The performance of a new pressure-relief structure in non-refillable steel welded industry cylinder is evaluated. Instead of a rupture disc welded on the opening of the head, this new pressure-relief structure uses a circular groove which is pressed by a special mold on the dished head. This structure not only avoids opening on the head but also reduces the manufacture cost. To ensure the safety of this pressure-relief structure, the study includes the material tests, tensile tests, hardness tests and burst tests, the limited pressure prediction are carried on. Based on the experimental data and finite element analysis results, an empirical correlation between the limited pressure and the groove pressure is proposed. Furthermore, a probabilistic analysis is performed for the limited pressure.
