Extruded And Serrated Type Finned Tube

What are extruded and serrated finned tubes?

Extruded serrated finned tubes are a specific type of heat transfer tubes that combine the features of both extruded finned tubes and serrated finned tubes. These tubes are manufactured by applying a serrated pattern onto the surface of a base tube using an extrusion process.

The extrusion process involves forcing a metal, typically aluminum or copper, through a specially designed die. The die creates the desired serrated pattern on the surface of the base tube. This process ensures a strong bond between the fin and the base tube, resulting in a durable and efficient heat transfer surface.

The serrated pattern on the fins of these tubes serves to increase the surface area, which enhances heat transfer efficiency. The serrations create turbulence in the fluid flow, promoting better heat transfer between the fluid inside the tube and the surrounding environment. This makes extruded serrated finned tubes suitable for applications that require high heat transfer rates.

Extruded serrated finned tubes are commonly used in various industrial heat exchangers, such as air-cooled heat exchangers, condensers, and boilers. They are particularly effective in applications involving high temperatures or where there is a significant temperature difference between the fluid inside the tube and the ambient environment.

By combining the benefits of extruded fins and serrated patterns, these tubes provide improved heat transfer performance and are a popular choice in industries that require efficient heat exchange processes.
