| Abstract: | Failure samples of tee and flange were examined by using microscope, SEM, XPS, micro\|hardness meter and ferromagnetic meter. The results showed that the crack of tee and flange were attributed to the hydrogen induced crack (HIC), and the samples were sensitive to chloride stress corrosion crack. In the case of environment with high H 2 pressures, hydrogen was the main factor, and work hardening and increasing in stress and hardness at weld zone were inducing factors for the crack of tee and flange. The protective measures are proposed. |
