Heat Exchanger Tubes

Fine Tubes offer a range of products specifically meeting the demands and specifications required in the fabrication of shell and tube heat exchangers. We design and manufacture tubes for the HX market that fully meet the requirements in terms of price, delivery and specifications.

Our heat exchanger tubes are used for the cooling, heating or re-heating of fluids, gases, or air in a wide range of industries, such as chemical processing, hydro carbon processing and oil refining, nuclear power generation and aerospace.

Fine Tubes heat exchanger products can be purchased as seamless, welded or welded redrawn tubes in the following materials:

  • Nickel alloys
  • Austenitic stainless steels
  • Duplex
  • Super Duplex
  • Super Alloys

These high performance tubes are available at dimensions between 12.70 mm and 38.10mm OD, which covers the majority of the standard sizes used. However, Fine Tubes also specializes in the development and production of small diameter thin wall tubing associated with applications in the aerospace and nuclear industries. Our minimum size here is just 0.98mm OD with a 0.04mm wall thickness.
