Natasha Fin Tubes Private Limited

• Tough design
• Prevent leakage
• Easier to align

• Corrosion resistance
• Precision design
• Accurate dimension

• The Integral Fin Tubes is a tube where the external surface of the tube is enhanced by the process of finning and fins are drawn from the base material of the tube, resulting to increase in the surface area by 2.5 times than the plain tube area. The Extruded surface achieved through our manufacturing process is real and uniform.

• Fin Tubes are fully integrated so that the Heat Transfer, performance, life and resistance to vibration are excellent. Fin Tubes can improve the thermal performance of a Heat Exchanger without changing in Shell size, Flow Arrangement and Repositioning of tubing. Integral Low Fin Tubes have a very large Heat Transfer ratio thus it is possible to reduce the volume, weight of the Heat Exchangers and finally reduce the cost.

• Unit Length 3m, 6m, 12m, 18m, 20m

• Number of Fins Per Inch 11, 16, 19, 23, 26, & 30. FPI, as per customer Requirement
• Outside Diameter 9.52mm to 38.10mm

• Tube Wall Thickness 0.55mm onwards

• Integral Fin Tubes can be used in various Heat Exchanger Applications, Viz. Condensers, Chillers, Oil Coolers and Shell & Tube type Heat Exchangers, etc.

The ‘Low Fin Tube’ is also known as Integral Fin Tube. This type 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 heat exchanger also.

The fins are manufactured 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 the heat transfer area. The rolling is done on a special machine and the same can be supplied in straight as well as U bend configuration.

• Low maintenance
• Persistent against rust
• Light weight

• NFT is having an in-house tube bending facility for manufacturing Finned "U" Bend Tubes for Heat Exchangers. Bending of "U" tubes as per TEMA-RCB (Sec. IV).
• Tolerances of Fin Tubes are strictly maintained as per customer requirement and inspection will be carried out as per Quality Plan, The Dimensions are checked by Testing and Measuring Equipment and Profile of the fins are checked on Profile Projector. 100% Fin Tubes are checked for leak test by Pneumatic Pressure
• Testing / Hydro testing as per specification and requirement.
• NFT is having an in-house Continuous Conveyor Type Furnace for Stress Relieving of Non-Ferrous material, after finning. Hardness and Microstructures are confirmed and verified after Stress Relieving
• Fin Tubes can be offered for any Third Party Inspection Agency for inspection as per the customer's requirements.

• Design As per ASTM SB-359, SA-213/SA-213M, SA-450/SA-450-M, SA-688/ SA-688-M
• Material Stainless Steel, Carbon Steel, Galvanized Iron, Aluminium
• Material Testing as per ASTM B-154
