Fin Tubes

Tube Tech manufactures Integral Finned Tubes with superior dimensional control in Copper, Brass and Cupro Nickel tube materials for a wide variety of heat transfer applications. Our facilities are capable of producing all types of integral low / medium and high fin tubes to suit every customer’s specific requirements. These tubes are fabricated in alloy C 12200 to meet the chemical, mechanical and other test parameters of ASTM B 75 / B 359 and in alloy 44300 / 68700 / 70600 & 71500 to meet the chemical, mechanical and other test parameters of ASTM B 111 / B 359. BS EN, JIS and DIN standards are also available on request.

• Integral low / medium / high fin tubes with fin density other than mentioned in the above chart can be produced on request.
• For tube parameters of medium and high fin tubes of any size between 12.7 mm outer diameter to 25.4 mm outer diameter, please contact us.
• Integral Fin Tubes are generally supplied in the “as finned” condition. Brass Tubes and Cupro Nickel Tubes can be supplied in “annealed” temper upon specific request.
• Integral Fin Tubes are generally produced with desired plain ends, tubes can also be fabricated with intermediate landings upon specific request.
• Integral Fin Tubes are produced in straight length up to 8 Meters. Bigger lengths can be accommodated on request.

End Application :  Heat exchangers, air condensers and air preheaters, Oil Coolers, process coolers, refrigerant evaporators etc.

End cross fin tube is a tube having integral external fins of 26 to 40 fins per inch and increased fin height with a trapezoidal shape. These fin tubes are produced with smooth bore as well as integral internal ridges. End Cross Fin Tubes are generally used in Vapour Absorption Chillers. These fin tubes are available in 12.7 mm, 15.87 mm & 19.05 mm outer diameters with wall thickness as low as 0.55 mm. These fin tubes can be fabricated from all types of Copper & Copper Alloy Tube products. It is also known as Knurled Fin Tube.

● End Cross fin tubes with Tube Dia and fin density other than mentioned above can

be produced on request.

● End Cross fin Tubes are generally supplied in the “as finned” condition. However,

Brass and Cupro Nickel End Cross Fin Tubes can be supplied in “annealed” temper

upon specific request.

● End Cross Fin Tubes are generally produced with desired plain ends, tubes can also

be fabricated with intermediate landings upon specific request.

● End Cross Tubes are produced in straight length up to 8 Meters. Bigger lengths can

be accommodated on request.

Integral Low Fin Tubes with finely grooved, modified outer and internal enhancements are produced by Tube Tech for Refrigerant Condenser Applications. These fin tubes are manufactured with integral helical fins on the outside surface of the tube which enhance the condensing heat transfer coefficient. Internal helical ridges of this enhanced condenser tube act to induce turbulent water flow and increase surface area, both of which improve heat transfer. These fin tubes are ideally suitable for demanding condensing applications. These fin tubes are fabricated in alloy C 12200 to meet the chemical, mechanical and other test parameters of ASTM B 75 / B 359 and in alloy 70600 to meet the chemical, mechanical and other test parameters of ASTM B 111 / B 359. BS EN, JIS and DIN standards are also available on request. 

 Condenser Fin Tubes are generally produced with internal ridges / rifles. However, smooth bore tubes may also be produced on request.

 Condenser Fin Tubes are generally supplied in the “as finned” condition. However, alloy 70600 can be supplied in “annealed” temper upon specific request.

 Condenser Fin Tubes are generally produced with desired plain ends, tubes can also be fabricated with intermediate landings upon specific request.

 Condenser Fin Tubes are produced in straight length up to 8 Meters. Bigger lengths can be accommodated on request.

 Condenser Fin Tubes are supplied with deburred / smooth ends.

End Application: Refrigerant condenser applications

Tube-Tech manufactures internally finned tubes / internally enhanced tubes with

a plain outer diameter and 50 to 70 internal ridges as per the requirement of the

Customer for Direct Expansion Shell and Tube Liquid Coolers. These inner grooved

tubes are also called Dx Tubes Or Evaporator Tubes. These internally enhanced fin

tubes are designed to provide maximum heat transfer with minimum refrigerant side

pressure drop. The inside heat transfer coefficient of these tubes is generally 2 to 3

times greater than coefficient for smooth surface tubes. These internally finned tubes

are available in tube materials Copper UNS C 12200 & 90/10 Cupro Nickel UNS C 70600.

● Internally Finned tubes with wall thickness and internal ridge density other than

mentioned above can be produced on request.

● Internally Finned tubes are produced in straight length up to 6 Meters. Bigger

lengths can be accommodated on request.

Tube Tech is well equipped to manufacture integral finned U - Bent tubes, fabricated according to various heat exchanger standards or to customer's own specifications. We generally produce Finned U Bent Tubes in outer diameters 15.9 mm & 19.05 mm with wall thickness 1.32 mm and above. However, bigger sizes can also be accommodated on request. Bending radius of 1.25 X Diameter and above can be achieved on these integrally finned tubes. The Bend portion is left unfinned during finning operation to accommodate bending operation. The Finned U Tubes are produced, controlled and measured in accordance with SB 395 & TEMA standards.

We are capable of producing Finned U Bent Tubes in the Leg Length of up to 5 mtrs. These Finned U Tubes are hydro tested after fabrication against any surface defects / leakages. We have in house stress relieving facility and these tubes can be heat treated for stress relieving, if required by the Customer. All tubes are cut to the specified leg lenght, ends deburred and the bores are internally cleaned with dried air before final inspection & packing. Each bundle is protected with plastic sheets. Detailed packing lists are attached to boxes to give quick and clear identification of contents.

Tube-Tech manufactures finned Cooling coils in various forms and shapes for direct applications in different types of heat exchangers. These cooling coils are manufactured mainly from Copper Tubes, Cupro Nickel Tubes and Stainless Steel Tube materials. Medium and High Fin Tubes are produced in Fin Density of 11 Fins per inch and Fin Depth of 2.5 mm and above in straight lengths. These finned tubes are then formed in the required shape generally helical to suit the Customer’s specific requirements. We also customize these cooling coils in our in house design facility as per the Customer’s requirements for different applications. These cooling coils exhibit high thermal conductivity and are compact in design and thus save cost and assembling space.

These Finned Cooling Coils are available in 15.9 mm & 19.05 mm base tube diameter. These Finned Cooling Coils are available in single layer wound OR double-layer wound as per the requirement.
