  • Refinery Problem Events Reformer Heater Tube Failure …

    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. This design would be inherently susceptible to thermal fatigue and …Get Price

    Failures caused by what is commonly referred to as thermal shock are actually fatigue failures caused by thermally induced stress cycling. They are not an indication of boiler design or manufacturing deficiencies, as has been inferred on occasion, but are rather due to the manner in which the heating system has been designed, controlled or operated.Get Price
