摘要

Cold Reheat Piping has received little attention in power plants for many years. Carbon Steel piping that handles steam at 500 F to 600 F has only had problems when not properly supported or water hammered on start up. Most recorded failures have been mechanical fatigue at a girth weld.rnA number of catastrophic failures in Cold Reheat Piping have occurred in recent years. Most of these recent failures can be traced back to water hammer or a change in the operation of attemperator sprays.rnThis paper shows how a Cold Reheat Piping system, that was included in a nondestructive test program, failed in a short period of time due to thermal fatigue, from a change in spray operation.
