL type: with metal strip wounded on the core tube with knurled surface. The Knurled Footed Fin is characterized as adding increased tube and fin surface area due to the knurled surface on the fin foot and tube. KL-type finned tube mainly used in petrochemical, electric power, paper making, tobacco, building heating ; Four wrapped fining lines, daily capacity around 1000 meters

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.
