Partial stress-relieving annealing on a high-pressure preheater

Components of the most diverse geometry and sizes can be partially heat-treated on site at rational cost using a mobile furnace. Such furnaces are also suitable for use, for example, on tube-sheet welds, circumferential welds to adjacent components, series heat-treatment operations, etc.

The benefits in detail:

• Uniform heat input throughout the component cross-section

• Unrestricted distribution of heating elements
• Individual setting of zone temperatures
• Temperature control via of selection of time and heat input rate
