保压——泄压后处理-漏点? 按工序系统分段来进行气密性试验。如发现漏气处,做好标记,泄压后处理。消除泄露点缺陷后,再升到规定压力重新检漏,直到找不到漏点。待系统压力温度平衡后,保压一小时,压力不降为合格。 the system should be leak tested on separate process sections. if any leaks are indentified, mark the leaking points and eliminate them after depressuring. after all leaking points have been eliminated, pressure up the system to the specified level and retest it till no leak is identified. when the temperature and pressure of the system remain stable, hold the pressure for one hour untill there is no pressure loss. 查看更多
