| Abstract: | It introduces mechanism of stress corrosion craze produced by stainless steel and conditions of possible occurred stress corrosion crazing of stainless steel welded pipe for steamer condenser during usage and points out that pull stress of mental material is to produce the necessary conditions of stress corrosion crazing.The control and prevention measure i.e.to reduce mental material tensile stress,select suitable material,control of media environment and scheduled maintenance to the pipe is put forward aimed to stress corrosion crazing problem produced by stainless steel welded pipe for condenser. |
