Heat treatment for stress relief

We have portable burners for field execution of heat treatment for stress relief, in the most varied pressure vessels of the petrochemical industry:

  • Catalytic reactors
  • Low-temperature reactors in sulfuric acid plants
  • Ammonia plants
  • Hydrogen units and equipment
  • Units and equipment of sulphur
  • Risers
  • Combustion chambers
  • Boilers, among others

In these activities, we dimension and apply the necessary insulation and monitor the temperatures of critical points, throughout the execution of the thermal cycle, following the applicable standards.

We also carry out the programming and execution of moving supporters or the equipment itself, accompanying its pace of expansion.

We operate with combustion sets of high thermal load, which give a slightly positive pressure to the equipment.

We develop tailor-made solutions for equipment of all sizes.
