Serrated Extruded Heat Exchanger Fin Tube A106 Gr.B

Extruded Fin Tube Product Description:

Murphy has a long experience in production of bimetallic tubes for heat exchangers working in high critical corrosion process, generally applied in Chemical plants, Petrochemical plants and Desalination plants. Outer and Inner tube are in two different materials according to customer design and application needs. They are perfectly tied up to assure a correct heat transfer efficiency.

Sometimes it is necessary that bimetallic tube extremities are entirely made up of the inner tube material to permit a correct tube-to-tube sheet welding. In those case ferrules are required. Murphy has the possibility to provide bimetallic tubes with ferrules already assembled in.

Extruded Finned Tube Manufacturing Process:

The Extruded Fin Tubes are produced by compressing an aluminum tube, or sleeve, onto the base tube. The bloom is exposed to very high pressures which essentially "grows" the fins into the final fin profiles.This process manufacture an excellent strong joint with great resistance (fin stiffness) as well as exceptional heat transfer capabilities (longevity, temperature range). The advantage of extruded fin tubes are full protection of bare tube against corrosion and fin has high mechanical strength. Extruded finned tubes provide the most stable performance over time as compared to the other fin types. The fin is rolled from an outer aluminum tube by a process using pressure to create a rolled "pressure bond" between the liner tube and fins. The aluminum fin material completely encloses the tube, except at the ends where a tube coating can be applied.

Extruded Fin Tubes Advantages:

100% fin-to-tube bond providing exceptional efficiency and longevity.

Excellent corrosion protection on the base tube.

Easy to clean with a high-pressure water jet without deforming the fins.

As the outer sleeve is continuous No galvanic corrosion between the tube and fins.

The bonding of the outer and inner tubes removes the risk of loss of contact with the aluminium due to thermal stress and fins are vibration resistant.

Higher heat transfer performance for the life of the unit.

Extruded Finned tubes are commonly used in applications with temperature up to 325 °c.

Extruded Aluminum Tubing Properties:

High heat transfer performance, low contact resistance;

The fin has a large contact area with the tube, which is close and reliable;

Good corrosion resistance and stable long-term service performance;

The fin has good rigidity and is not easy to deform.

It is widely used in steel, petroleum, chemical, machinery, shipbuilding, power station, hospital and food industries.
