Abstract: In order to take effective measures to avoid the earlier cracks in welded area of high-pressure steam pipes of the 125MW turbine, the stress analysis under high temperature was put into practice. The paper analyzes the causes of cracks based on the experimental data, which is helpful for finding out protective measures in the design.

Key words: high-pressure steam pipe, stress, test, destruction, strain
