Extruded Finned Tubes

Thermal Equipments, Ahmedabad, offers Extruded Finned Tubes, which provide the greatest resistance to atmospheric corrosion. The aluminium fin material completely encloses the tube, except at the ends where a tube coating can be applied. Where atmospheric corrosion is present and when operated within design temperature limits, extruded finned tubes provide the most stable performance over time as compared to the other fin types. The fin is rolled from an outer aluminium tube by a process using pressure to create a rolled "pressure bond" between the liner tube and fins. Main advantages: 100% fin to tube bonding gives excellent heat transfer; excellent galvanic corrosion protection on the base tube; easy to clean with a high pressure water jet; high heat transfer performance for the life of the tube; and maximum temperature 325°C. Tube sizes: diameter of base tube is 15.87 mm (5/8”) to 50.8 mm (2.0”); fin tube outer diameter: 25.4 mm (1.0”) to 88 mm (3.5”); material of base tube –steel/copper/aluminium/titanium/brass; fin material – aluminium and copper; fin thickness – 0.30 mm to 1 mm; fin height – 16 mm maximum; fin pitch – 8 to 11 fins per inch. The company also manufactures spiral fin tubes, fin tube/shell and tube heat exchangers, industrial fans and blowers.
