heat exchanger

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 fin 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.

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. Material: Carbon Steel, Copper Stainless Steel, Alloy, Aluminium

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. Embedded Fin Tubes（G-fin),is considered to have a mechanical bond to the tube and has negligible deterioration of the fin bond with heat cycling. The fin is usually specified for high temperature applications with the fin material being the limiting factor.

Finned tube manufacturers 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.
