Extruded Aluminum Fin Tubes Manufacturer & Supplier in India
Extruded aluminum fin tubes are used in air-cooled heat exchangers, air preheaters, refineries, power generation and refrigeration systems where increased external surface area is required for air-side heat transfer. They are available in monometallic and bimetallic configurations, including aluminium fins over carbon-steel, alloy-steel or stainless-steel base tubes where specified. The sleeve is mechanically extruded over the base tube to create close fin-to-tube contact. Fin height, fin pitch, tube diameter, wall thickness and length can be selected for the required duty. These extruded aluminium fin tubes are supplied for industrial heat-transfer applications in India. Amardeep Steel is one of the most trusted manufacturers and suppliers of Extruded Aluminum Fin Tubes and other material also in different part of the indian and world also.

Frequently Asked Questions
What are Extruded Aluminum Fin Tubes?
Extruded Aluminum Fin Tubes are heat-transfer tubes with aluminum fins formed around the base tube to increase the external surface area and improve heat transfer.
What is the difference between monometallic and bimetallic Extruded Aluminum Fin Tubes?
Monometallic tubes use aluminum for both the tube and fins, while bimetallic tubes combine an aluminum fin sleeve with a different base tube material.
Are Extruded Aluminum Fin Tubes suitable for high-temperature applications?
Yes,they can be used in elevated-temperature heat-transfer duties within the verified operating limit for the selected aluminium alloy, base tube and construction.
What is the maximum operating temperature of Extruded Aluminum Fin Tubes?
The maximum operating temperature varies by construction and aluminum alloy; around 300°C is commonly considered a practical upper range for many extruded aluminum fin tube applications.
Are Extruded Aluminum Fin Tubes corrosion resistant?
Yes, aluminum fins provide good resistance to atmospheric corrosion, while the selected base tube material determines the overall corrosion resistance.
Do Extruded Aluminum Fin Tubes provide better heat transfer?
Yes, their increased fin surface area improves heat transfer compared with a bare tube, making them effective for air-side heat-transfer applications.
