Stress and Integrity Analysis of Steam Superheater Tubes

2004-5-26 · contaminated water, coming from the drum, flows through the superheater (internal) after some process abnormality. This causes increased stress in a tube operating at a con-stant internal pressure. In addition, corrosion is a source for overheating problems, by the formation of an oxide layer, which is a barrier to heat transfer.
