| 摘 要： | 法兰连接中螺栓的预紧力,要满足法兰接头在操作时不发生泄露。叙述了螺栓从预紧状态到操作状态过程中法兰接头的变化。预紧力应是考虑了内压作用和垫片在升压过程中松弛的综合结果。

| Abstract: | The pre-tightness force of bolts in flange connection must meet the requirement, that is, flange tie-in can not leak when operating. The thesis states the change of flange tie-in from pre-tightness to operating. The pre-tightness force is the result of the internal pressure action and gaskets loosing during the pressure-rising course. |
