Penstock pipe belongs to special pressure equipment, which has the risk of explosion. Therefore, it is necessary to strengthen the analysis of common accident damage forms and causes of penstock pipe, and do a good job in quality inspection to ensure the safe operation of penstock pipe. This paper mainly studies the penstock pipe of hydraulic storage power station. In the two kinds of steel, the more suitable steel structure is selected by semi elliptical crack analysis and FAD evaluation. According to the experimental data, steel B is more suitable for this structure. Because the failure time of the material, we make thickness correction with MATLAB. Finally, according to the analysis results, it is more appropriate to select steel B as the material of the penstock.
