The finned tube provide by us is Extruded Type, which is different from the ones through HF Welding and Wrapping method. The fins are obtained by roll forming the outer surface of a soft seamless plain tube. The technology simply squeezes the wall thickness transforming into straight fins on the tube. So the fin and the tube are integrated and inseparable, which avoids the heat resistance between fin and tube, and optimizes heat exchange efficiency. Based on this structure, the Extruded type can survive more severe working conditions than other finned tubes. Also it, on the other hand, shows several unique features such as enhanced physical structure, resistance to vibration, anti-corrosion ability, and long service life, etc.

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°

Material: Aluminum, Copper, Carbon Steel, Alloy.etc.

Bare tube OD: 8-51mm Fin Pitch: 1.6-10mm Fin Height: <17mm Fin Thick: 0.2~ 0.4mm

Application: mainly used in petrochemical, electric power, paper making, building heating and other industry such as air cooler, air heater and air heater of food industry, plant starch spray drying system.

Capacity: Thirteen extrusion fining lines, daily capacity around 4000 meters


Products&Inspection Deatails:


Visual inspection for the tube












Following documentations should be reviewed & endorsed:
Incoming inspection report for raw material including bare tube/alu.tube / alu. strip / steel strip
Mill test cetification for bare tube
Mill test cetification for fin (alu.tube / alu. strip / steel strip)
Mill test cetification for finned tube
Finned tubes dimension & visual inspection reports

Packaging: sea worthy with plastic cap for each edge of core tube , finned tubes shall be put on the metal frame with wooden walls and plastic layer be considered between tubes rows to avoid damage and deformation of the fins
