SS304 Tube with Grooved Fin Fabrication
The fin material aluminum strip is wound into the previous machined groove and then securely locked at the place by back filling with the SS304 Tube material.

Package
The finished fin tubes will be supplied with plastic caps at tube ends, then packaged in strong seaworthy wooden boxes with steel frame.
Advantage
Comparing with extruded fin tubes, the grooved fin tube ensures that maximum heat transfer is maintained at high tube metal temperatures with lower cost.
Weight lower than extruded fin tube, so can decrease the weight of whole air cooled heat exchanger after installed with fin tube bundles.
High heating efficiency, small volume, low resistance of wind and easy to install.
SS304/ 304L Fin Tubes offer high tensile strength, corrosion and abrasion resistance, and have long functional life to extend the lifetime for the whole air cooled heat exchanger.
SS304 Tube with grooved fin are used in various industrial applications such as boiler economizer, power plant, wast heat boiler, petrochemical and chemical engineering, refinery plant and air fin fan coolers.
