Failure analysis of high temperature superheater tube (HTS

Boiler tube failure analysis is more complicated than the water main pipe since temperature is involved. In the Figure we can see that the major four causes of boiler tube failure is wear, corrosion, temperature and stress. Wear. Wear, which lead to locally metal loss mechanically seldom comes from the improper installation of boiler which can be avoid by following installation procedure and regularly inspection.

The boiler tubes are under high pressure and/or high-temperature conditions. They are subject to potential degradation by a variety of mechanical and thermal stresses and environmental attack on both the fluid and fireside. Mechanical components can fail due to creep, fatigue, erosion, and corrosion

Dec 01, 2019 · The major problem in all boilers is the failure of boiler tubes that leads to forced outage of them. Several failure mechanisms are known . The causes of failure range from those caused by high temperature to others associated with corrosion factors . Corrosion in steam generator units, particularly in tubes, is mostly influenced by chemistry of water, tubing material susceptibility, operational …
