PWHT of bifurcated pipes (Y-pipe)
PWHT of bifurcated pipes carried out using resistance heat treatment units. To establish a furnace, the outer skin of the component was considered as the furnace wall. The whole component was insulated outside and heated from the inside with four-bank- heaters. The outer sickle was heated separately by means of heating elements.
PWHT on a MP turbine casing
The area of repair was heat treated at full PWHT-temperature. On the remaining area of the casing a basic temperature of 80% was applied. The whole turbine casing was insulated in total to minimize any temperature losses.
PWHT of heat exchangers
THERMOPROZESS is also able to perform PWHT on complex components like heads of heat exchangers.
