Special annealing furnaces were integrated into the portfolio of ALD France by the merger of FNAG with TIV to ALD France.

This includes  the design and construction of the world largest heat treatment vacuum furnace for annealing induction coil (D-coild) for the nuclear fusion project ITER.

Main products of ALD France are customized vacuum annealing furnaces for the heat treatment of long tubes up to 30 meters. Typical applications are annealing of steam generator tubes or nuclear fuel rods. 

Key features

  • Tube length up to 31 m
  • Pressure less than 10-4 mbar
  • Temperatures up to 1100 °C
  • Temperature uniformity ± 5°C
