Tube Finning Machine




We believe in mutual relationship between us and our clients, as we offer quality and earn satisfaction from the customers' end. We here manufacture and supply Tube Finning Machine adorned with versatility, speed, durability and efficiency you require at the user end. The high end machinery is used to increase heat precipitation efficiency by 5 to 6 times and are also capable of continuous finning. These machines are used to make cooler, thermal fluid heat exchanger and are fabricated from metals like MS, copper, SS & aluminum.

Our clients can avail from us an extensive array of Finned Tubes with a continuous Spiral/'L' Wound Finned Tubes having crimp/'L' fins, which increases the overall heat transfer surface area. a high rate of quicker dissipation and higher heat-transfer coefficient is obtained with the equipments fitted with Fin Tubes. These are paired with continuous spirally crimped/'L' and are made under high mechanical tension bonding process, in which fin material is bound over the tube to get maximum contact of tube & fin and only end of fins are brazed/welded to core tube.

These are used for heat transfer i.e. cooling / heating of :

  • Oils
  • Fluids
  • Water
  • Steam
  • Air Gases
  • Other Vapours


Application Areas :
These tubes are used in Fin Heat Exchangers, Steam Radiators, Autoclaves, Condensers, Dryers, Ovens, Furnaces, Air Heaters, Oil Coolers, After Coolers, and Air Compressors & in many other Heat Transfer Equipments. Fin Tubes are widely used by chemical, Petrochemical, Fertilizer, Food, and Pharmaceutical, Paper, Textile & several other industries.

Construction :

  • Base - M.S. Fabricated with foundation provision and leveling arrangement.
  • Body - Capsule type Roto advancing arrangement of Tube for continuous Tube Finning and mandrel arrangement for manufacturing of Fin Coil. Adjusting for pitch 2.0mm to 12.0mm.
  • Drive - Geared Motor with variable frequency drive to change speed for various sizes of Tubes.
