Aluminium Embedded Heat Fins Tube Extruded Type Pipe 304L

Aluminium Extruded Type Pipe Heat Fins Tube

• Fin tube is a kind of heat exchange tube,by adding the fin on the surface of the tube,to increase the outer or inner area of heat tube and improve the heat exchanger efficiency.
• Advantage:Anti-corrosion,anti-wear,lower contact resistance,higher stability,prevent dust,etc.
• Application:Air conditioner,air cooler,boiler,other special application fin tube,etc.
• Fin type:high frequency welding spiral fin tube,suit fin,embedded spiral fin,brazing of spiral finned tube,,overall type three-roll skew rolling spiral fin tube,etc.
