Boiler Tube Failure Thermohydraulic Analysis


Boiler Tube FailuresCracking of the boiler tube had occurred by thermal fatigue. The difference in thermal heating/expansion of the surrounding wall plates versus the water-filled boiler tube had applied high thermal strains onto the tube during rapid temperature changes (i.e. starts/stops, TRIPS, operating issues, etc.). Repeated thermal cycling had resulted in the formation of thermal-based corrosion fatigue cracks.Boiler Tube Failure Analysis - Applied Technical ServicesATS' Boiler Tube Failure Analysis Services.
