copper 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.

Copper tubes for heat exchangers after sand blasting, which coud improve the heat transfer performance

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.

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.
