水道的连接应衬有密封垫片。所有连接面都不应有应力。
Use sealed gasket in the water path. There isn't stress on all link surface.
刚开始加载时，最大应力集中在搭接面以下的一个三角形区域内。
At the beginning of loading, the major principal stress centralize in a triangle area under the lap.
而随着矿井采掘深度不断加大，其直接面临的“三高”问题，即高水压、高瓦斯、高地应力问题日益突显。
It is straightly faced with the high water pressure, the high gas and stress along with the mining depth increasing continuously, which is increasingly outstanding.
然而，在小曲率半径井中，ESP设备的法兰连接面要承受巨大的弯曲应力，设备受损几率增加，ESP系统的稳定性降低。
However, in these tight-radius wellbores the bolted flanges connecting ESP system components are subjected to extra stress, resulting in potential equipment damage.
