What is Mono-aluminum finned tubes?
Mono-aluminum finned tubes is one piece extruded finned tubes, without any inner tubes. Mono-aluminum finned tubes are rolled from aluminum tubes as a whole.
Mono-aluminum finned tubes usages
Mono-aluminum finned tubes use for specific application such viscous fluid cooling, heat recovery with heat pipes or for application where weight might be an issue (very light heat exchanger with full aluminum construction).
Mono-aluminum finned tubes produce standard
ASTM B404/B404M is a standard specification published by ASTM International. It outlines the requirements for aluminum and aluminum-alloy seamless condenser and heat-exchanger tubes with integral fins.

Mono-aluminum finned tube is a heat exchange element that increases its heat exchange area by adding fins to the aluminum base tube. It usually adopts the form of base tube sleeve aluminum tube, and the fins are formed by machine extrusion. The base of the fin fits tightly with the outer wall of the tube, and has a high heat transfer coefficient and excellent heat transfer performance.
Mono-aluminum finned tube structure and manufacturing process
The basic structure of the single aluminum fin tube includes an aluminum base tube and a fin formed by an extrusion process. This structure makes the fin fit tightly with the outer wall of the base tube, reducing the contact thermal resistance and improving the heat transfer efficiency.
Application field of Mono-aluminum finned tube
Mono-aluminum finned tube is widely used in various occasions requiring efficient heat exchange, such as drying processes in the fields of chemical industry, machinery, textile printing and dyeing, chemical fiber, metallurgy, coating, wood, etc. It can effectively heat the air, and has the characteristics of smoothness, not easy to dust and scale, and easy to clean and maintain.
Mono-aluminum fin tube is also commonly used in civil and industrial heating, with the advantages of light weight, easy installation and maintenance, and economic energy saving.
