Extruded fin tubes for heat exchanger , Copper Nickel
Base tube material: (C7060T)SMLS 21.4mmOD*1.2mmTHK*1690mmLG
Fin Material: AL1060; OD41.27mm X 10FPIX 0.3 mm THK
Manufacturing Process:
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.
Uppertemperature limit: 350°
Reference Drawing :
Material: Aluminum, Copper, Carbon Steel, Alloy.etc.
