This paper discusses failures which have occurred in a number of thick-walled pressure vessels including superheater and reheat outlet headers, and med and steam drums in fossil fired boilers. It provides details regarding the causes of failure, which range from original manufacturing defects to service-related deterioration such as creep and thermal fatigue. It also provides information regarding inspection techniques which are capable of detecting similar conditions before they have reached dangerous levels of deterioration. Finally, it provides details pertaining to techniques used to successfully repair these pressure vessels when they have failed.
