11 finned tubes.jpg

Carbon steel-aluminum composite extruded fin tube, with tube material SA179, SA789, SA214, SA213, SA336

Fin material aluminum, fin thickness 0.25mm~0.8mm, fin pitch 2.3mm~4.5mm, Fin type: Extruded, extruded serrated, any length, used for large air-cooler, heat exchanger, dryer, with high heat transfer and energy conversation.

The parameters and performance are as follows:
1: Technical parameters: The high degree of fin 0-16mm (or outside diameter of fin φ 38.1-φ77m); Pitch of fins 2.3-12mm; Length of finning tube 0.5~ 14m.
2: Single metal rolling finning tube: Pure aluminum 1060 or aluminum alloy 6063.
3: Double metal rolling finning tube: Tube-based protection from the outer layer of aluminum tubes, corrosion-resistant; Tube-based can be made from carbon steel pipe, in addition to, stainless steel tube and copper tube can also be used, as well as titanium alloy tube.
