The low fin tube is also known as “integral Fin Tube”. This types of fin tube is widely being used in the industry today.
The low fin tubes / Integral Fin Tubes are increasingly being used in various fluid heat exchangers.
Unlike other fin tubes the application is not limited to air-fluid type of heat exchangers. As a result they are used in various types of shell and tube type heat exchangers also. The fins are manufactured by rolling the fin in the base tube itself. The fin height is relatively very low.
However number of fins per inch or the fin density can be increased greatly and improve heat transfer area. The rolling is done on a special machine and the same can be supplied in straight as well as ‘U’ bend configurations.
This fin tubes find application in AIR-FIN COOLERS, DRIERS, RADIATORS etc. and are used in industries like power plants, Gas plants, chemical industries, steel plants, chiller plants, petroleum refiners, food & Agriculture equiptments.
Properties of LOW FIN / INTEGRAL TUBES
| Property | Description |

| Fin to Tube Bond | NA (Fin is extruded from the base tube itself) |
| Heat Transfer Efficiency | Good |
| Mechanical Resistance | Good |
| Corrosion Protection | Depending on properties of material of Fin and pipe. |
| Temperature Range | Depending on properties of material of Fin and pipe. |
