Aim To research the impact robustness of internally pressured pipeline. Methods Passes through full scale experiment to imitate the damage of internally pressured pipeline under actual project environment. The acquired test data are analyzed and plotted by computer. Results and Conclusion The experiment on the pressured pipeline under quasi static load has established a theoretic foundation for the analysis. Reliable analytic method and improtant technical parameters are provided for the evaluation of impact robustness of high pressured pipeline with fluid medium and their safety design.
