Instrumentation Tubes
Instrumentation tubing is deployed in the nuclear and turbine islands of nuclear reactors and encases equipment monitoring various parameters such as pressure and temperature.

Nuclear Fuel Tubes (Cans)
We manufacture nuclear fuel tubes (cans) in stainless steel (20/25Nb) in seamless form. Deployed in the fuel cans of Advanced Gas-cooled Reactors, our tubes withstand extreme heat, pressure and radiation.

Heat Exchanger Tubes
Fine Tubes supplies thin wall heat exchanger products in Nickel alloys, Duplex and Super duplex as seamless, welded or welded redrawn form.

Condenser Tubes
Fine Tubes has the flexibility to produce thin wall condenser tubing in seamless, welded and welded redrawn formats in the following grades:

  • Titanium (Ti CP Grade 2) in seamless only
  • Duplex (S31803)

Cooling Tubes
We supply seamless stainless steel stator bars used for water and hydrogen cooling in generators within the turbine island.

Nuclear Tubing Quality

  • RCC-M
  • Nadcap (Heat Treatment, NDT, Fusion Welding)
  • 97/23/EC (PED) - TüV
  • ISO 9001 / AS EN 9100
