Extruded Finned Tubes
(Bi-Metallic Fin Tubes)
Anand Seamless Ltd. manufactures Extruded Finned Tubes, also known as Bi-Metallic Fin Tubes, using advanced cold extrusion technology. In this process, aluminum or copper fins are integrally extruded over a base tube (carbon steel, alloy steel, stainless steel, etc.) with high mechanical bonding and optimal heat transfer properties.
These tubes offer superior resistance to corrosion, high mechanical strength, and longer operational life due to the complete encapsulation of the base tube. They can also be frequently cleaned using high-pressure jets, which reduces downtime and enhances the life of the cooling systems.
Available in solid or serrated fin profiles, we offer full customization of fin density, height, thickness, and bare ends.

Frequently Asked Questions (FAQs)
Why choose extruded fin tubes over other types?
Extruded fins offer excellent bonding, corrosion protection, and can withstand high-pressure cleaning—ideal for long-term industrial use.
Can these be used in food-grade applications?
Yes. With stainless steel or copper base tubes and aluminium fins, they are suitable for food and agricultural heat exchange systems.
Are serrated fins available?
Yes, we offer both solid and serrated fin types depending on the application.
What’s the maximum working temperature?
Up to 300°C, making them ideal for high-temperature gas cooling systems.
