Aluminum Extruded Fin Tube ASTM B163 UNS N08825 Nickel Alloy Tube for Oil Cooler
Extruded Finned Tube ASTM B163 Incoloy 825 Nickel Alloy Base Tube with Al Fins
Extruded type finned tubes refer to a type of heat exchanger tubes that have fins extending outward from their surface. These fins are typically created by an extrusion process, where the fins are formed by forcing the material through a shaped die. Extruded finned tubes consist of a base tube and extended fins. Two metals are used to manufacture extruded finned tubes. The outer surface is usually aluminum, while the inner tube is of any material. The base tube is usually made of materials such as copper, stainless steel, carbon steel, or aluminum. The fins, which are integral to the tube, are formed by extruding the material of the base tube. Fin Types: Extruded finned tubes can have different fin types based on the application requirements, including plain, serrated, or low-fin configurations. The fins increase the surface area of the tube, allowing for enhanced heat transfer efficiency.
Why Choose Extruded Finned Tube?
Most of the industries choose extruded fin tubes as they offer a better level of resistance against corrosion. This helps them to be highly durable thus letting you have a strong heat exchanger. Along with this, they can withstand mechanical stress and provide flawless results. It is generally used with industries that do not require the material to reach a very high temperature.
