这种容器的最大优点是在绕制过程中获得高预压缩应力，显著减少疲劳失效的危险性。
A tremendous advantage of these vessels is that high compressive stresses are induced during winding. This Prestressing greatly reduces the risk of fatigue failure.
去除焊缝余高或将焊缝设计在最大剪应力平面内可明显改善对焊接头的疲劳性能。
The fatigue resistance of the butt welds can be improved by means of removing the weld reinforcement and designing the weld in the maximum shear stress plane.
当高角度缝的走向与最大水平主应力的方向一致时，后期水平应力对原生裂缝有保持作用；
When the high-angle fracture has the same direction with the maximum horizontal stress, the subsequent horizontal stress will preserve the primary fracture.
