Heat exchanger tube in a wide range of austenitic stainless steels, duplex stainless steels, nickel, titanium and zirconium alloys, suitable for all types of heat exchangers such as seawater coolers, condensers, evaporators, heaters and repeaters.

Cold Drawn Seamless Tube manufacturers in India make pipes that include both imperial and metric sizes, from 0.472 to 1.575 in (12 mm to 40 mm) outside diameter. Special sizes can be offered upon request. Sandvik heat exchanger tubes are supplied in straight lengths up to 30 meters or as U-tubes.

Lower costs throughout the life cycle with duplex stainless steels

The portfolio of boiler tubes manufacturers in indiaproduce duplex stainless steels is the complete market. Duplex stainless steel heat exchanger tubes perform exceptionally well in various environments and media every day in process industries and reduce costs throughout the life cycle.

An alternative to expensive nickel alloys

One of the most recent developments that stainless steel heat exchanger tube manufacturer produces is hyper-duplex stainless steel, which can be, for example, a very competitive alternative to expensive nickel alloys and high-alloy austenitic stainless steels in the most demanding applications—demanding, such as hot tropical marine environments.

Heat Exchanger U-tubes

The tubes manufactured by Alloy steel boiler tubes manufacturer are by common standards for heat exchangers. Our basic specification is SA 210 Gr A1, but we can also use SA 178 Gr A or various customer specifications. Copies of all specifications are available upon request.

Technical parameters

  • OD 12.7-38mm
  • Radii of curvature of 1.5 x OD at 1250 mm. Minimum bend radii can be agreed for OD greater than 28mm.
  • Min section length 1000mm
  • Section length max. 12,000mm.

Heat treatment

If specified, stainless steel condenser tubes manufacturers in India are prepared to heat treatment of U-tubes with a minimum section of 150 mm.

  • We use a protective atmosphere of argon inside the tubes.
  • We can supply all types of annealing: solution annealing, softening annealing and stabilization.

Measuring, cutting, deburring and cleaning

  • U-tubes are precisely measured according to the relevant standards.
  • All tubes are cut to the specified section length, their ends are deburred, and internally air cleaned.
  • Before packing, both ends of the U-tubes are plugged with plastic caps.


  • In resistant wooden boxes, open or closed, depending on the destination, of 8000 kg max.
  • The ends of the tubes are protected with plastic caps.
  • Vertical separators of each spoke.
  • Chloride-free plastic spacers between each row, every 2 meters.
  • Each package is covered in plastic.
  • Customers can provide a packing plan, or Sandvik can prepare its own.
  • Packing lists, covered with plastic, are inserted into each wooden crate to quickly identify order details, including a list with exact radii and lengths.

Some of the typical applications of heat exchange tubes made by finned tubes manufacturer in India are:

  • chemical processing
  • capacitors
  • Flue gas purification
  • Evaporators
  • feed water heaters
  • gas treatment
  • hydrometallurgy
  • Oil refining, petrochemical processing and gas treatment
  • Phosphoric acid production
  • petrochemical processing
  • salt evaporation
  • Seawater cooled heat exchangers
