Extruded Finned Tubes Manufacturer and Supplier in India
When high heat transfer efficiency and long service life are required, Extruded Finned Tubes are a preferred choice for industrial heat exchangers. They are produced by mechanical 'sleaving' over the base tube, forming one integral fin structure that provides excellent fin to tube bonding and full coverage of the parent tube. This design enhances thermal efficiency and also offers great protection from corrosion and mechanical damage. The extruded finned tubes can be used at temperatures of up to 290°C and are manufactured with tubes based on carbon steel, stainless steel, copper, copper alloys, titanium and other
alloys. They are very durable and suitable for use as air coolers, condensers, economizers, power plants and petroleum industries. Amardeep Steel offers trustworthy Extruded Finned Tubes manufacturer and supplier in India with precision engineered Extruded Finned Tubes in standard and custom specification which are in accordance with international quality standard.

Frequently Asked Questions
1. What are Extruded Fin Tubes?
Extruded Fin Tubes are heat exchanger tubes with integral aluminium fins mechanically extruded over a base tube to provide high heat transfer efficiency and strong fin-to-tube bonding.
2. What are Extruded Fin Tubes used for?
They are used in air coolers, condensers, economizers, boilers, HVAC systems, power plants, and industrial heat exchangers.
3. Are Extruded Fin Tubes corrosion resistant?
Yes. The extruded aluminium sleeve completely covers the base tube, providing excellent protection against corrosion and mechanical damage.
4. What is the difference between single-metal and bi-metal Extruded Fin Tubes?
Single-metal Extruded Fin Tubes are made from one material, while bi-metal Extruded Fin Tubes use an aluminium outer sleeve extruded over a different base tube material for improved strength and corrosion resistance.
5. Can Extruded Fin Tubes be customized?
Yes. They can be customized in terms of base tube material, fin dimensions, fin density, tube length, and overall specifications to meet specific application requirements.
