Annealing heat exchangers is a special craft. Smit Heat Treatment has developed a unique method for this purpose, which only requires one treatment to anneal the entire heat exchanger.

Annealing heat exchangers without deformation

Over the years, Smit Glühdienst GmbH has specialised in the annealing of heat exchangers, whereby the tube bundle is already in the sleeve and the tubes of the heat exchanger are welded to the tube sheet. Annealing with this system, developed in-house by Smit Heat Treatment, prevents deformation of the tube bundle due to stretching and shocking during the heating and cooling phase.

Annealing heat exchangers with just one annealing treatment

Annealing with Smit Heat Treatment’s in-house developed system has a number of advantages:

  • Only one annealing treatment is required to anneal the entire heat exchanger with low stress
  • Optimum yield
  • Power consumption is extremely low
