A REVIEW OF CORROSION FAILURE AND ITS PREVENTION OF STEAM GENERATOR''''S TUBINGS UNDER HIGH-TEMPERATURE AND HIGH-PRESSURE WATER
|
Abstract:
The failure types of steam generators' tubings working under the high temperautre,high pressure and high purity water were analyzed,including wastage,denting,fretting,IGSCC(Intragranular stress corrosion cracking),PWSCC(primary water stress corrosion cracking) etc and the relevant causes were briefly discussed.The mechanism of SCC(stress corrosion cracking),a kind of severe EACs(environmentally assisted crackings),were particularly reviewed,because of its severity in steam generator's tubings.Meanwhile,some kinds of methods to suppress the initiation and propagation of steam generator's SCC were discussed,especially,the use of inhibitors.
