Pressure shall be boosted smoothly and slowly, and pressure boosting speed shall not exceed 0.294MPa/min。When boosting pressure to 2.4Mpa, stop boosting pressure, and make rough check for the system. If no abnormality found, continue boosting pressure until working pressure of boiler drum reaches 18.59Mpa, stop boosting pressure for full check to the system. If no abnormality found after the check, overpressure test may be done after directed for boosting pressure by test leader. When overpressuring, pressure boosting speed shall not exceed 0.1MPa/min.交底主持人：交底人：接受交底人：安全交底记录表 编号:HYPEC-PCT-AQJD-01G-01-02-06-001作业项目名称1#炉水压试验交底时间施工单位湖北二建施工负责人交底地点交底内容1. 参加水压试验的所有人员，必须参加水压试验技术安全交底，并办理交底手续。All personnel participating in hydrostatic test must take part in technical and safety disclosure of the test, and formality of disclosure shall be handled.2. 水压试验所用压力表的量程合格，经检验合格且在有效期内，水压试验时应同时投入两只以上表计。Range of pressure gauge used for the test must be qualified, or pass inspection and be within valid period.
