Abstract
In this study a nerv experimental method for measuring the ci-eeg of p ipeline using moire interferometry was proposed. Curved-surface-deform ed grating replicating technique as combined with the high-temperature -resistant grating and moire interferometry method, and was applied to measure rite creep of a 475 degrees C main steam pipeline in the Qing he Power Plant for 3600 h. The measuring principle and experimental te chniques are described. The measuring error and experimental results n r-e discussed in detail.
